Tasha's Disjunction requires one action and verbal components to cast. The spell creates a 40-foot radius sphere in an area nearby to the caster that causes all magical effects and magic items to become disjoined. Doing so causes all spells and magical effects to end, and magical items that fail to resist the spell are stripped of their enchantments and become non-magical, each permanent magic item must make a successful Wisdom saving throw or be turned into a normal item. An item in a creature’s possession uses its own Wisdom save bonus (when applicable) or its possessor’s Will save bonus, whichever is higher.
Additionally, sufficiently powerful casters have a chance when casting Mage's Disjunction to destroy an Antimagic Field, equal to 1% per spellcasting character level.
Note: Destroying artifacts is a dangerous business, and it is 95% likely to attract the attention of some powerful being who has an interest in or connection with the device.
