You may enjoy caves of qud. It is probably the closest to Elona of all the roguelikes I have played. There was one time where I got an item that allowed me to turn inanimate objects into a sentient companion. I accidentally cast it on a stone wall only for the wall to come to life and start following me around. It was incredibly handy when exploring dungeons since I could just swap places with it to block a door or corridor. The whole game is full of weird stuff like that.
