The Best Defense

You gain the following benefits.

Ability Score Increase. Increase your Strength score by 1, to a maximum of 20.

Shield Bash. Whenever you take the Attack action or make an Opportunity Attack, you can make the attack with your Shield if it’s equipped. If the Shield provides a bonus to Armor Class beyond its normal bonus, you also gain that bonus to attack and damage rolls made with it. A Shield being used as a weapon has the following traits:

Weapon Category: Simple Melee
Damage on a Hit: 1d4 Bludgeoning plus the ability modifier used for the attack roll
Properties: Light
Mastery: Topple (you can use this property, and it doesn’t count against the number of properties you can use with the Weapon Mastery class feature)
