*shrug* If there were a ton of things that required massive Charisma abuse to even afford at all, players would complain that there wasn't enough money in the game and that you "need" to abuse the game mechanics to afford stuff.
Somehow I think this is the less-annoying outcome.
Eh, is it really abuse if my sorc needs 20 cha anyway and I didn't even realize it was the tadpole power that buffed all my speech skills to +13.
Second playthrough gonna be sorc again though cos I need one with shield proficiency.
