They’re Not Hit Points or Healing
Playing the Game > They’re Not Hit Points or Healing
Temporary Hit Points can’t be added to your Hit Points, healing can’t restore them, and receiving Temporary Hit Points doesn’t count as healing. Because Temporary Hit Points aren’t Hit Points, a creature can be at full Hit Points and receive Temporary Hit Points. If you have 0 Hit Points, receiving Temporary Hit Points doesn’t restore you to consciousness. Only true healing can save you.
