Abilities/Spirit Burst

Spirit Burst fills your Ultimate slot. Nova ultimate ability of the spirit school. Base damage 120. Cast 14 ticks. Nova radius 6.

You get it by equipping 16 bases across 6 lines: Cinder Charm, Cinderwake Relic, Emberbrand Relic, Foxfire Relic and Heartspike Relic and 1 more.

The draft can bend it 5 ways — Echo, Area, Force, Duration and Critical — and cards that ask for area, critical and push will find it.

Between rooms it can be offered 177 cards: 48 written for it specifically, plus the 129 that any ability can take. Those cards can put Brand, Burn and Bleed on it, and attune it to Holy, Fire and Blood.

3 Uniques are built on gear that hands it to you: Last Keeper's Lantern, Summer's Last Ember and Heart of the Furnace.
