Lithluran, The Gate Master
From THFwiki
Show Spoiler hide_message
Lithluran spawns 4 adds upon aggro, one in each corner of the four rooms surrounding him. If you aggro more than one mob, you get your buffs fully dispelled.
(NW) Anathor, The Gate Caller: Spell damage only, doesn't summon
(SW) Prankis, The Gate Caller: Spell damage only, doesn't summon
(NE) Zethuri, The Gate Caller: Tank this (can melee damage)
(SE) Kithorin, The Gate Caller: Tank this (can melee damage)
Put a tank on the NE, SE, and Boss, and kill all 5 mobs while keeping them all within 10% of each other. Use casters to damage the NW and SW corner mobs (make sure a pet is not attacking them), and adjust how much damage is needed on the other mobs based on that.
If mobs go outside of 10%, an AoE will wipe out the raid.
