Healer
Battle Medic. If you have a Healer's kit, you can expend one use of it to tend to a creature within 5 feet of yourself as a Utilize action. That creature can expend one of its Hit Point Die to regain Hit Points. You may roll the die and the creature regains Hit Points equal to the roll or to your Wisdom (Medicine) Skill Proficiency (or Expertise) bonus, whichever is higher.
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 benefit, you can add 1 to any die roll you make.
