Paranoia, the game where every character is technically engaged in a crime punishable by death at basically all times, and you’re given a number of clones because you are expected to die…a lot. Also the R&D gadgets, like the personal disintegrator which does exactly what it says on the tin - disintegrates your person.




My answer in that case is “You detect no aura” from the non-magical chowder (or maybe they do detect one if it was flavored with prestidigitation), unless it’s an edition where the effect is a cone, and they are sitting across the table from their friend blinged out in magical gear, in which case they are definitely detecting an aura. Several of them. And they’re going to have to take time, focus, and make checks to recognize that none are coming from the chowder.
