Well that clears things up
Thanks guys!
makes sense, as my thief that had both security and sneak fairly high never had that much of an issue pickpocketing. however, those d100 rolls means that even with 100 skill, the odds are well against you.
Interesting... What kinds of things are you able to pickpocket in the vanilla? Is pickpocketing, well, profitable with a high enough sneak/security score?
And interestingly enough, the maker of the mod Helena linked reports that it
does do something through his tests... this calls for personal testing
