Concerning the point buy system (as outlined in the DMG):
Normally you get 8's in all stats and then spend points to increase them beyond this. But what if you want a stat that is lower than an 8? For example, I have a character with a 6 wisdom (rolled) which I play as incredibly naive and unobservant, and it's lots of fun. Is there some standard way of actually gaining points by taking a score of less than 8 in an ability? Does anyone have a good house rule for this?
