The last, and arguably hardest, boss of AQ20.

The Ossirian (or "Big Bird" as we affectionately call him) fight is not about raid DPS, it's about coordination. I would never, in my wildest dreams, attempt this fight with a PuG.

http://www.wowwiki.com/Ossirian_the_Unscarred

As of a few patches ago, there will always be a first crystal available right in front of Ossirian. This is much easier than the old way, which required you to find a crystal from the get-go.

Use a rogue on an epic mount to pull Ossy and to find crystals. Have your finder ping the minimap to show the raid where the next crystal is.

The periodic knockback can really screw up a crystal hit. Pulling aggro away from the tanks is also deadly.

To help with this, have everone (including melee dps) go to the next crystal and then WAIT for Ossirian there. That way if a Warlock or Mage pulls aggro, they will still be in range of the crystal.

Some of the best loot in AQ20 is available here, including (IMO) the best set of mage pants in the game. Good luck!

keller, the sad thing is, on my server (Korgath US) there are constant PUGs of AQ20, probably a successful PUG ever night honestly. Though on a server with Death and Taxes, Dread, and Drama all having killed Kel'Thuzad and most of those pug's being run by 4-5 members of one of the said guilds, it's not that surprising. 5 people in tier 3 telling 15 others in blues what to do works well enough to pug almost anything.

Recently my guild accidentally did this on ossirian. Basically by doing this trick you spawn multiple crystals in one spot so you don't have to run around while doing the fight. All you have to do is get your hunter to send his pet to ossirian , and get the pet to attack ossi. When ossi has come down just a few steps have the hunter FD , and make sure noone has any aggro on ossi yet, (no buffs heals etc.) ossi should run back up the stairs. If you pay attention to the first free crystal you get , you'll notice another one spawns underneath it. Just do this trick as many times as possible to get as many crystals as possible and then pull ossirian.

You will need 2 tanks for this fight because he will stun your main tank. He has a knock back so warriors will have to quickly stance dance and intercept so he doesn't go running after the warrior. Feral Bears work well here because they can charge without stance dancing AND their charge is on a quicker cooldown.

You will also need 2-3 scouts hitting any crystal that spawns besides the one in the middle or the one right by it.

The Pull:
Have a rogue pull him and then pop evasion when he gets close to the first crystal. Be sure your warrior activates the crystal before Ossiran gets to it because it takes a few seconds to activate. Do not grab aggro from the rogue untill the crystal zaps him. He hits for 6k easily against plate and you don't want him to 1 shot your tank.

The Fight:
If your scouts are fast enough, this is a simple tank and spank fight at the middle crystal. If not you will need to drag him to the one closest to the middle and then back to the middle (we did the one at the 9'oclock position)

Every time he gets hit with a crystal, he gains a weakness against a school of magic. So caster be carefull not to overaggro if one of your schools come up several times in a row. He isn't tauntable and if you aggro him will come for you.

This is the final boss in the instance. He drops his head for a quest which rewards a neck piece. The strategies posted above are all great strategies, as an overview:

Ossirian is a very unique encounter in that you must use crystals found in his room to debuff him before you can damage him. If Ossirian is not debuffed, he will enter god-mode and one shot everyone. The fight should have 3 warriors all tanking Ossirian. Every so often he will but one in a whirlwind and go to the next warrior. HE CANNOT BE TAUNTED. These warriors are responsible for kiting him to each crystal. Another designated member of the raid should run ahead of the group, preferably mounted, and look for crystals. When he spots one, ping on the map and allow the warriors to recognize they know where to go next. When the warriors get to the crystal they can click it to apply the debuff. Try to follow a circular pattern. When he is debuffed he also becomes vulnerable to a certain spell type. For a while, ONLY DOTS SHOULD BE USED, since aggro is VERY sensitive. After he is at ~70% health direct damage can probably be used. You must have at least 2 warriors alive to complete the fight.

Comment by Athryl

My guild used to always use a rogue to scout for crystals, however there is a much easier strategy if you have 2 druids in the raid.

All you have to do is put two druids in a group by themselves and have them run (travel form) in opposite directions tagging crystals that are along the outside and towards the back where the worst tornados are. This forces crystals to pop up in the middle all the time, no long runs and much less chance of him going into supreme mode. This makes the fight considerably shorter because mages aren't limited as much from moving around and can really put out the damage.

Comment by 9495

Ossirian the Unscarred is a very hard fight, not because he hits hard or has a lot of HP, but because it requires a raid of people that work very well as a team with good communication to bring him down. Without a well coordinated team, Ossirian will take out the mightiest raids.

The raid needs to be constantly on the move during this fight, bringing Ossirian to a crystal and clicking it with in a certain time before he goes into "Supreme" mode (More on that later). While moving him around his area, the raid needs to also watch out for Ossirian to envelop the tank in a whirlwind, so he'll switch to the next highest person on the aggro list. He'll cast curse of tongues on the entire raid to make healing very difficult, so mages and druids should be dispelling that immediately if possible. He also does a knockback that does around 1,000+ damage if you are in close proximity to him and should the tank be knocked away from the crystal at a crucial moment, this could spell disaster for your raid. Cyclones also spawn around where Ossirian needs to be fought which can decimate a raid if it is caught unaware.

