Tank Anub'Rekhan at the far gate where he stands before pull. He will summon crypt guardians that will need to be picked up by an off tank. DPS will want to take down the ads as soon as possible to avoid the OT taking massive damage from the debuffs.

A little over a minute into the fight, Anub'Rekhan will begin casting Locus swarm. At this point, all melee DPS need to move away and DPS a crypt guardian that will spawn. Meanwhile the pally tank, YOU, need to start running to the other side of the room but hugging the outter wall where the posion is. Locust Swarm is a big AOE that will silence and do damage so DO NOT drag it into your group.

A healer will need to follow infront of you (max range) to keep you healed and avoid the silence debuff.

By the time you hit the other side of the room, locust swarm should be over. Now rinse and repeat - just be sure to keep an eye out for locust swarm.

This is an area-of-effect ability that targets a random player and hits everyone in a straight line between Anub'Rekhan and the player, causing 4813 to 6187 physical damage and launching the affected players high in the air, who then suffer 50% fall damage when they hit the ground.

Every 70-120 seconds, Anub'Rekhan slows to 60% normal run speed and casts a spell that causes AoE damage in a 30-yard radius around him that centers around him as he moves. Remaining in the radius of effect causes a DoT debuff of 875 to 1125 nature damage every 2 seconds that stacks repeatedly, and which silences those afflicted. When he casts this spell, another Crypt Guard also spawns at his initial engage point. Lasts 16 seconds.

Whenever there is a corpse in the room (either a player or a Crypt Guard) Anub'Rekhan can spawn corpse scarabs from it. This is not on a set timer. Ten will be spawned from a Crypt Guard and Five from a player. They spawn with threat on random players and will spread out and attack random targets.
