You may use a bonus action to perform an act of healing. This is the Quick Patch in which you apply a bandage to any living target within touch range and heal by 1d4 + your Wisdom Modifier. This increases to 1d6 at 4th, 1d8 at 6th, and 1d10 at 8th tier. You may only use this feature a number of times equal to your 2 x your proficiency bonus, and regain all uses upon completing a long rest.
You may add any number of Treatment Dice to this healing.
