Spellwrack

You cause any spells cast on the target to spill out their energy in harmful surges. The target must attempt a Will save.

Critical Success The target is unaffected.

Success Whenever the target becomes affected by a spell with a duration, the target takes @Damage[2d12[persistent,force]] damage. Each time it takes persistent force damage from spellwrack, it reduces the remaining duration of spells affecting it by 1 round. Only a successful @Check[arcana] check against your spell DC can help the target recover from the persistent damage; the curse and the persistent damage end after 1 minute.

Failure As success, but the curse and persistent damage do not end on their own.

Critical Failure As failure, but the persistent force damage is @Damage[4d12[persistent,force]].
