It's actually a nifty little thing that goes missed. Using Jeff's "Spy" command, you can view an enemy's stats...and steal an item? It's true. Spy also steals the item from an enemy, if they're holding one. But it does not raise the chances of the enemy holding an item. It can be quite useful in certain cases.
In the Dusty Dunes Desert, after you finish your trip from Threed, there is a big opportunity to gain a good amount of experience points. There's an enemy around known as the Criminal Caterpillar, and though he's hard to find, he'll be worth finding. For just killing him, you gain 30384 exp., while the Bad Buffalo, who gives the 2nd highest amount of exp. Only gives a measly 4108 exp.! And the Caterpillar isn't hard to beat at all. Good luck leveling up!
