Hint: Instant pick-pocketing:
Build up FOL and skill points, learn the Pick Pocketing technique, and buy the Bandits glove at Herlie. Use the Private Action at the port of Clik before it is destroyed. After the fortune teller speaks of coming destruction, pickpocket her to get the Mischief item. Then, every step you take will result in items such as FOL, potions equipment, etc. Note: This trick also depends on Dexterity (random chosen talent for your character), unless you build your dexterity level high.

Hint: Easy level gain:
Note: A controller with an auto-fire feature is required for this trick. After getting the LEA metal and return it to Armlock, you will get a N.F.I.D. Go to Fun City and follow the story until reaching the part where you are asked to do some "immense training". Enable the auto-fire on X and allow the game to continue running unattended. Left long enough, about 35 levels can be gained.