The reason the raid needs to be constantly moving around and finding crystals is because if you do not do it within a certain amount of time and weaken him, Ossirian will become "Supreme." Being supreme means that he will be hitting everyone for about 10,000 damage a swing. The benefit is however, if you keep Ossirian in a non-supreme state, he becomes weak to a specific element and casting it on him will do 100% more damage than normal.

i only agreed to go to AQ20 for his head :) nice necklaces for it. also i found a good use of those rogue manuals. our nickname for him is mini Ra :) other drops are nice too,but i only took manual of backstab and his head. he puts up a reaaaaly good fight

Comment by 114913

This is a sweet (yet hard) boss. I love all the egyptian references in this instance, sadly with this one though they got Ossirus mixed up with Raa ): Oh well, still awsome, I do this raid even after I hit 60 cus its so damn fun.

Comment by 125428

"Ossirian's beaten body was dragged back to the Ruins of Ahn'Qiraj following the battle, where he should by all rights have perished. It is whispered that Ossirian found the favor of the malevolent force that reigns over the Qiraji, for in spite of his wounds, the construct survived.

When the mighty Anubisath awoke, he found himself transformed, his strength bolstered and his wounded head bound in the visage of a hawk."

He was Anubis-like before, but was changed, so not a mess up on their part.

*source, http://www.wowwiki.com/Ossirian_the_Unscarred
*second edit, http://www.wowwiki.com/Anubisath what he used to look like.
*third, http://www.wowwiki.com/Horusath what he is now, the only known one.

Comment by dhampir1989

Its Horus (anglicised corruption, but near enough) who is the hawk-headed Kemetic god, and he is NOT a Sun god.

He is, however, the "son" of Osiris (another anglicised name) who was killed, and his erm... third leg, was used to impregnate his wife and bring forth Horus, who was partially a reincarnation of Osiris.

Ossirian dies and is reborn as a Horusath, get it?

Comment by 51372

The fight used to be slightly annoying and slightly luck based (depending on where the crystals would pop up and if a tornado would truck over your raid). Now, however, a group of 70's should easily be able to DPS him down on the steps. For the slackers, one crystal could be necessary.

Comment by 64683

I soloed him as a lvl 80 Feral Druid today. Highly recommended for those seeking a good challenge. :)

Comment by Skorpion9x

I just soloed most of AQ20, myself (feral druid), and found it to be an excellent source of gold. Got about 40g per boss, and 75 from Ossirian, and the spell books vendor for 10g each. Great for those who want to do something a little different from (or in addition to) boring daily quests!

Comment by Gann1

Make sure you clear the Anubisaths before engaging Ossirian solo. An add while you're kiting him around the crystals is almost a guaranteed death.

Comment by soupz

Currently bugged on live. The crystals will randomly not debuff him, I have no idea why.
However, they AREN'T bugged on the first pull, so if you 1 shot him you'll be fine. Just don't try to solo him while he's enraged on your first try like I did.

Comment by Molo

After 4 wipes I came to this conclusion ...

After you use the first crystal, and it doesn't disappear, don't use it again. Just move on onto the next crystal you can find and it shouldn't bug anymore.

It seems that the first crystal bugs out all the other crystals if you attempt to use it after the first time.

Comment by 187598

Just soloed as a feral druid with no bugs or problems. The trash was harder than he was, to be honest, with meteors hitting me for 9k. I pretty much spent the entire time walking backwards, looking for the next crystal. Easy money.

Comment by 5661

Confirmed on the bug. We activated crystals and they did nothing, then his Enrage wiped us.

Comment by soupz

I've confirmed what Molo (and Dumdedum earlier) say: don't re-use the crystals and you'll be fine. Nice catch!

Comment by 237132

80 unholy tank dk, easily soloable.

Comment by 289360

Soloed as a Blood DK 80, didnt bother with crystals, just tanked through enrage

Comment by 291405

Solo'd as an Unholy DK in DPS gear and Frost Presence. I didn't bother with killing the trash around him, as you can afford to wait to get to a crystal if needed (his enrage isn't bad at all).

Comment by 64664

Ok I see the last couple of comments are rated down.
Just gave them an Up as it's good to know what classes and talent specced can this one.

I would like to know a bit more though. Like how much damage he did when not touching the crystals.

Comment by 186001

Just did this as a DPS Unholy Death Knight. Fairly easy.

He hit me for 1500 or so while "enraged" with around 22k armor, once debuffed he hit for around 500. He doesn't do much. He has a short stun called Envolping Winds. I remember that lasting a long while when I did this at level 60, but it seems to only last a couple of seconds on a level 80. He casts War Stomp which is a knockback that hits for around 700. Also, he casts Curse of Tongues (not relevant for me but might make soloing this as a caster/healer harder, if it's even possible).

