Combat Medic

You are adept at healing allies in the midst of combat. You gain the following benefits.

• You have proficiency in Medicine checks.
• As an action, you bandage a willing creature (you may choose yourself) and allow it regain lost hit points by expending its own hit dice at a cost of 2 to 1 (example: a creature expending 4 hit dice will be able to roll 2 of them for healing).
• As an action, you may expend 2 of your own hit dice to achieve the effect of the Spare the Dying cantrip.

You may use this feature a number of times equal to half your character level rounded up per long rest. Normal hit die recovery rules apply to all expended hit dice.
