Triage

You become increasingly proficient in medicine increasing your medicine checks by 2 and granting expertise in medicine.

Additionally, whenever you take a short rest you can make a Wisdom (Medicine) check (DC15) to fashion makeshift bandages and restore hit points equal to 1d4 + your Wisdom (Medicine) skill. This effect can target anyone who has sustained bludgeoning, piercing, or slashing damage.

If you use bandages you automatically succeed the check.
