Martial Spirit p. 60
As you cleave through your foes, each ferocious attack you make lends vigor and strength to you and your allies.
While you are in this stance, you or an ally within 30 feet heals 2 points of damage each time you make a successful melee attack. This healing represents the vigor, drive, and toughness you inspire in others. Your connection to the divine causes such inspiration to have a real, tangible effect on your allies' health.
Each time you hit an opponent in melee, you can choose a different recipient within range to receive this healing.
