Healer Origin

Able Physician. You have proficiency with healer's kits.
Battle Medic. As an action, you can use a healer's kit to tend to a creature within 5 feet of you. That creature can expend one of its Hit Dice, and you then roll that die. The creature regains a number of Hit Points equal to the roll and \(1d6\) plus your proficiency bonus. The creature can't regain hit points from this feature again until it finishes a short or long rest. Healing Rerolls. Whenever you roll a die to determine the number of Hit Points you restore with a spell or with this feat's Battle Medic feature, you can reroll the die if it rolls a 1, and you must use the new roll.
