Balefire

When a target is struck with balefire, its thread in the Pattern is destroyed, in an amount proportional to the power of the balefire strike. This translates to both the target's existence, and actions up to a certain point, being retroactively erased. 

 This spell can only effect Darkfriends, Shadowspawn, and members of the 13. It deals 40 radiant damage and can sever them from the weave, preventing the Dark One from re-creating them.
