Dire Cursebearing Weapon

Weapon (any), legendary (requires attunement)

This weapon is etched with glowing archaic symbols that form a dire curse upon the foes of the wielder.

Once per round when dealing damage, you may trigger the curses inscribed on the weapon. The target must make a DC 16 Wisdom saving throw or be affected by the spell Bestow Curse cast as a 7th-level spell.
