Claymore of the Great Badger

This weighty blade carries with it the strength of the mighty badger. You gain a +1 bonus to attack and damage rolls made with this magic weapon. The sword has 3 charges and regains all expended charges daily at dawn. When you hit a Large or smaller creature with this weapon, you can expend 1 charge from it to push that creature 5 feet away from you.

Heavy: Creatures that are Small or Tiny have disadvantage on attack rolls with heavy weapons. A heavy weapon's size and bulk make it too large for a Small or Tiny creature to use effectively.

Two-Handed: This weapon requires two hands when you attack with it.
