POE2 boss checklist

Prepare a repeatable boss attempt routine instead of changing builds after every death.

Before the attempt

Confirm resistances and basic defensive layers for the encounter tier.
Check mobility skill comfort and animation lock risk.
Bring a damage plan for short windows, not only tooltip DPS.
Record what killed you: ground effect, slam, add wave, or resource loss.
