Overview Gormok will linger by the door for less than 10 seconds after his entrance, after which he will attack your raid - have your tanks ready to pick him up. Compared to other fights, Gormok is very close to tank n' spank. He will apply a stackable DoT on his current tank, which will force a two-tank-rotation every 2-3 stacks. He also has a point-blank AoE - your melee DPS will be taking some damage as well, and the tanks - even more. Casters should stay spread out at ~20 yards away from the boss. To bother the casters, Gormok will throw Snobolds at random raid members (he seems to prefer ranged, but it's entirely possible for melee to get them too). The Snobolds will stay at their target's back and interrupt any non-instant spellcasting from both their target and other casters nearby. Those should be killed quickly. The last thing to watch out for are fires on the ground. These are spawned by the Snobolds, so you can stop worrying about them when you stop worrying about Snobolds (as there is a limited number of Snobolds spawned).
