Destroy Arcana

An object, person, or item with magical properties is instantly destroyed. The target no longer exists and any matter and arcana making up the object is turned to ash. When cast, the target is surrounded by ribbons of light for a few moments before they are dispelled, leaving a small pile of ash. To cast on a magic user, the caster must succeed in an intelligence competition with the target. If successful, the target is killed and turned to ash. If not, the target is unaffected, knows the caster tried to destroy them, and the caster expends a spell slot. To cast on an item, the caster must succeed on an intelligence roll with a DC of 21 or higher. If unsuccessful, the caster expends a spell slot. Even with successful rolls, there is a 75% chance that the spell backfires due to its power. If this happens, a spell slot is expended with no effect.