Comment by Arzanot

Just soloed this guy on my prot warrior (1200 BV approx and 31 % block), fairly easy, and idd his patrolling guardians (when they have meteor strike) hits alot harder then he does.

Its fairly simple. u pull him check of the first pylon and just move on from there, making sure u get his knockback with ur back facing towards a succumbed pylon. I used some dps items for crit and had 30 K hp buffed nothing much. never needed to use shield wall, used Enraged Rege once, if u time it good and the knockback takes u max range u can manage to bandage for a few secs. Helped abit.

For the ones who want a bigger challenge, and lesser mobs to clear, u can just finish off half of the guardians patrolling and just avoid em during boss, they dont add upon commencing battle anyways.

Comment by 302485

I was also just able to solo this guy on my prot warrior. Similar block value, 29% block, 26k hp without self buff.

Three things that helped me a lot: aggro him while mounted and ride to the first pylon. This allows you to activate the pylon before he can smack you while enraged. Second, activate each pylon about 8 secs before the buff is going to run out, as the pylon takes a few seconds to activate. Third, he will knock you back once during each buff cycle, so don't go backward all the way to the next pylon, let his knockback do it for you (and as the previous poster mentioned a little bandage is a great idea).

As for the guardians in the room that cast the meteor, after the first one hits you, simply kite the mob backwards and you shouldn't get hit by any more.

Comment by Returner99

I couldn't have druids, Death Knights and warriors running with all of the credit, so I pulled myself together and got my Protection Paladin to the ruins.

First time I tried to solo him, and it went alright-ish. The trash were by far the hardest, as the meteors were close to killing me several times.

Anyway, about the boss.

I used pretty much the same tactic as mentioned above, by kiting him to the crystals. However, I was slacking a bit, and only went to the crystals once the debuff was a 3 seconds... bad idea. I was hit several times by 3k damage, so it ended up with me having to use Lay on Hands at 20%.

All in all... it's pretty easy, yet it's not just a "kite around in a circle" fight like Kurinnaxx, so it was quite entertaining as well.

But anyway, just activate the crystals 8 seconds or so before the debuff runs out, like Warkos mentioned above

EDIT: Changed "adds" to "trash"

EDIT 2: My gear was the best available from heroics + some 10-man Naxxramas gear.

Comment by nemspyda

Annoying but pretty easy as a bear druid - main issue is the odd time when you get stuck in an area with no nearby crystals.

Comment by 316741

Kiting the guardians that throw meteors does not work. I got hit every single time. In addition, I also encountered the bug where the first pillar does not go away and if you hit it again it causes all the pillars/crystals to not work.

Comment by Khanor

just did this fight as myself (80 prot warrior), 80 holy priest, 80 hunter and 54 pally, all 80s in naxx/os gear. the pally died almost immediately from the thunderclap looking thing but otherwise not too bad, took us two attempts to clear not using the crystals as los issues broke the heals but the second try went fine.

easy tips:

- take him on the steps, facing one side or another. you wont get thrown too far.
- a hunter pet is a great offtank when your MT gets stunned.
- he can be fought without worrying about the crystals, hits for maybe 1.5k-2k melee damage, easy to heal through.

good luck all :)

Comment by 187899

80 fury war (me) ret pally and resto druid did it without crystals, not sure what the big deal is x.x

Comment by 325923

Soloed last night on my 80 Death Knight! Not to bad, definately have to kite him back to the crystals since no good healing is present.

Comment by 336890

2 Manned with 2 Shaman

1 Resto - 1 Elemental (both with instant cast ghost wolf)

This fight is Bugged

It is still possible to do this fight, but it takes a lot longer and you have to keep aware of what's going on.

What we did: Resto shaman mounted up and ran up to the platform where Ossirian stands. Run back to the first crystal and stand in waiting. (Because this fight is bugged) You need to make sure that Ossirian is literally ON the crystal when you activate it. (If you don't you will risk not removing his buff) As soon as we popped the first crystal we'd pop ghost wolf and run to another crystal. DPS him down until he gets to about 8-10 seconds left on his debuff, then pop the next crystal. Sometimes you will cut it so close that you won't be able to DPS him down in between crystals, so the fight can take longer that way.

He will take turns putting each of you (if you're 2 manning it) into a whirlwind. During which time you cannot move or cast spells. He also does a knock back (which can be good and can be bad) His knock back will remove the whirlwind effect if he's close enough to you when he does it, but it can be bad if you're lined up at your crystal DPSing him waiting for the timer to tick down. Rush back to the crystal and tap it and move on to the next crystal.

This fight is especially hard for casters because of the curse that he puts on you (reduces casting speed by 75%). So if you don't have a way to decurse this fight can be intense.

If a crystal instantly respawns don't think that you're just lucky! Don't click it! It will bug all of the other crystals and you will not be able to debuff the boss.

Good luck and have fun!

Comment by 86726

Duoed quite easily prot/holy pallies. He hits me, a heroic/10 man naxx geared tank for about 1.5k (after block). The holy pally, also naxx and heroic geared, was able to easily heal through it.

