Based off of the Gentle Repose Spell:
3rd-level necromancy (ritual)
Casting Time: 1 action
Components: V, S, M (one Caldefra Frost Vine Seed)
Duration: 1 month
You touch a corpse or other remains. For the duration, the target is protected from decay and can’t become undead in a block of ice.
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 the spells such as raise dead.
NOTE: Think Han Solo…
