Blade-Eating Battleaxe

Weapon (battleaxe), very rare (requires attunement)

This +1 battleaxe is made of adamantine, allowing it to be used to destroy the weapons of your foes.

Whenever you make an attack action against a creature, you can instead choose to target the weapon of an adjacent creature. The Armor Class for this attack is the same of the creature wielding the weapon. If you hit and the weapon is nonmagical, it is broken and attacks with it have disadvantage. If the wielder of the target weapon succeeds on a Dexterity saving throw (DC 8 + your Strength modifier + your proficiency bonus), the weapon is not broken. If the target fails this saving throw by 5 or more, their weapon is destroyed.

Epic Attunement. You can attempt to break or destroy magical weapons as well, but your attacks against them have disadvantage. Legendary items and artifacts are immune to this effect.

As an action, you can make attempt to smash the weapons of all enemies adjacent to you. Make an attack roll against each target, and if you hit each target must succeed on a saving throw as above or have their weapon broken or destroyed. You cannot use this ability again until you complete a long rest.