Really the only complication were the occasional 8 seconds she'd have to tank while I was stunned. That proved to be no real issue wither. She never got below 25% health.

So if you do duo with with a healer, be sure they know that they'll have to heal themselves occasionally.

We didn't take too long, so the enrage timer didn't set in. Didn't even know there was an enrage until I read the comments here.

I should add that we didn't bother kiting, and just killed him near the bottom of his stairs.

Comment by 175233

Soloed by 80 Blood DK, DPS spec in mostly Naxx tanking gear, with some blues thrown in. It's funny when bloodworms tank. As noted above the guardians are actually worse, and specifically those that are frost/shadow immune.

Comment by 233332

How to solo as a feral druid: Pull him while mounted, run to the first crystal (at the foot of the stairs), go bear form and activate it when he is about 15 yards away. As soon as he gets the debuff, the next crystal will appear. It will always be nearby; spin the camera around as you do your normal Maul/Lacerate/Mangle/FFF, and when you see the crystal, begin backing toward it while continuing to DPS. Beware his knockback, which can knock you past the crystal if you try to get there too fast (he will knock you back once per crystal switch). When he has about 8-9 seconds left on his debuff, hit the switch to refresh it. There is no reason to cut this close! It's much better to waste a few seconds than to endure a few seconds of him hitting you at full strength.

The only thing that can kill you on this boss, assuming your gear is half decent, is tanking him without his debuff active. He kills you pretty quickly that way, and he moves too fast to escape using Dash or Travel Form. Therefore, the only trick to the fight is making sure you always know where the next crystal is. It will spawn within sight of the current one, as soon as you activate it (you may need to turn up your viewing distance if you normally run with it lower than max, I'm not sure).

It's a fun fight and quite lucrative. It also tends to impress people that you can solo a 20 man raid. Don't tell them how easy it was. ;)

Comment by Horrible

Soloed at 80 with Ret Paladin in Deadly/pve gear and Titansteel mace/shield. judged Light, Seal of Corruption, Blessing of Might, Devotion aura. this was my first attempt so I played it defensive and relatively safe. I find that sword/board + corruption works quite effectively against Kurinnaxx as well after he hits frenzy.

very simple fight, I cleared most of the guardians in the plateau pre-pull (with fire resist aura, consecrate, seal of light and two-hander). approach Ossirian mounted and pull to the first crystal, it takes about 5 seconds for the debuff to kick in after clicking, and it lasts for 45 seconds. that 45 seconds will be used to navigate and kite him to the next crystal. standing back to the crystal may or may not block his knockback, it didn't make a significant difference either way. it's a good place to lay a consecration for extra damage. I waited until the debuff was down to 6 before activating the crystal, then took off towards the next one. repeat until dead. tornadoes were a non-factor, the damage is negligible.

Comment by haanzz

2 Manned yesterday (me 74 blood DK as tank+DPS and 80 resto shamy as heal)... achiv run.

Comment by zomagord

I solo'd it as a 78 blood dk in tanking gear...
it was close a couple of times and it was like a 20 minute fight lol
as long as you keep up with the crystals and keep using rune tap, and healing abilities (i'm 450 herb)
hes easy!

Comment by shoot2thrill

soloed as a blood DK in ulduar gear

I didn't even move him off his terrace... just straight up tanked him through his enrage and ignored the crystals... easy 60 gold

Comment by 163092

Did with my Prot Paladin for the first time (had been doing Kurinaxx, Rajaxx and Moam until the cash drop nerf).

I have a 1.8k passive block value set from heroics/naxx and he barely hit me.

Comment by Dragoniel

As of patch 3.2 it's still bugged up.

From about 4'th crystal (~50% boss health) they just stop working - the crystal emerges, but does not debuff the boss, the second one either as well as the next... until youre dead. Shifting out to heal/run means he'll just 1-shot you.
4 tries in a row, same scenario.

While debuffed by the crystal, the boss does virtually no damage to me. Without debuff he hits for 2-3k dmg.
Very fast, can not be kited.

Level 80 feral druid, tanking spec, PvP gear (hateful set + deadly offset items). 26.8k hp, 25.7k armor.

______________
Edit:
we have been trying to take him for about an hour and it's still the same - after activating 4-5 crystals they stop working. I don't recommend trying to solo it unless you have good tanking gear and can take him without debuff.
Im not certain, but I think his damage increases over time while while without debuff.

Comment by Keiser

Hmm I haven't had it bug on me yet and I've done AQ20 about 6-7 resets in a row. Every time I've used at least 5 crystals.

Also as a Ret Paladin you shouldn't need to use a sword/shield like the Ret poster above me. He said he played it defensively and you definitely don't need to. As long as you keep him disenraged (new word of the day) JoL/AoW procs should keep you topped off just fine using a 2hander.

Comment by 446467

Did this last night with a group of four level 80 guildies (me (Prot Warrior), Resto Druit, Ret Pally, Blood DK). We decided to do AQ20 on a whim and didn't read anything before hand.

