Ah, didn't realize there were crafting recipes for it, I didn't really pay attention to the rings/belts because they typically only offered a single stat point and maybe telekinesis or some crap.
Anyway, it's not like you are using charisma to skip any real challenge in the game. Most fights, especially the difficult ones, can't be skipped. All talking really does is let you skip fights you could have easily won anyway.
The whole point is that it's ridiculous that you should get LESS reward for GREATER investment. By putting time and effort into managing skills like charisma, or going out of your way for some extra quest solution, if the ultimate "reward" is less than simply fighting your way through an easy battle, the system is broken.
