Disjunction

The spellcaster issues forth a blast of abjuration magic as a 60ft cone. All spells of 9th level or lower ends on any object unless the item is an Artifact. All magical items within range lose their magical abilities or traits and cannot regain them unless recrafted as a new magic item. This effect targets magic items regardless of whether they are worn or carried. For the purposes of this spell, a construct and familiar counts as being animated or bound, respectively, by a magical effect, and will deactivate or be banished if within range of this spell. An awakened plant or animal exposed to this spell is likewise no longer awakened. 

If an item is an Artifact, roll a d20. On an 18 or higher, the Artifact loses its power forever and the divine creator of the Artifact knows that you are the one who destroyed their item. The divine creator does not know your location automatically.