I think it's safe to say with a tank, a healer and a couple plate-wearing DPS you can ignore the mechanics of this boss. The damage buff didn't matter since he didn't hit me often and for the brief period I was stunned the healer could keep up the others easily enough.

Comment by 352782

We did it with five 80s (frost DK in DPS gear, disc priest, spriest, hunter, rogue), keeping him up on his platform or the stairs and completely ignoring the crystals. The rogue pulled and died, but after the DK managed to gain aggro it was easy.

Comment by NokoFace

Solo'd this as a 80 Unholy Death Knight with mainly Naxx-10 gear, and 2/5 T8.5. The trick is- Don't bring out your ghoul except to heal! It's MUCH easier this way.

Since he will stun you and turn to your pet, you will be there for 6 seconds, helpless, while he beats on your pet and may even get his buff back. The stun breaks on damage, so with no pet(Gargoyle and Army count as a pet)you will instantly break, allowing you to kite him to the different pillars.

Took me about 10 minutes. I had the 2 Brew charms from Brewfest.

Comment by 479298

It seems likely to me that this guy is a Titan Watcher from Uldum, given what he's made of, his Egyptian(since the Uldum area is going to be Egyptian inspired) design and the proximity between Uldum and AQ.

Comment by 146010

Managed to solo this guy, after numerous fails at 2-manning it with a well geared feral druid friend, on my DK. Used my blood dps spec, but my dualwield tanking gear (yes, I know...) to be crit immune. Gear was mostly uld 25 quality stuff.

Doing it solo is much easier than with others, because the enveloping winds he casts on the tank is immediately broken if he hits you again. If you're with others he will march off to kill them instead.

With decent tanking gear you should be able to ignore the devices in the middle (allowing you to bypass the extremely irritating trash) and simply eat his hits, all 300% increased damage of it (melee swings for about 2.5k in my gear).

You should be prepared for a reasonably lengthy fight - I spent about 8-10 minutes taking this guy down. But as long as you don't get careless, it should be quite do-able.

Word of caution, as he seems to be pretty resistant to frost. I had multiple chain-resists of my icy touch during the fight, and it nearly got me killed a couple of times.

Comment by Jixson

Was able to easily 2-man this with a protadin and a feral druid. I was in descent gear(32k hp buffed) and druid was in better gear. He is taunt immune so just battle for aggro and handle him when the other person is enveloped inside the winds. we only did the first crystal, as it wasn't worth trying to get a nature or holy debuff from one to kill him. Quite easy fight, just remember to stay away from the whirlwinds floating around the stage or you WILL die. I had Seal of Wisdom up and was judging light to keep us topped off as he couldn't damage us enough to require a real heal. I had also given both of us Blessing of Sanctuary(yes King's on druid would probably been better), and I switched to Seal of Corruption to just get the fight over with. The trash in the room(the Anubis ones) was harder than him because of the meteor's but we both stayed in and it did about 3k damage to me which is not game breaking in any sense. Overall this fight was much easier than Kurinaxx as we forgot to kite Kurinaxx for the first 90% of the fight and were pretty much silenced for it.

Comment by thelittlevoices

Solo'd this fight and all the others as an 80 orc Enhancement shaman in 25/10man ToC gear.

very easy, never even had to use wolves. got lucky enough to get 2 nature vulnerability crystals in a row as well, which made it quite a fast fight.

Comment by wye43

50.3k hp self buffed druid solo in tank gear(heroics gear) is /afk fight.
Let him enrage, and fall asleep. He hits for 1650, you absorb 1500, you heal back from IAotP.
Average 1505 dps on him, no CDs activated except Berserk to speed it up.

About 4-5 minutes, but its easier than chasing the crystals.
When I was raiding this dude in vanilla I never though this would ever be possible.

Comment by humma

Resto shaman toc 25/10 gear 3300 sp
Demo/Affliction warlock toc 25/10 3200 sp

killed him without any crystal or whatever, just let doomguard tank and i (resto) had to riptide once in a while. he had some 300% dmg debuff on him, didnt figure why that ... perhaps because we only killed Moam, Kurinnaxx and General Rajaxx.

he stunned the doomguard and tried hitting me, i have 18k armor, 20k hp... and he hit me for 3,6k average.. nothing special. just the resistance made it a long fight

Comment by 169126

Relatively easy fight to solo for an 80 Enhancement Shaman in T9.

Basically you just gotta keep dragging him along to each crystal and hope you get a Nature buff to speed the kill up a bit.

Wolves arent even really needed except for when hes got his enrage up when trying to find a crystal.

MAKE SURE you dont drag him onto any of the broken pillar pieces on the floor as it WILL bug him out and cause him to spam summon you if you decide to get out of his melee range!

Comment by Wowhelper1

You can 5 man this with two geared AQ40 60s and 2 healers one shaman and one priest both decently geared and a runner to find the crystals. it is very effective not much coordination necessary.Done with only vanilla gear and enchants:P

Comment by Ingek

Just did this today on my warrior. Used prot gear with an arms PVP spec for Second Wind (He will use his stun quite often which gives you a lot of healing). Took forever but once I go the hang of dragging him to crystals and using them at the right times, HP stayed relatively stable with second wind. Use enraged regeneration whenever it's up to stay topped off.

