Disrupting Weapon

This spell makes a melee weapon deadly to undead. Any undead creature with hit points equal to or less than 200 must succeed a Wisdom saving throw or be instantly destroyed if struck in combat with this weapon. The Magic Resistance trait does not apply against this spell's destruction effect. Undead creatures with legendary actions are not destroyed by this spell, instead they take an additional 8d6 radiant damage or half as much on a successful save.
