Shield Master (Revised)

This version of Shield Master has been revised to add a bonus action attack to the feat, as well as to remove the "targets only you" clause of the feat to make it more universally useful.

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

• If you take the Attack action on your turn, you can use a bonus action to try to shove a creature within 5 feet of you with your shield.
• When you take the Attack action on your turn and attack with a one-handed weapon, you can use a bonus action to make a melee weapon attack using your shield. This attack uses the same ability modifier as the primary attack. The shield's damage die for this attack is a d4, and it deals bludgeoning damage.
• 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.
• If you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you can use your reaction to take no damage if you succeed on the saving throw, interposing your shield between yourself and the source of the effect.