Comment by 274557

Really easy to solo, as a DK blood never went down below 80% hp, just turn the crystals on when you see 'em and dps him down. He died at 4th crystal, with semi-dps spec for soloing, heroics/ICC 10 gear. Should be easy enough for any heroic geared people

Comment by 598188

easily soloed by rogue with right spec and lifewrd on weapons

Comment by 610886

this guy is probably based on Osiris, the Egyptian God

Comment by 258919

Easy solo as an 80 feral druid with 5.2k GS. Didn't go below 75% the whole time with ILotP. While it's probably possible for a well geared tank or a paladin tank to just as easily do this without removing the 300% damage buff, I decided to do it anyways. Just kite him to a crystal and hit it.

It was a long fight but not a very tough one.

Comment by matornot

Solo'd as an 80 PvE afflic lock. NOT fun. If I were to come back, I'd respec to PvP afflic for the Demonic Aegis, Fel Domination and Soul Link.

1. Use Demon Armor for the armor and healing boost.
2. Pre-summon a VW and pop Sacrifice.
3. Quickly summon an imp, who must be on passive with Phase Shift enabled.
4. Run up to the stairs to pull the boss, then run to the first crystal. Activate it when he is about 15 yards away (he starts walking much faster when he gets to the bottom of the stairs.) The crystal will take a few seconds to kick in, which is why you used the VW sac.
5. Cast CoE as soon as he is in range. This is very important because he has very high resistance and it can totally screw you up since self-healing is so important on this fight. Next get Corr up so it can start siphoning life. Then do UA and Haunt, proceeded by Drain Life as filler. Keep up all the debuffs with Haunt>Corr>UA as priority.
6. Once you've initally applied all your dots and your health is stable near 100% (you might have dropped down to 25% or less), start back-pedalling to the next crystal, and activate it as soon as you get to it.
7. Repeat step 6 until the boss is dead. If you get lucky and get the Shadow crystal debuff on the boss, you might want to pop a potion and start spamming SB if your health is full, otherwise take advantage of that time to heal yourself to full.

The most important thing about this fight is to not let the crystal debuff fall off the boss, or he will get the 300% damage buff and 3-shot you. It took me many tries and I might try again next week as 56/15/0.

I suggest you ignore thee whole crystal searching(died trying to find them) and just go balls to the walls and tank him there. I was in naxx10 gear with a few icc 5 man heroics and i did just fine.Just keep diseases up for death strike and use some defensive cooldowns every now and then.

last boss of AQ20

Comment by Thottbot

Maybe not ur kinda items but that staff can be pretty useful to a druid. maybe not as useful to a druid as to a mage or warlock but still useful.
not to mention that the mace could also be a warrior mace =)

Comment by Thottbot

He is very easy once you know the plan. In the area where he is located there are crystal things on the ground. Basically you have someone riding ahead to find the next crystal and you lead ossirian to it, when he arrives you click the crystal and it debuffs him so that his hits arent as powerful. Just keep leading him to the next crystal while dpsing and dotting him and he will go down after a few minutes. If he hits anyone without the debuff he hits so hard that it will kill some classes in 1 hit.

Also make sure to avoid the tornadoes that blow around his area as they can do a fairly high ammount of damage

Comment by Thottbot

Here's a vid demonstrating the strategy. Thanks to the Braq-Mortalis guild:

Personally I have done the fight, and it is kind of a pain for a caster since you can never sit still for more than a few seconds.

Comment by Thottbot

he may be somewhat difficult but he is nothing compared to chromaggus. Chromaggus is easy when you've done em alot, Oss is by the far the most fun and difficult fight above all AQ20/ZG/MC fights but not in comparison with bwl, bwls much more fun/challenging with all bosses

Comment by Thottbot

the cool thing about this fight is it has so little to do with your gear. once you get the strategy (which may take 15 wipes), its pretty simple. id say you could do this with greens/blues if you could get this far and everyone knew what they were doing

Comment by Thottbot

downing this boss had to be the most memorable experience i've ever had on wow. if you hit a tornadoes or your tank dies your pretty much guaranteed to wipe.

u get a rogue to mount around and navigate the crystals via pings and watch for tornadoes and mages decurse/dps and get all the other classes to do they're jobs. always let tanks gain threat for the first 2 crystals before u nuke. the rest is pure luck.

Comment by Thottbot

quiet easy if you have the right strat and the right mixture of classes.

Comment by Thottbot

how much cc rep does killing him give?

Comment by Thottbot

My guild just downed him tonight on our 3rd attempt. The 2nd atempt the healers couldnt get Mt because of the LoS of the pillars.

-We started the fight by a rogue on his epic pulling ossiran to the 1rst crystal. The rogue cont. to ride on his mount searching for where a crystal spawned. He would then ping it on the minimap.

