Abilities/Spirit Seed

Spirit Seed fills your Main slot. Summon main ability of the spirit school. Base damage 10. Cast 8 ticks. Up to 4 summons living 600 ticks.

You get it by equipping 15 bases across 6 lines: Bonechoir Staff, Firstseed Staff, Mosswarden Staff, Murmurgrove Staff and Nightshade Staff and 1 more.

The draft can bend it 7 ways — Echo, Reach, Multiplicity, Area, Force, Duration and Critical — and cards that ask for summon, critical and on_hit will find it.

Between rooms it can be offered 199 cards: 70 written for it specifically, plus the 129 that any ability can take. Those cards can put Venom and Distortion on it, and attune it to Poison and Void.

5 Uniques are built on gear that hands it to you: The Overlord's Cradle, Widow's Portion, The Hundred-Handed Court, The Belfry and The Spider King's Brood.
