Healing

Hit Points can be restored by magic, such as the Cure Wounds spell or a Potion of Healing, or by a Short or Long Rest (see “Rules Glossary”).

Knocking Out a Creature

When you would reduce a creature to 0 Hit Points with a melee attack, you can instead reduce the creature to 1 Hit Point and give it the Unconscious condition. It then starts a Short Rest, at the end of which that condition ends on it. The condition ends early if the creature regains any Hit Points or if someone takes an action to administer first aid to it, making a successful DC 10 Wisdom (Medicine) check.

When you receive healing, add the restored Hit Points to your current Hit Points. Your Hit Points can’t exceed your Hit Point maximum, so any Hit Points regained in excess of the maximum are lost. For example, if you receive 8 Hit Points of healing and have 14 Hit Points and a Hit Point maximum of 20, you regain 6 Hit Points, not 8.
