I have only 3 PCs in my game, so their choice of characters for a somewhat balanced party is pretty crucial. They use a 28 point buy system for ability scores. The problem is, they load up on stats like str and dex that have tangible readily percieved benefits, but then always use charisma for the dump stat. They all have less than average charisma (and their other mental stats aren't too good either), which I could tolerate. But then they never take any social cha linked skills to make up for it. How can I best deal with such a brutish undiplomatic party? How could they feasibly get by in normal adventuring with out atleast an ounce of negotiation muscle? I am led to believe they are under the impression they can fight everything and win, but this simply isn't true. I'm not going to make straight up combat the end all be all solution, and I don't feel the need to cut them slack. Should I simply let them reap the rewards (errr realistic penalities) of such tactlessness?
