Excarnate Corpse (5e Spell)
From D&D Wiki
|1st-level Transmutation (ritual)|
|Casting time:||1 minute|
You target the corpse of a Medium-sized or smaller humanoid or beast, that has a skeleton. After concentration on the ritual, the body splits; allowing the complete, connected skeleton to appear lying atop the corpse.
At Higher Levels: For each level the caster is above 5th level, they can excarnate an additional creature.
(This matches the Animate Dead progression, because 2 character levels = +1 spell slot level)
