Shield Combatant

Your practice with a shield has allowed you to see it not just as a mere implement of defense from enemy blows, but a versatile implement for both defense, and offense when the situation demands it. As a bonus action, you can forgo your shield's AC bonus to impose one of three effects on a creature within 5 feet.

• Slam the shield into the enemy, dealing 1d4 bludgeoning damage, and impose disadvantage on their next attack roll
• Charge a creature, gaining an extra 10 feet of movement if needed, and granting you advantage on an attack roll against them on your next turn.
• Bash your shield with your main hand weapon, causing a disruptive sound that imposes disadvantage on concentration saving throws for all creatures within 20 feet.

You add your strength modifier, and proficency bonus to the attack roll for your shield, and the strength modifier to the damage.
