• The sides of the boss room contain nests of eggs. These eggs work the same as the eggs in UBRS. Don't go near them or else whelps will spawn.

Phase 1:

• Onyxia Tail Sweeps anyone standing behind her. Don't stand behind the boss, stand to the side.

• Onyxia occasionally uses Wing Buffet, which does damage in a cone in front of the boss and knocks players back. Don't stand in front of the boss unless you're the tank.

• Onyxia occasionally casts Flame Breath on the tank, dealing 3063-3937 fire damage in a cone in front of the boss.

Phase 2 - 65%:

• Onyxia flies into the air for the duration of this phase. 

• Onyxia will randomly shoot a fireball at a raid member. This fireball deals damage to the target and everyone within 8 yards, so it's recommended you spread out during this phase.

• Onyxia will occasionally cast Breath. When casting this, everyone will get a message that Onyxia is "taking a deep breath". Onyxia will deal fire damage in a massive line across the boss arena. The line that she breaths through is based on where in the room she is located. Below in Red is the possible lines she can use Breath. The Blue are the parts of the arena that are safe during that Breath.
