Overview It is important to note that the tank will get hit multiple times by the Void Blast if he is backed by a wall and is forced to stay within the effective range of the ability. The ability isn't avoidable through line of sight. To deal with the knockback it is advisable to have everyone place their back against a wall so they don't get knocked too far away. This is especially important for the healer, as the knockback could push him too far out of range to heal the tank. The large stone in the middle of the room can be used as a barrier for the knockback. Mages can avoid the Void Blast with Ice Block, warriors can reflect it with Spell Reflection and shamans can absorb it with Grounding Totem. Combat pets will be hit by the ability as well and may help soak extra damage. Abilities Melee: Has no physical attacks.
