Spirit Bolts: Malacrass will periodically shoot Spirit Bolts at the entire raid. Each Spirit Bolt does 450 points of shadow damage. When he uses this ability, he will shoot twenty Spirit Bolts at each raid member power leveling over a period of ten seconds. Line of sight will not hinder the Spirit Bolts. Dampen or Amplifiy Magic will not have any effect on the spell. The Spirit Bolts can be resisted.

Soul Drain: Malacrass will randomly target one player and perform Soul Drain. When this occurs, Malacrass will acquire several abilities from the player and begin using them. He will use these abilities against the raid until the next Soul Drain when he acquires new abilities from the next player.

Drain Power: At one minute intervals Malacross will drain 1% power from raid members and give it to himself, thereby increasing his size and damage. He will not begin to use this ability until his health reaches 80%.

Apart from these mobs, Malacrass has four random mobs with him.

Similar to Moroes in Karazhan, you will need to kill at least 1 add before you should focus all DPS on Malacrass. It is advisable to kill the healers first for two reasons: they heal and because they die quicker. If you are going to leave adds up, it's best to leave the ones alive that are the most time-consuming to kill.
