Encounter 1 / 1 · Onyxia's Lair (level 80)
Onyxia
Onyxia’s Lair · Ground-phase threat, airborne adds and final-phase fear at level 80.
Raid priorities
- Tank Onyxia facing the north wall and keep the raid at her sides.
- Control whelps and Lair Guards during the air phase, and avoid Deep Breath’s path.
- Ease off damage before landing and let the tank re-establish threat and positioning.
- Coordinate fear protection during phase 3.
Before the pull
- Review the tanking, healing and damage responsibilities for Onyxia in a 10- or 25-player group.
- Mark safe flank positions, Deep Breath escape routes, add-tanking positions and the landing location.
- Assign interrupts, dispels, crowd control and target swaps before the pull.
- Save raid and personal cooldowns for the encounter’s most dangerous phase.

Role notes
Tanks
- Face the boss and adds away from the raid; swap tanks when required by debuffs or phase changes.
- Tell healers in advance when you will use defensive cooldowns or make a dangerous tank swap.
Healers
- Assign tank healing, raid healing and dispels before the pull.
- Plan raid cooldowns for the largest predictable damage window and avoid unnecessary overlap.
Melee DPS
- Stay clear of frontal and rear attacks, and switch to adds as soon as they are called.
- Don't sacrifice movement or soak mechanics for damage uptime.
Ranged DPS
- Maintain the required spacing and prioritize distant adds, orbs or moving targets.
- Save abilities used while moving for mandatory transitions.
Raid utility
- Agree on interrupt, purge, stun, slow and immunity rotations depending on the encounter.
- Use a combat resurrection only when the fallen player’s role is essential for the next mechanic.
Nerfs: what changed
- The boss-specific history is read together with the Onyxia's Lair (level 80) raid timeline; original Wrath and Wrath Classic are kept separate.
- This is the level 80 version, not the Classic 40-player encounter.
- Level squishes, Timewalking and changes to soloing from later expansions are outside the scope of these level 80 tactics.
