This spell repairs a single enchantment or spell in an object you touch, such as a broken seal, split personality, or faded bonuses. As long as the magic is no stronger than the level slot used to cast this spell, you mend it, leaving no trace of the former damage. You may attempt to repair a higher level enchantment, however there is a cumulative 5% chance of failure for each level above the slot used

This spell can magically repair a magic item or construct, but the spell can't restore physical damage to such an object.
