Terestian Illhoof (patch 2.4.3)

Optional boss in Karazhan.

Use fire resistance totem and magma totem here. If you start to see a lot of imps (8-10+), you might want to throw down a fire elemental totem to help out with the AoE.

Every now and then, a random player except the tank will get sacrificed in the middle of the room. The person being sacrificed needs lots of heals because he or she takes about 1.5k damage per second until the Demonic Chain is destroyed by the raid group.

Keep earth shield up on tank.

Save bloodlust until the room gets overwhelmed by imps or when Illhoof is near his death.