-Ossirian is in a 'god'mode, where he hits like a beast
+pulling him to a crystal then opening it takes him out of 'god' mode for 45 sec, he will become vulnerable to 1 class of magic, his resistance is reduced by 100% and dmg taken increased by 100%

-There will be 2 MTs, they have to be 1rst and 2nd in threat or you will wipe. One Mt will occasionaly become engulfed in a tornado and lose aggro, then thats when the 2nd MT moves in. The MT will bring Ossirian to the next crytal, healers must be on the MTs ass and moving w/ him.

-Move Ossirian before the 45 secs is up and you should be fine.

The best part of AQ 20 is the mobs in his room, most fun eva. Just pay attention and all should be good

Comment by Thottbot

for some reason, ignite seems to go crazy on this guy when he is vulnerable to fire.

CoE was on him, i scorched 5 times to debuff him to fire, and then i poped combustion and the talisman of ephemeral power and pst'd a priest for power infusion...

i fireball crit'd for 6200 and ignite hit for 3700 (which wasnt mathematically correct, since ignite is supposed to be 40% total, and only 20% per tick), then i crit'd with my next fireball for 5700, resetting the ignite timer, and ignite hit for 7200, and i was like WTF? 7200? then ignite hit for the second time for 7200 and ossirian is running at me and i wipe the raid...

i thought maybe that another mage had also crit'd to make ignite stack... but then i remembered i was the only mage in the group. so, has anyone else noticed ignite hitting for a much higher percentage than normal on him? 31,000 damage in 2 fireballs because of a screwed up ignite. i calculated that instead of 40% over 4 seconds, it was doing 120% for some reason.

Comment by Thottbot

Dropped him today, he droped killer items, it was fun :P

Comment by Thottbot

Ye, really funny, killed him around a month ago. Actually pretty hard, we had about 10 level 70's with avarage epic gear :S. Must been really hard at 60, never had the chance to meet him pre-tbc :(.

Got the head too ^^

Comment by Thottbot

A PUG raid of 15 or so people on Gnomeregan just cleared the entire raid instance in 2 hours. It was great fun and a break away from all the new lvl 70 crap. It was just about having fun, not getting good loot. We are planning on doing molten core soon, and then other old world raids.

Comment by Thottbot

Probably possible to 5man with 2tanks, 2dps & a Healer @ 70.
Just keep him in supreme mode constantly, would love to try.

Comment by Thottbot

15 random people nuking him is enough now.

Comment by Thottbot

I'm an 80 death knight and I duo'd this with an 80 priest healing pretty easily.
In fact we duo'd the entire instance no prob.

Comment by Thottbot

80 dk unholy solo'd him in dps gear while in frost pres.. had to clear room though tried to kill through enrage but he crits for 6k.

Comment by Thottbot

Just wacked him me Unholy DK in my tanking gear, and a holy priest. Both 80.

My little ghoul offtanked when I was stunned, and things went well. Consider throwing a army of the dead at around 20% tho. As the healer will surpass the ghouls aggro by then.

He hits for 3-5k on 24000 armor.

Comment by Thottbot

Just soloed him as feral druid.
Keep up the debuff from crystals and other than that just tank and tank.
If anyone cares, the stun gets removed when hit.

Comment by Thottbot

Soloed as a Ret pally in mostly Naxx 10 gear. Kept up Seal of Light, Judged Light and made sure to use instant flash of lights when they were up. Was fairly simple. Clearing trash took longer.

Comment by Thottbot

solo'd him tonight on my 80 feral druid... am T7-7.5 geared.... stealthed through the instance up to him, only fighting where it was needed... the actual fight was pretty easy, although it did take a bit of time to do solo.... couple of times he got me down to around 30% health so i popped Frenzied Regen with the glyph and got back up to 100% in no time..... just keep kiting him to the next crystal and you're sorted :)

good luck.

Comment by Allakhazam

Killed him Friday night - Point to make on this encounter:

the Crystal gives a massive debuff to a specific spell family - 100% debuff which will continue if the next crystal debuff's him before the 30 seconds expires.

DoT's and even drain life will go up exponentially in terms of dmg. this creates huge amounts of aggro and you dont want to aggro him off the MT - slows you down from getting to the next crystal and causes more confusion. Recommend DoT's and lots of lite range dmg. Wands if possible until the 3-4th crystal and then intermittant bursts of casts and ranged dps.

Also if you get one shotted in the early portion of the fight while going to the first or second crystal, there should be more than enough time to return to the battle even if walking while in combat on the zone in. overall a really fun fight. be ready to run around is an understatement, the room (area) the fight takes place in is 2-3 times larger than the area Onyxia sits in and the pillars affect LoS with the crystal debuff.

Comment by Allakhazam

well heres how it went......ok so we got 30 ppl from my guild. they were all 70's. but wehn we got to obsirrian we realized we didnt have a group for crystal clicking. so 4 ppl had to click them and they are all rogues. one guy aggroed even more guys and forgot to click the crystal and then we all wiped lol. so sad

Comment by Allakhazam

rogues do alot of dps in this fight.

