Corpsman

You master the physician’s arts, gaining the following benefits:

Increase your Wisdom score by 1, to a maximum of 20.
You gain proficiency in the Medicine skill. If you are already proficient in the skill, you add double your proficiency bonus to checks you make with it.
During a short rest, you can clean and bind the wounds of up to six willing beasts and humanoids. Make a DC 15 Wisdom (Medicine) check for each creature. On a success, if a creature spends a Hit Die during this rest, that creature can forgo the roll and instead regain the maximum number of hit points the die can restore. A creature can do so only once per rest, regardless of how many Hit Dice it spends.
