Bestial Regeneration

You turn the spent life force of dying creatures into a healing cloud. When a creature takes damage, you may cast this spell as a reaction using that creature as the target. For every point of health a creature loses within 30 feet of the target until the target's next turn, the target will gain that much temporary Hp at the end of it's next turn. This temporary HP lasts until the end of whatever combat the target is in, or a minute, whichever is longer. If the target would reach zero HP before it's next turn, instead of gaining temporary HP, its HP cannot drop bellow 1 until the end of it's next turn.
