Shield Warden

You have learned how to use your shield more efficiently

If you are not incapacitated, you can add your shield’s AC bonus to any DEX saving throw you make against spell effects targeting only you.

As a reaction, you can use your shield to protect your allies.

• When a creature you can see makes a targeted attack against an ally within 5 ft of you, you can use your reaction to add your shield’s AC bonus to your ally's AC. Your AC will be reduced by the same amount until the start of your next turn.
• If you are subject to an effect that allows you to make a DEX saving throw to take half damage, you can use your reaction to take no damage on a successful saving throw.
• If you and an ally within 5ft are subject to an effect that allows you to make a DEX saving throw, you can use your reaction to add your shield’s AC bonus to your ally’s saving throw. Choose how much of the bonus to boost their saving throw by, and reduce your saving throw by the same amount. Whoever succeeds their saving throw will take no damage.
