Having perfected the art of using your shield as weapon, you are now a disruptive force to be reckoned with.

• Increase your Strength or Constitution score by 1, to a maximum of 20.
• You can use your bonus action to make a unique melee attack with your shield. This attack uses your Strength modifier and deals bludgeoning damage. The attack's damage die is a d4.
• When you hit an enemy with your shield bash attack, you can force them to make a DC14 Strength saving throw or be knocked prone. For this feature to work, the target must be no larger than one size category above you.
