Punchdrunk Punters Brass Knuckles

Push (Mastery): If you hit a creature with this weapon, you can push the creature up to 10 feet straight away from yourself if it is Large or smaller.

These beat up and well worn weapons smell as if they've spent a week at the bottom of a forgotten cask in a busy tavern. You gain a +1 bonus to attack rolls and damage rolls made with this magic weapon. Each time you deal damage to a creature, it gains one Toxin Point for 1 hour, to a maximum of 10 Toxin Points. As a Magic action, you can cause a creature you can see to take 1d8 Poison damage for each Toxin Point it has, then it loses all Toxin Points.

Light: A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.
