Daerica's Celestial Pyre

This spell can only be cast during nighttime, in full view of the sky. You touch the corpse of a humanoid that hasn’t been dead for longer than 8 hours. As the spell finishes, the corpse is dissolved into a glittering mist and begins floating up towards the sky, forming a star constellation of your own design. You can choose to have the constellation you create be visible to only you, or up to 10 creatures of your choice.

A corpse that has been transformed into a constellation is protected from decay and cannot become undead. The spell also effectively extends the time limit on raising the target from the dead, since days spent under the influence of this spell don't count against the time limit of spells such as revivify or raise dead.

Any creature that can see the constellation can cast a spell meant to resurrect a creature, targeting the constellation instead of a corpse and ignoring the required range for the spell. The creature whose corpse was transformed into a constellation then returns to life as per the rules of the spell used to resurrect it.
