Warhammer Master (UA)
You master the warhammer. You gain the following benefits:
• When you hit a creature with a warhammer, the creature must succeed on a Strength saving throw (DC 8 + your proficiency bonus + your Strength modifier) or be knocked prone.
• In addition, you can use your warhammer to knock away a foe’s shield. If you hit a creature that’s using a shield, you can have the attack deal no damage and force the creature to drop its shield.
