Temporal Salvation

You place a temporal ward on yourself through the crystal ring used in the casting of this spell (which is tethered to an alternate version of you). If you die, you vanish and reappear in an unoccupied space within 5 feet of the space you left (or the nearest unoccupied space). You have a number of hit points equal to half your hit point maximum. If your hit point maximum is lower than that, your hit point maximum rises to half of your total. If you have any levels of exhaustion, they are removed. If you are missing any body parts, limbs, or spell slots, you regain them.

Once you die, the ring turns to dust and is destroyed, and the spell ends. Also, the spell ends on you if its material component is ever not on your person.
