Bubotic Axe (5e Equipment)

Weapon (any axe), very rare (major)

A weaponized chainsaw in axe form, covered in rot and infested with so much plague that the blades have turned into oscillating teeth.

Gangrenous Bite. You have a +2 bonus to attack and damage rolls made using this magic weapon. On a hit, the target must succeed on a DC 17 Constitution saving throw or be poisoned for 1 minute. While the target is poisoned in this way, its AC is reduced by 1. A poisoned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
