I consider this omox demon oracle perhaps one of the most entertaining npcs in the whole AP. In fact changed a bit the first contact the PCs have with her instead of doing as described in the module just for the sake of doing a reference to the Beelzeboss scene from the Pick of Destiny and the song from a certain video game.
However, I would like to know how was your experience with the filthy "succubus" as PCs or GMs.
