Wyntir's Mortal Reperation

Touching one unconscious creature the user funnels life force from themselves into their target. Touch one creature with zero hitpoints who is not dead you instantly drop to zero health points as the target is given hitpoints equal to what you lost when casting the spell. The caster does have to make death saving throws beginning their next turn.

When cast with a spell slots of 4th level or higher this spell also works on targets who have died within the past minute bringing them back to life.
