Fromm what I understand, one of the big concerns when you hit some of the higher levels, especially after overcapping for London’s Viscera, is maintaining your primary stats. Sources of reduction for these stats are a little rare to come across, but they still exist: The Unusual Wager, Orthographic Infection, opening a Catbox, confiding in the Chandelress. Of course, Seeking, the Nadir, Bottled Oblivion, and Ridiculous Hats can also reduce primary stats, but that’s different.
Now, the Unusual Wager gives you the above warning. And that’s very nice, because it’s kept me from using it while trying to keep my Persuasive up. All these other ones, though, don’t. There’s no indication that a Catbox may drop your Persuasive, that Orthographic Infection can reduce your Watchful, that confiding in the Chandelress will ALWAYS dock your Dangerous a few points. Checking the wiki, it seems there’s no easy page to see what can lower your primary stats, either.
So, I can’t help but feel like it would be a good idea to either have some sort of warning on most actions that cause this sort of loss (which is perhaps a bit unlikely), or to have a user-made compendium of actions that lower stats like this without telling you beforehand. In the event that the first doesn’t happen (likely), I feel like it may be wise to start with the second, and perhaps this thread is as good a place for it as any.
