Mephistroth is the leader of the nathrezim, and is the final boss of the third wing of the titan's siege halls.

Strategy
Mephistroth switches between his three phases every 35 seconds. In the 5 seconds in between, he is weakened, taking twice as much damage from all sources. However, after a fire phase or strength phase, you have less time to attack him during his weakened state because of the raid-wide stun that comes with blast wave and war stomp.

In his Shadow phase, he casts shadow bolt on the tank every once in a while, but the main change is the buff to Creeping Shadows. With a higher movement speed as well as damage and size, this makes it easier and more fatal to be caught by a creeping shadow. If someone stands in a creeping shadow for more than 3 seconds, he will become mind controlled, doing 10 times more damage. It is hard to do anything about him, though, as attacks against him have a chance of spreading the mind control to the attacker, quickly overwhelming the group. When the Shadow Charge is removed, he casts Shadowbolt volley on the raid, the only one of the three phase-enders that doesnt do a stun.

In his Fire Phase he casts fire ball on the tank every once in a while, but the main change is the buff to the flame serpents. With twice the hp, damage, and speed, it is now easier and more fatal to be caught by a flame serpent. The whole raid must concentrate on the flame serpents when they spawn during this phase. The damage from the flame serpent's strangle is almost always fatal even without a flame charge, and with a flame charge, well, just don't get caught. the phase-ender here is a two second stun + fire damage; Blast Wave.

In his Strength Phase he deals extremely heavy tank damage, to the point that healers will have to spam heal to keep the tank up, through both twice as much damage from cleave and melee swing, as well as the raging strike, dealing four times the damage of a melee swing in a fire or shadow phase. His phase-ender is a war stomp, stunning the raid for the whole 5 seconds of his weakness state.
