Diminish Spell Runtime

Supernatural

Level11

As a standard action, you can attempt to hack an active spell effect that you’re aware of to reduce its duration. You must be able to touch the area, creature, or object affected by the spell that you want to hack. As part of the hack, attempt a Mysticism check with a DC equal to 15 + 1-1/2 × the caster level of the spell. If you succeed, you reduce the spell’s duration by 50%. If this reduces its duration to less time than the effect has already been active, the spell ends as if dispelled. If you fail the check by 5 or more, you can’t attempt to hack that spell again for 24 hours. This ability does not affect spells with an instantaneous or permanent duration.
