Battle Couple

You have had so much experience fighting side by side with your battle partner, its like you can guess what they are going to do. As a result, you gain the following:

• Two characters with this feature can fight from the same space and gain a +1 to hit & AC while doing so
• When you are within 10 feet of your partner and they make a successful attack roll, you can use your reaction to make an attack against an enemy within range
• When the battle couple is within 10 feet of each other and both partners are subjected to the same saving throw, either partner may reroll a failed save, so long as one succeeds. Whoever rerolls must use the second roll.
