SONG OF RESTWhen you play an instrument or sing during a short rest, you and each ally who can hear you are affected by your Song of Rest. When an affected character spends healing surges at the end of the rest, that character regains additional hit points equal to your Charisma modifier with each healing surge. A character can be affected by only one Song of Rest at a time.
