Medic.

You’ve developed the skills necessary to hold your own in medicine. You gain the following benefits:

• 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.
• Expertise in medicine
