What are the bonuses / penalties for high / low Wisdom?
I know it hinges around experience earned, but does anyone know the specifics? Of particular value would be the level at which you just barely get standard XP (for non-clerics / people who will level up quickly anyway); also, the kind of bonus you get for 18 Wis.
Flip to the back of your BGII manual and you will see that high wisdom gives you a bonus to your saving throws against magical attacks. Inversly, low wisdom gives you a penalty. Your wisdom can also give you a lore bonus or penalty.
