Winter Jormungar

Winter Jormungar are level 81 jormungar that spawn when a Snow Mound is approached in Halls of Winter in Ulduar.

Abilities

 * Acidic Bite-Inflicts Nature damage to an enemy, reducing its armor by 1000 for 30 sec. Stacks up to 5 times.

Strategies
Approach the Snow Mounds with caution to avoid aggroing a jormungar pack at the same time as the patrols that roam the hallway. After you have sprung the mound, tanks should pull back the pack. DPS should wait a short amount of time for tanks to grab initial aggro (such as with a paladin Consecration) then AoE them down. This is not a difficult pull to master with a bit of good timing.
