Shield Master

Prerequisite: Proficiency with Shields

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

• You gain 1 level of proficiency with the Push/Shield Punch combat skill.
• If you take the Attack action on your turn, you can use a bonus action to use the Push/Shield Punch combat skill.
• 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.
• If you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you can roll to see if you qualify for a reaction. If you do, you can use that reaction to take no damage if you succeed on the saving throw, interposing your shield between yourself and the source of the effect.
