Medic Dedication
FEAT 2 trained in Medicine; Battle Medicine
You become an expert in Medicine. When you succeed with Battle Medicine or Treat Wounds, the target gains a circumstance bonus to the number of Hit Points they regain equal to 5 HP at DC 20, 10 HP at DC 30, or 15 HP at DC 40.
Once per day, you can use Battle Medicine on a creature that's temporarily immune due to having already been treated with Battle Medicine. If you're a master in Medicine, you can do so once per hour.
