Blackwing Warlocks are level 61 elite humanoids found in Blackwing Lair.
Casts a Rain of Fire that does 925 to 1075 damage per tick, also summons Enraged Felguards. These mobs must die first as they have the greatest potential to wipe the raid. Summoned creatures must be kept banished while everyone else needs to run out of the rain of fire quickly. They are immune to polymorph and have roughly 100k health. The summonables should remain banished until the rest of the lab pack has been killed, at which point a tank can pick it up. Felguards can also be Feared if there aren't enough Banishes to go around, or if the raid is just that ballsy.
