Seiőjarn Shield Master

You use shields not just to protect yourself,  but to protect your team. You gain the following benefits while you are wielding a shield:

• If you aren't incapacitated, you can add your shield's AC bonus to any Dexterity saving throw you or any allies within 5 feet make against a spell or other harmful effect.
• If you are subjected to an effect that allows you or an ally within 5 feet to make a Dexterity saving throw to take only half damage, you can use your reaction to take the saving throw too,, and take no damage if you can succeed on the saving throw, interposing your shield between your team and the source of the effect.
• If you have a Seiőjarn Steam Shield, the radius for the previous effects is doubled, and you can utilize the steam power of the Shield to create a smokescreen that is a 10ft circle up to 20ft away.
