The Surgeon

Able Physician. You gain proficiency in the Medicine skill.

Battle Medic. If you have a Healer’s Kit, you can expend one use of it and tend to a creature within 5 feet of yourself as an action. That creature can expend one of its Hit Point Dice, even if it's unconscious or dying, and you then roll that die. The creature regains a number of Hit Points equal to the roll plus the total bonus you would apply to a Medicine skill check.

Healing Adept. Whenever you roll a die to determine the number of Hit Points you restore with any healing you can reroll the die if it rolls a 1.
