Back to Back

Prerequisite(s): Proficient in Perception

After much practice, you and an ally have become adept at fighting in close proximity to one another.

• While you are adjacent to an ally and a creature would gain advantage on a melee attack against you, as a reaction you can negate that advantage.
• If you are adjacent to an ally who is threatened by two or more opponents and either of those opponents would gain advantage on a melee attack against them, as a reaction you can negate one opponent’s advantage.
• As a bonus action you can grant both yourself and your ally a +1 bonus to Armor Class against all melee attacks until the beginning of your next turn.
