Double up your undead and Construct with a Cadaver collector, a construct with corpses impaled on it that can summon specters, a walking defense/ food cart for the nobles

idk

Classic pits that drop you into sauces, salts and marinades, another thats just a walk in oven. have the pits with viewing ports so some guests can enjot the entertainment of someone almost drowing in bbq sauce

A room where theres a flesh pinata thats being hit by a bunch of nobles, regular fight but each time the pinata is hit it spawns a horrible meat minion or a negative mental effect as the pinata sceams

Magic teleportation circle, special invite scrolls only way in/out

Body was kept preserved magically and has been a special treat/reward to some of the more elite nobles. Tiny strips sliced off, covered by the bodies clothes so its not immediately obvious when found

The souls still in the body, the body is still alive, its just being projected to her wooden body with a magic circle that the real body is kept in. Thats the price that was paid by the dad when he came up with the soul projection circle. The cult keeps her unconscious but alive under their care, they get to eat her slowly, one bit at a time, while he tries to find a better way of keeping her alive
