Are you sure about that? Doesn't sound accurate to me. I thought it had an effect on possible morale failure in combat (low cha in a leader thus undesirable) and party members were more likely to break out into arguments if a leader had low charisma.
Hmm, I also know that in IWD2 it effected spell modifiers and bonus spells for priests (being 3rd edition). I would have thought it would also be the same in BG, but don't have it installed to check.
