Kirrawk

Arrakoa shamanlike caster in Brawl'gar Arena. Rank 2 opponent.
Can be interrupted and stunned. All forms of CC probably works on him (needs confirmation).

Uses:
Lightning bolt : deals ~14-15k damage.

Buffs himself with 5 stacks of [spell=135234] which deals ~13-14k additional damage to his attacks. This buff is classified as magic so it probably can be purged/spellstollen etc.

Summons : [npc=54467], a cyclone which follows you for about 4-5 seconds and then despawns.
If you get hit by it, you will be knocked up in the air and slowly fall down, taking no falling damage.
This is the most dangerous attack, not only because you are not able to do anything except instant casts for about 4-5 seconds, but he also casting [spell=132673] during this, dealing ~58k dmg every 0.5 to 1 sec and more or less killing you, if you don't use def. cds or some healing.

It seems that he can also be hit by twister. So the best tactic would be standing in melee and waiting for twister to spawn and then to position yourself so, that it will go through Kirrawk and knock him up.

edit: changed rank 4 to 2 as on the liverealms.

As hunter you can delfect the damage from [spell=132673] by using [spell=19263]. It really helped me when the cyclone snuck up behind me and I got caught in it.
