Tiebreaker

In battle, many strikes end in ties, most giving you the short end of the stick. Now, you can have ties work for you.

-When an enemy makes an attack roll that is equal to your AC, you can spend your reaction to give yourself a +1 to your AC until the end of your next turn.

-When you make any saving throw and you fail by 1, you can use your reaction to add a +1 to that saving throw. (If you have the Shield Master feat, a successful DEX saving throw will also trigger that effect in the same reaction.

-When you make an attack roll and miss by one, you can use your reaction to lower the target's AC by 1 until the end of your next turn.

-Only one of these effects may happen at one time.
