Axe Master

You have practiced extensively with axes, gaining the following benefits:

• Your Strength score increases by 1 to a maximum of 20.
• When you score a critical hit on an enemy, it must pass a DC 18 Athletics(Str) save or be knocked prone.
• As an action, you may use your axe to cleave through any nonmagical shield, destroying it to the point it no longer provides a bonus to AC. If the shield is wielded by a creature, that creature can make a Dexterity saving throw, with a DC equal to 8 + your proficiency bonus + your Strength modifier. If it succeeds on this save, its shield is not destroyed.
