To create a new character class, follow the usual procedure and use your points to get whatever you want, but make sure that you buy a load of potions (60 points). When you've spent all your points save the class. Choose cancel and return to the menu to select the class you've just made. If you now go to the equipment menu and deselect your potions, you'll get 600 points for each one! So now you can get loads more stuff.
