Uncanny Chef

You summon a humanoid individual in immaculate white chef's garb, carrying on their person a set of top-notch culinary knives and miscellaneous other small cooking tools. Their gender, body form, race, and other physical characteristics vary from caster to caster, becoming fixed at the point of the first casting, and remaining the same thereafter. This individual, for the duration of the spell's effect, or until they complete their task, will create for you a marvelous mystic meal from the meat of a recently-killed (within the last hour or less) magical creature or magic-using sentient being. When their meal-creation task is complete, they will present the meal dish to the caster, bow with a flourish of their (very sharp!) tools, and return to wherever it is that mystical eldritch chefs with weird arcane cooking prowess come from. Whatever portion of the killed creature's body that was not used in the dish, will rapidly disintegrate, utterly destroying it.

The caster may opt to eat the meal or discard it. If left untouched for an hour, it will rapidly disintegrate, utterly destroying it. Only the caster can eat the meal; any others attempting to consume it must roll DC 15 to save vs. poison. Failure to save will inflict 2d6 poison damage and crippling cramps for 1d4 hours. Saving will inflict 1d6 poison damage and crippling cramps for a single hour.

Only one meal's effects can be active at a time - that of the last-consumed meal. Any prior unexpired meal effects will terminate immediately upon starting a new mystic meal.

Casting the spell at a higher level allows the caster to combine effects (where applicable based on the supplied meat) up to a maximum of four simultaneously-active effects from a given meal.

Choose from the following possible effects, which are active for up to 24 hours or until the end of the caster's next long rest, whichever comes first:

Attribute Absorption. If the killed creature's ability score for an ability was higher than the caster's, the caster may temporarily gain the bonus corresponding to the killed creature. For example, if an eldritch meal is made from the meat of a creature originally having 15 CON, and the caster has only 12 CON, until the effects fade, the caster can claim the +2 bonus instead of their typical +1, for the purposes of CON saves and checks.

Vitality Absorption. If the killed creature's HP score is greater than the caster's, the caster may temporarily gain the difference between their HP (up to a maximum of 20) as their new maximum HP level. Note that this will not heal any existing damage; if the caster had taken 2 HP of damage prior to consuming the meal, even though their new maximum HP will temporarily now be up to 20 points higher, they are still missing those 2 HP until healed via other means.

Arcane Ability Absorption. If the killed creature had any inherent abilities, for the duration of the meal's effect, the caster gains the ability to use those abilities in the same manner as the original creature, at half potency. Consult the GM for guidance about how to manifest abilities that are also associated with specialized body parts to determine how those abilities manifest on the caster, if the caster does not possess a corresponding body part compatible with the ability. Example: If the killed creature can fly at a rate of 40 feet per turn, the caster can fly at a rate of 20 feet per turn, but the GM may opt to specify that the caster sprouts wings (which may or may not be compatible with any armor they are currently wearing). If the creature could become invisible for 8 turns, the caster can become invisible for 4 turns, and so on. Similarly, any magical attack abilities inflict half the damage they would have.

Arcane Capacity Absorption. If the killed creature had any spell casting abilities, half of the spell slots of each level are now available to the spell caster to expend in spell casting (round up to the nearest 1).

Exceptions: If the recently-killed being does not have any meat of their own and the summoner does not have an alternate fresh meat source available, the spell will fail and nothing will be produced.
