...thank you.
Just does not seem as "cost effective" to get a high force QI focus compared to just improving the raw skill considering the constant -2 penalty. Were we in another location where BGC was only encountered now and then, it wouldn't be as much of an issue.
With multiple foci, one also has to consider the greater chance of Focus Addiction as the total force of all foci used is subtracted from the base 11 weeks. For example, with just her WF, KK has 7 weeks before having to make a test, not much of an issue. However, if she also uses a force 4 Qi focus on the same mission, that period is reduced to only 3 weeks so the risk of addiction becomes much greater. Somehow the thought of being addicted to a focus in an area where the effects of magic are reduced and in some cases even nullified, just sounds like a bad combination.
