Description

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.

This weapon is fashioned from infernal iron and traced with veins of hellfire that shed dim light in a 5-foot-radius. Any humanoid killed by an attack made with this weapon has its soul funneled into the River Styx, where it's reborn instantly as a lemure devil.

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

Proficiency: simple, brass knuckles Source: Baldur's Gate: Descent Into Avernus p. 223, Ben Huffman - Pugilist (Third Party)
