Moam

The 3rd boss of 20 man Ahn'Quiraj

Abilities:

Arcane Explosion - Moam will give out the message "Moam bristles with energy" and fire off a arcane explosion dealing 1k-3k damage generally a wipe.

Trample - Ability hits in a arc infront of Moam dealing around 1-2k damage.

Stone Form - Moam will turn to stone at some points increasing his armor and regen, he will not attack and has no aggro.

Mana Drain - This drains 5 players of mana draining 500 and giving Moam 1000.

Boss Fight:

MT attacks Moam and starts getting aggro, the key to this fight is to keep Moam mana drained at all times. Once your MT has a firm aggro level from Moam have DPS move in and start killing.

Priests will be required to mana drain Moam making it your druids, shamans, and paladins jobs to heal the MT. Save mana for the healer's and have everyone else bandage.

Around 90 seconds into the fight Moam will summon 3 mana fiends, these fiends deal a very deadly AoE that can deal 1000 or so damage. As soon as they appear warlocks must chain banish them.

Moam will use stone form now which lasts either 90 seconds or until he gets 100% Mana. Everyone must DPS like mad while warlocks/priests mana drain him. You have no need to worry about aggro while he is in stone form.

Once Moam comes out of stone form you will most likely be low on mana/general raid HP. This is the critical point of the fight, DPS like mad to get him down before you run out of mana/Mana fiends get free.

Once Moam is down let the fiends un-banish one at a time and kill them, they are extremely easy when you are only taking them down one at a time.
