Ossirian is the final boss of the Ruins of Ahn'Quiraj
This battle takes place in a room full of crystals and is like Buru the Gorger, a very different fight compared to the normal tank and gank style of play.
Boss Abilities
Curse of Tongues - Ossirian has a AoE debuff Curse of Tongues increasing casting time by 50%
Enveloping Winds - This hits whoever is Ossirians current target/Highest aggro causing a 8 second stun and loss of aggro similar to being kicked by a Molten Giant
Warstomp - Melee range AoE deals 1k damage knock back and additional fall damage of 400-600
Supreme Mode - Ossirian starts the fight in supreme mode and is deadly when in this mode. He enters Supreme Mode frequently and can hit for more then 10k damage.
Boss Fight
The terrain in Ossirian's room is rather strange with many crystals that are destroyed to take him out of supreme mode and several mini-tornado's that spawn when you enter combat with him that must be avoided.
The Fight follows this method, have a player ride around to find each crystal, have the tank bring Ossirian to the crystal, Activate the Crystal, repeat.
You need to assign people to MT, OT, Crystal Finder(Mounted), and Crystal Activator.
The only job of the crystal finder is using his/her epic mount to find crystals and show it to the raid. This is rather the same as the Buru fight in finding eggs.
The Main-Tank/Off-tank must be prepared to move Ossirian to each crystal as they are found, if they dont do it right you could wipe the raid.
The activator must run nearby the MT/Ossirian and activate the crystals as he approachs, activating it takes 3 seconds or so and thus should be ready to use the crystal a bit before the debuff on Ossirian expires.
The main DPS on Ossirian is Ranged, however melee is alright as well. Ossirian makes it harder to melee him with warstomp and thus they become a drain on mana for the healer's.
Once you have the strategy down you can easily move him through the room, also some guilds chose to use melee DPS and sacrifice the additional mana opting for a faster kill. |
