In season 5 mission 3, the background count for the toxic shaman's lair is 1, or 2, depending on where in the lair you are. However, this is supposed to be inside the radiation zone (even if only slightly) and the general background count of the CZ is supposed to be 2 - so one would figure it should go up, not down or stay in place As writted, I would just go with the background count as listed in the mission, but somehow it seems to make more sense to me to add those background counts to the base 2, for a total of 3/4. Of course, that might just be too much and hose mages/adepts too badly.
How have other GMs been playing this?
