You’ve trained to use shields not just for protection but also for offense, granting you the following benefits:

• First, increase your Strength score by 1 to a maximum of 20.
• If you attack a creature within 5 feet of you as part of the Attack Action and hit with a Melee Weapon, you can immediately bash the target with your Shield if it’s equipped, forcing the target to make a Strength Saving Throw against a DC equal to 8 + your Strength modifier + your Proficiency Bonus. On a failed save, you knock the target Prone or push it 5 feet away. You can use this benefit only once on each of your turns.
• Suppose you are subjected to the effect that allows you to make a Dexterity Saving Throw for only half damage. In that case, you can use your Reaction to take no damage if you succeed on the Saving Throw and are wielding a Shield, interposing your Shield between yourself and the source of the effect.
