Glowing, intangible arrowheads distinguish these magical arrows from typical ones. Roll a standard bow attack against a target to heal them instead of harm.  

If the target is aware and willing, the attacker rolls with advantage and the target does not include her DEX bonus to AC. Upon a successful hit the arrow is absorbed into that target with a shower of sparks, healing for 1d6 HP instead of taking damage. On a critical hit the target regains 3d6 HP. The arrow vanishes if the attack misses.
