Double Shield Weapon Master

You use shields not just for protection but also for offense. You gain the following benefits while you are wielding two shields:

• Shields work as light weapons for you.
• If you are wielding two shields, you may benefit from the AC bonus with both shields (max bonus +4).
• If you take the Attack action on your turn with your on-hand shield, you can use a bonus action to make an attack with your off-hand shield.
• If you aren't incapacitated, you can add your shield's AC bonus to any Dexterity saving throw you make against a spell or other harmful effect that targets only you.
