Brothers in Arms
General Feat (Prerequisite: Level 4+, At least two characters each taking this feat)
Sometimes, combatants, through experience, form a bond baptized in fire.
Each partner gains the following benefits.
Ability Score Increase. Increase any ability score by 1, to a maximum of 20.
Back to Back. While fighting side by side with 5 feet of each other, an enemy can't gain any benefits by flanking either of you.
In addition, when you are hit with an attack, one of the partners who has this feat may use a Reaction to switch places with his partner and become the target of the attack instead. If the attack missed the new target's AC, it missed. Otherwise, it deals damage normally to the new target.
Mind to Body, Body to Mind. While fighting side by side within 5 feet of each other, you may use a Reaction to provide your partner with your own saving throws modifier instead of their own, as you aid each other physically and mentally.
Like the Back of my Hand. While you are within 30 feet of each other, your familiarity allows you to provide each other with the help action as a Bonus Action. Only one of you can use this Bonus Action during the same round.
