Overall easy to kill boss, similar to the big bug at the beginning on the ruins of Ahn'Quiraj. This is a breeze for anyone who can get this far.

Fankriss Abilities:

Mortal Wound: Stackable debuff, reduces healing by 10%.

Fight:

Like i said earlier, this is a easy fight. You need 2 MT's for the boss switching them each time they get the debuff stacked to much, say around 5 times or so. Little hatchlings spawn everyonce in a while, fear/kill them.

Randomly during this fight people will be teleported into alcoves where around 4-5 mobs will attack them. Keep them healed and when they can exit have them run to the raid then AoE/Fear the mobs.

When your going to AoE the adds have the tank use his AoE taunt so he takes the brunt of the damage instead of the casters. This fight is an easy one, tank and gank.
