Rallying Banner

Your banner waves high, reminding your allies that the fight can still be won. You restore (4 + ((your level − 8) ÷ 2, rounded down) (minimum 4))d6 healing Hit Points to each ally within the aura of your commander's banner. This healing increases by an additional 1d6 at 10th level and every 2 levels thereafter.

Since this healing relies on drawing from your allies' morale and adrenaline, the healing it grants is halved when used outside of combat.
