Divine Aid

Choose one creature in range that you can touch. That creature can spend a Hit Die to regain hit points equal to 1d4 + your spellcasting ability modifier. This ability does not work on undead or constructs. The target must be willing and conscious. If the target is unwilling or unconscious, this spell fails. The target can spend an additional Hit Die when you reach 5th, 11th, and again at 17th level. For each Hit Die the target spends, it regains hit points equal to 1d4 + your spellcasting ability modifier.
