Overview Soon after Gormok has been defeated, Acidmaw and Dreadscale will come to the arena. Dreadscale will be mobile and follow normal tanking mechanics, while Acidmaw (who spawns a few seconds after Dreadscale) will be stationary. Every so often the two jormungars will burrow underground, and as they emerge, they will switch - the one that was mobile before the burrowing (Dreadscale in the beginning) will be stationary, and the one that was stationary (Acidmaw in the beginning) will be mobile. Acidmaw's attacks do Nature damage. Its Paralytic Toxin will quickly immobilize and stun the tank and whoever else is nearby, making them useless for almost a minute. The only way to remove the poison, other than Divine Shield and Ice Block, is to have a player with Dreadscale's Burning Bile run to the poisoned people and allow the Bile debuff to damage them. One tick of Burning Bile is sufficient. Nobody but the tank should be standing in front of the poisonous jormungar. Dreadscale's attacks do Fire damage. Don't be in front of it either, unless you are a tank. If you get debuffed with Burning Bile, be ready to cleanse anybody with Paralytic Toxin, but to try to keep away from other people, since the Bile does AoE damage. In addition, the mobile jormungar will frequently spawn poisonous clouds underneath itself - the tank will need to kite it quickly. The stationary jormungar will do AoE knockback, not so frequently, so if you are using standard melee tank, they will need to get back in range quickly. Whenever one of the jormungars dies, the other one receives 50% extra damage for the duration of the fight.
