A powerful force disrupts magical effects on the target, removing ongoing spells that have been cast on a target. You must make a caster level check of 1 to 20 + your caster level (no maximum) versus 11 + the spell's caster level to remove a spell effect, and magical healing being applied to the target is greatly reduced for 30 seconds. Your target must almost make a Will save for they will be unable to cast for the duration (excludes bosses). If the target is a construct or living construct they are destroyed on a failed save.

If cast on a Spell Ward trap, this spell will reduce the level of the trap by 1 to 8. If the level of the trap is reduced to 0, the trap is disabled.
