It specifically tells you the presence (and location, where applicable) of cyberware/bioware/gene treatments/nanoware, all dependent on how many hits you roll on the assensing test. I think that seems to be a lot more information than just "lack of aura in X/Y/Z/ body part).

Yeah I'd give a player a break on this one. We should start a side thread for that. Let's get back to selling the undead!

Sure, but emotional and health conditions usually are not criminal. The assorted combat cyberware each sam hauls around is.

On a related note, what kind of threshold do you require to assense that somebody is Infected? "A general diagnosis for any maladies (diseases or toxins) the subject suffers" (3 hits), or something more/less obvious?

Well given Infection re-writes their DNA and re-configures the subject internally and, usually externally I'd say it should either be a single hit or just blatantly obvious.

Late to the party but Desparkle the drek out of them. The way infected are treated in 4th edition is the one part of the fluff that gets under my skin the most and makes me chew nails. I've made a couple of screaming threads over it already.

Oh, and the VtR is no where near as good as VtM. Just saying.

Can't disagree more. VtM is a Great Game, But VtR is so much better.

Only one way to solve this. Rock-Paper-Scissors!

Spock-Bomb?

Detecting DNA changes is higher up the difficulty scale, not lower

I'd say 1-2 hits shows you there's something "wrong", 3-4 that it's some kind of energy-parasite, and higher than that gives you enough accuracy to identify what flavor of vampire you're dealing with (provided you're knowledgeable about vampires, of course).

Well this is getting a bit off track again, but it only takes a single hit on the Assensing test to know whether you're dealing with an awakened or mundane being. Two hits gets you the nature of a specific awakened subject (what type of spirit/spell you're looking at are the examples given in SR4A). I would argue that since all Infected are awakened creatures, you need one hit to separate them in a crowd, and two hits will tell you exactly what kind of creeper you're looking at.
