Ayamiss

Spells:

Stinger spray (??yd radius) - AoE of about 1000dmg to all enemies
Poison stinger (melee) - applies a stackable poison that causes 25dmg per second per stack (up to 100stacks) to target with aggro
Paralyze (??yd) - snares an enemy at the altar for the grub to feed, grubs are very quick
Summon Hize'Zara swarmer - summons a dozen that can be a problem for cloth-wearers, easily killable
Taunt-immunity - **applicable in Dalaran?**

Battle Strategies:

Tank'n'Spank (minimum 1 tank, 1-2 healers, 3 DPS 2 of which rDPS ) Phase 1 (Airborne, >70%HP)

Positioning should reflect that of grub spawn points (altar and corners)
Melee have the primary role of killing the grubs, yet can do ranged attacks during downtime or bandage as needed to help healers
rDPS have primary role of DPSing Ayamiss to begin phase 2
If raid has tanky rDPS with good nature resistance let him/her keep aggro on Ayamiss
Healers will determine the max amount of poison stinger stacks that rDPS should accumulate before giving aggro to someone else
rDPS that have threat-reducing abilities should be the main aggro'ers (hunter, priest...); the rest should stay below aggro or stop DPS well before the max amount of stacks specified
Nature resistance eases the fight

Phase 2 (On Land, <70%HP)

Let tank acquire enough aggro at the beginning before DPSing since Ayamiss may be taunt-immune
Tank will be near stairs to altar with back against wall
Continue killing grubs immediately when they spawn
