Dusk Cleaver (Patreon)

Weapon (handaxe), rare

This dark iron axe head is shaped like a crescent moon. You gain a +1 bonus to attack and damage rolls made with this magic weapon.

You can use an action to swing the axe at an area of magical darkness within 5 feet of you, making an attack roll against the darkness (AC 10). If the magical darkness was created by a spell, add the spell's level to its AC. If you're inside the area of magical darkness, you ignore the disadvantage normally imposed on this attack roll as a result of not being able to see. On a hit, the darkness is dispelled. If the darkness fills a space that's larger than 60 feet on a side, the darkness in a 60-foot cube originating from you is dispelled instead. Once this property has been used, it can't be used again until the next dusk.

Light isn't the only thing that can banish darkness.
