Maxing Wisdom will result in an extra level, possibly two;
Wisdom - is it worth the skill points?Another way to improve the experience you earn is to do more killing early in the game (you get less experience for monsters at a lower level that you) and leave many of the quests until later (you get more experience at higher levels).
There are two object in the game that can raise you up a level, so if you leave these until late in the game just after you get to a level, you will maximize the experience bonus you get to reach the next level.
