Mystery meat

Mystery meat is a food item obtained during the Broken Home quest. It fully restores life points when eaten. Mystery meat can be found in various chests in the mansion, and restarting from your save point also gives you some mystery meat.

If the meat was ever somehow taken out of the mansion, eating it would result in the message: "The rancid taste of the meat shows it has become rotten, so you discard it."

Trivia

 * The meat is currently the best food in the game, although it can only be eaten within the mansion.
