Wounds and Non-Magical Healing: A Normal Wound can be removed after a Short Rest with a DC 10 Wisdom (Medicine) check. The check need not be made if a use of a healer’s kit is expended. A Normal Wound heals on its own after a long rest.

A Serious Wound can be similarly healed with a Wisdom (Medicine) check DC 15, or Intelligence (Healers' Kit) DC 15 after a Long Rest. On a failed ability check with the Serious Wound, the afflicted must make a DC 12 Constitution Saving Throw for each Serious Wound. On a success, the wound reduces to a Normal Wound. On a failure, the wound advances to the Critical wound.

Characters can attempt to treat only a single wound per rest.

A few special cases also exist:

Internal Bleeding: Critical Internal Bleeding can be treated in the same manner as a Serious Wound, but the DC of the initial Wisdom (Medicine) check is 15, and if the Constitution check to remove the wound fails, the afflicted dies.

Lungs: A DC 15 Wisdom (Medicine) check, or DC 20 without a healer’s kit, will reduce a Critical lungs wound to Serious, by cutting a new airway. If the check fails, the patient dies.

Leg: A cane can be used to reduce the movement speed penalty of a Standard leg wound to -5 feet. Crutches can be used to reduce the effect of a Serious or Critical leg wound to the same effect as a Standard leg wound.

Wounds and Magical Healing: A lesser restoration spell can, instead of its other effects, remove a Normal Wound, or reduce a Serious Wound to a Normal Wound. Greater restoration can, instead of its other effects, entirely remove a single wound of any severity (but not death). Raise dead removes all wounds that do not cause the loss of a body part. Resurrection and True Resurrection remove all wounds.

Critical Wounds: A critical wound marked as permanent has a 50% chance of being severely broken and needing 30 days to heal the wound (or a Lesser Restoration spell). Otherwise the body part will be considered so damaged that only a Greater Restoration will fix it.
