It works on them as it says, it's control, but I don't get flavour. For example what I'd get is "roleblock 2-shots, killshot 1-shot, self-protect - 1-shot". And if I hit one of them I'd get information saying I can use it again. So I guess it's mix of control and investigation. I didn't want to use it on Cal because I was expecting him to be here and by control I do waste used abilities. I went for UwU to check out if they have suspicious abilities like killshots, rolecrushes, stealing votes, etc, but they died the same night so I wasted it.
