Onyxia is asleep when you first enter but when you get close, she will wake up and attack. The battle is in three phases. The first phase is a simple tank and spank fight, the tank needs to keep Onyxia at the back of the room. At about a third down, she will walk to the front of the room and take off. Small dragonkins will come into the office which the tank needs to pick and the dps need to kill down. Ranged need to target the boss. If timing has gone well, the adds will have been killed before Onyxia comes back down. The tank needs to take the boss to the bank of the room and keep her there. The dps need to take down the adds and the boss, when the boss dies, the adds disappear.
