Tank
Pull War Master Voone away from the group and put your back to a wall to avoid your Melee DPS being hit by [Cleave] .
Be ready to use defensive cooldowns as necessary as Voone hits pretty hard.
Damage Dealers
Allow for the Tank to initiate and maintain threat on the boss. If you pull the boss off the Tank, you will probably not survive here.
Do not stand in front the boss as you will take significant damage from [Cleave] .
Healers
Voone hits pretty hard. Be on top of making sure that the tank is topped off at all times.
