Ossirian the Unscarred

[Bastet]

Ossirian the Unscarred is the last boss of AQ20

Strategy:
The Pull
Rogues are pretty much useless in this fight therefore use a rogue to pull the boss to the middle of the room. The Rogue should be mounted, bodypull the boss, then head back to the middle and look for a crystal that will spawn. Two crystals will be spawned at all times throughout the room. After about 2 seconds, the boss will at this point buff himself; with the buff he can hit you for 13K damage, also when buffed, Ossirian moves pretty fast, faster than walking speed. When Ossirian is about 20 yards to the crystal, have a designated person click on the crystal to activate it. Note, the Main Tank should not aggro Ossirian til after the crystal puts the debuff on him, otherwise the MT will be one-shotted to death.


Activating the Crystals
Activating the crystal will put a 30 second debuff on Ossirian that make him hit for only 1K or so, less than than the 13K normally, and puts a vulnerability on him for specific spell damages. Put up detect magic on him and have someone call out his vulnerability. You will then have 30 seconds to pull Ossirian to the next crystal before his debuff runs out and one-shots the Main Tank.

Kiting Ossirian
The mounted Rogue would be responsible for calling out the next crystal to kite Ossirian to. A Druid or Shaman, or even a Paladin can be used to run ahead of the MT to the next crystal as the designated crystal activator, Druid/Shamans are preferred, since they can go in travel form towards the next crystal ahead of the main raid. The crystal activator can also be used to heal the MT just in case the MT runs away from the main group towards the next crystal and decurse since Ossirian has an AoE Curse of Tongues. You can kite Ossirian in a clockwise manner, and the crystals should spawn in a clockwise manner. It can also be done counter-clockwise. Some crystals spawns pretty close to each other, so the tank should just get to the next crystal, stay there for 10-15 seconds and let the rest of the raid catch up and do damage to Ossirian.

Ossirian Damages
When not debuffed, Ossirian hits for 13K, which is instant death. Highest priority is to continuously lure him to the crystals so he doesn't get to this state. If he does, it's likely a wipe. Otherwise Ossirian doesn't hit that hard. However, he does have an AoE kickback that hits you for about 900HP and takes another 700 fall damage if you're within about 10 yards. Therefore it's wise to stay away from Ossirian and only have the MT/OT close to him.

The reason why an Offtank might be needed is because Ossirian casts a debuff on the person higest on his aggro list. If you get caught in a tornado, you are stunned and take some heavy damage over time. The effect can no longer be dispelled, so when the MT gets caught in the tornado, Ossirian will aggro someone else, which is why an OT is a good idea so he goes to the OT instead of someone squishy. After effect wears off the MT, aggro goes back to him. High Nature Resistance can prevent the debuff.

Killing Ossirian
Ranged damage works best, since getting caught in the AoE knockback will cause healers to waste precious mana healing the raid. If you're not a tank and you took damage, bandaging would help healers. DoTs also work very well, keeping DoTs on Ossirian - especially the one he is vulnerable to - will take him down. Ossirian doesn't have a whole lot of HP, but since he is constantly kided to different locations, you don't really have time to just sit there and DPS him down. The fight takes fairly long, about 6-8 minutes, maybe more, and if you die early, you can run right back to the fight. Just DotT and ranged attacks should be all you need to deplete his HP. No melee damage other than the MT/OTs.