Comment by Allakhazam

umm yes he can one shot a tank in full T2 soo yes he has hit our MT for about 9k

Comment by Allakhazam

drops? (first!)

Comment by Allakhazam

Mostly all caster loot

Comment by Allakhazam

This guy, just as Hakkar, is primarily a caster-looter.

Will he do less damage the more crystals you press, or just for a short period of time?

Comment by Allakhazam

Why should rogues do the pinging? We have a hunter do ours. And mages wont often be at the top, we've got a DPS warrior topping ours.

Comment by Allakhazam

Two tanks. One rogue scout (rogue *must* stay mounted).

Assign at least two healers per tank.
-(druid+priest & sham/pal tertiary backup healer).

Place Amplify Damage (mage spell) on everyone.
-The +150 Healing goes a *long* way.
-There is no magical damage in this fight except the tornados.
-If you get hit by the tornado you're dead regardless.

Casters shouldn't waste mana unless it is a debuff that affects their specific type of spell.

Arcane, Nature, Fire, Frost, Shadow.

That should do it. :)

4k-5k damage on cloth? you gotta be jokin,
he does even 13k on leather

Comment by Allakhazam

mostly right for the "Fight Description", but you need to get your facts straight. enveloping winds is what OSSIRIAN casts, NOT the sandstorm. He will cast it on the player hes agroed on randomly, so 2, if not 3 tanks are what you need for this fight. also, none of you messaged the tornados that will travel around the room. If you get caught in this tornado, your pretty much dead. its very easy to see, and very easy to avoid. rogues will NOT do "the most dmg" in this fight because Ossirian casts a thunderclap attack. it will kill them quickly, and healers cant spare the time to constantly heal them, because they need to focus on the tanks. My guild has AQ20 on farm heh, and we have twin emps down in AQ40. (www.guild-am.com). Hes a very fun fight, and once u get it down, hes very easy.

Comment by Allakhazam

last night we got the message that he was "Now Resistant to Curse of ***"

Anyone know what this means? it happened quite a lot.

Comment by Allakhazam

gg rogue wearables.

Comment by Allakhazam

One rogue drop? I don't see one. I suppose at the outside you could consider the crossbow a rogue item... but I don't think it's better than Striker's Mark (or even Ancient Bone Bow).

Yes, the neck reward for handing in the head is nice, but other classes get the same love. And no sword, either... or even a sword equivalent of the Muggers Belt would be nice. Too much to hope for, I guess ^^

Comment by Allakhazam

I don't know why all of the strategy guides say that Rogues cannot dps this guy. I know he uses an aoe thunder clap ability but it really doesn't happen to often and is very easy to bandage away every time it happens. I got really lucky when my guild did it this past weekend because Ossirian got 3 or 4 Nature vulnerabilities in a row and my Deadly Poison V was ticking in the 600's. All in all, it's a very fun fight that shows some creativity lacking in some of the earlier additions to the game.

Comment by Allakhazam

Involves kiting the boss all around a large room near crystals that randomly rise above the ground (random by time, not by position which is consistent from attempt to attempt). Activating these cystals debuff Ossirian so that he doesnt do his normal 4k-5k damage (on cloth).

He also picks up random vulnerabilities (ala wyrmguards in BWL) and they can potentially "stack" (frost one and shadow one can be up at same time, for example). The vulnerabilities allow for 100% Damage and -100 Spell Resisitance for a particular type of spell (i.e. 100% Frost Damage and -100 Frost Resistance).

One caveat is that a sandstorm travels around the room which debuffs players with 'Enveloping Winds' if they are caught in it.

Comment by Allakhazam

When this guy goes into supreme mode he's like Boom Headshot, Boom Headshot, BOOM HEADSHOT!

Comment by Allakhazam

How are we gonna see where the next crystal spawns? Should we get 1 person checking the whole place or something else?

Comment by Allakhazam

There's a much easier way to beat this guy.

Get two people to run around the edges of his courtyard and click on the crystals as fast as they can. This forces the crystals to immediately respawn in the middle of the chamber.

Everyone else fights in the middle, which is now full of crystals.

More crystals = less running = more healing + more DPS = much easier fight. This guy is pretty much a joke with this strategy.

Comment by Allakhazam

Nice Rogue loots!

Comment by Allakhazam

i just killed him with my lvl 20 Dwarf Paladin... i Just danced and he went crazy and commited suicide, just like the rest in AQ.

Comment by Allakhazam

Got him down to 22% with only eleven people. Probably can be 10 manned.

Comment by Allakhazam

The hammer is a rogue drop.

Comment by Allakhazam

took him with a pug tonight, got him in the fourth try

all caster loot dropped and i got nothing =), but well fun fight and he critted me 20997 wich is almost the same as ony deepbreath

Comment by Allakhazam

Comment by Allakhazam

Does anyone knows that you have to kill Moam, Buru or Ayamiss before you can pull Ossirian? 'cus there's a way to move around 'em.

Another boss with TERRIBLE mechanics in one of the worst raids Blizz has ever designed. Spent the whole fight being cycloned, not able to fight or do anything. So unbelievably stupid.
