This would be way down the list, but an option to simply put someone in an Obliette or the equivelent. Basically torture without gaining information, for those times when you just want to make someone suffer. It could do less damage then torture, but be less detectable.
Torture, as it has a use, doesn't convey as much malevolence. As mentioned, there's probably only a few realms that would do so, so it's not an important alteration.
