Okay! It works as intended then! Just tested it and it works, all good, but I agree that it lacks an explanation. I thought that the Xmove was the erotic attack, but I had no clue of when or how it became available, so maybe the "Incubus blood is whispering" text could be worded differently or explained previously on another version?
Anyways, thanks for the explanation, I'm really liking what I'm seeing.
