Flesh Horror

Flesh Horrors can be found in the Butcher's Sanctum in Scholomance. They have several s attached to them and the following abilities:

This self-buff nullifies any attempts at doing damage to the horror directly, so target and kill the Meat Grafts attached to it. The flesh horror hits hard, but runs slow, so kite it around the room. Kill all 5 grafts and the horror will die automatically.
