This trick requires a level 3 wizard with Craft Wondrous item and the Fox's Cunning spell. After the wizard's last level up, earn about 1,500 experience points. Then, go into a safe area and craft a Headband of Intellect +6. Once you have the item, have any character who levels up put it on before you enter into the level up screen. In the skills screen, you will have three to four extra skill points. This is significantly helpful if the character's Intelligence is 18.
