Warhammer Mastery (5e Feat)
From D&D Wiki
Prerequisites: Proficiency with Warhammers
You have learned to let the power from your warhammer increase your effectiveness in combat.
- Increase your Strength score by 1, to a maximum of 20.
- 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 instead force the creature to drop its shield. On a Critical Hit, you can destroy part or all of the shield making it unusable for the duration of combat.
