In variants with a vampire race, slow digestion should not affect their nutrition clock, in order to prevent them from using it to practically ignore the hunger mechanics as soon as they find a ring.
This could be flavorfully justified as them being undead and therefore not having a digestion process to slow down.
Cooking system in which you apply a knife to corpses to turn them into raw ingredients, then combine them over a hot surface such as a campfire or lava to turn them into food items that are superior to raw corpses, whether that’s by having increased nutrition, conferring temporary slow digestion, boosted intrinsic odds, raising attributes, or other benefits. One specific recipe mentioned is combining a cockatrice’s heart and potion of acid to produce a food that cures stoning and gives temporary stoning resistance.
The lack of cooking gear in the game (other than dented pots) means there might have to be some sort of fixed “cookpot” dungeon feature found at various places which acts like the ones in Zelda: Breath of the Wild; a specific place to combine food items together.
If the cooking system uses fixed recipes, there should be cookbooks containing various recipes so they don’t require spoilers to find out.
One major flaw pointed out with a cooking system is that it has to somehow establish itself as better than merely eating corpses, so it either has to deliver amazing benefits from eating the food or nerf corpse-eating, while still allowing it to be practical to play vegan or foodless. One possibility is to remove most roles’ ability to eat raw corpses (Barbarians and Cavemen could retain this ability as a role benefit).
Artifact horn of plenty that gives slow digestion when carried and never needs to be recharged; however, it never dispenses potions because allowing the player to get infinite potions is obviously not a great idea.
It’s been noted that an artifact such as this makes it so you never need food again, removes that aspect of gameplay, and should therefore probably only appear very late in the game.
