You would detect it like any wizard casting detect magic. You would know something is three that is magic and that would be it. Literally know information other than that would be given unless you took the time to appraise the item. Same with the ring.

Cucco has made his ruling, and while I don't see the logical sense in a senior demon being unable to detect a senior demon she would be at least well aware of it not familiar with, the fact that there is no defined system or reference means it really doesn't matter to me.

[@ArenaSnow]I wouldn't consider it an overeacation as far as seeing the pace. Almost half the party knows/suspects him as a deconomic and they just met him today. If this same course were to keep up then he will basically be figured out by page 5 or 6. [/quote]

Did you miss my above text? Everyone is suspect. Everyone. A demon lord in a monk's body who instigated the meeting? A mysterious statue used by cultists (as per demon lord's information)? Two confirmed demons, one of which is an illusionist (though most of the party wouldn't be aware of the fact)? All in a town full of zombies that a "hero" massacred? For all Tony knows, you're just another manifestation of Remus. Trust will not be freely given. It might take until page 5 or 6 until people can draw proper lines on who to trust.
