...well, discovered Adepts and Chicago mix about as well as pouring water on a grease fire.
While my Adept rocked in places like Seattle, Denver, and Berlin, she was not much better than a ganger or grunt in the City by the Lake.
Why?
Well there was this little incident back in the 2050's known as the Bug City/Cermak Blast affair, the fallout from which caused the surrounding area to have an ambient background count of 2 (as much as 4 and even 5 in some locales like former. bug hives). Kind of renders a starting adept rather impotent as most powers and foci would only be in the 1 - 2 range and thus, easily cancelled out. It's not just in the CZ either, but pretty much prevalent around most of the city (the way it sounds, maybe Kenosha, Gary, and Elgin would be "clean").
The way I look at it, among adept circles, Chicago would not be very high on the list of places to visit. As a matter of fact, it would most likely be one of the top places to avoid like the proverbial plague. Who in their right mind would want to go into a place where one's powers and foci are pretty much useless, where there still may be straggler bug spirits and who knows what other magical threats wandering around that suddenly you'd be powerless to deal with?
I went through various build schemes and none really work all that well to even minimise let alone counter the effect. Basically one needs to have a pile of Karma to invest in initiations/bonding as well as resources to get a powerful enough weapon focus (like a Force 6 [42,000¥/18 Karma]) that wouldn't be emasculated once you stepped off the bus or train.
I realise that spellcasters have to deal with it as well, however they have a couple options to help offset the effect that adepts don't.
So if you are ever going to be in an extended campaign in the Windy City, consider bringing in a Merc or Paranormal Hunter with a very big gun, the best armour you can find (make sure it is treated for fire and electricity), and lots of APDS. You'll need it.
Chicago is no place for fancy mystical ninja types.
