ShoveYou can use this weapon to Shove with the Athletics skill even if you don't have a free hand. This uses the weapon's reach (if different from your own) and adds the weapon's item bonus to attack rolls as an item bonus to the Athletics check. If you critically fail a check to Shove using the weapon, you can drop the weapon to take the effects of a failure instead of a critical failure.
