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

Success Whenever the target becomes affected by a spell with a duration, the target takes 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
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 4d12.
