Derive Sustenance

You convert a corpse you touch into useful nutritious material. When you touch one Small beast corpse or one Small or Medium humanoid corpse, it is slowly wrapped in silk over the 1 minute cast time of this spell. If your concentration is broken or you move more than 5 feet away from the corpse during this time, the spell fails and the spell slot is wasted. At the end of this time, the corpse shrinks to a fist-sized package of silk, while any magical or inorganic material is pushed out onto nearby unoccupied spaces. Any creature can use its action to unwrap the silk and consume its contents or feed them to a willing creature. The meal contains enough nourishment to sustain a creature for one day, and restores 2d8 hit points plus additonal hit points equal to the consumed creature's challenge rating (rounded down, minimum of 0).

You may have a number of silken packages created with this spell equal to your spellcasting ability modifier (minimum of 1). If you create a new one over this limit, the oldest one disintegrates.

When a creature that cannot cast this spell consumes one of the silken packages, it must make a DC 10 Constitution saving throw or vomit and gain no benefits from the spell.

When you cast this spell using a spell slot of 2nd level or higher, the amount of hit points restored increases by 1d8 for each slot level above 1st.

With a 3rd level spell slot or higher, you may affect one Medium beast corpse.

With a 5th level spell slot or higher, you may affect one Large beast or humanoid corpse.

With a 6th level spell slot or higher, you may affect up to one Huge beast, humanoid, or giant corpse, or up to three Medium or Small ones simultaneously. When you affect multiple corpses at the same time, you create only one meal, and combine their challenge ratings together to determine the additional hit points restored.
