I NEED AN EQUIPMENT LVLING SCRIPT.

I remember having a 2K game that pretended to have this. Obviously, I don't remember the title of the game, but I do remember looking at the event script attached to how the system worked. For one thing, characters did not level up on their own, and equipment was locked. I think it's important to note that. Anyway, each battle earned a certain amount of AP, and with enough AP, various stats went up. Therefore, it wasn't as-so-much that the equipment was getting better, but the character was getting better as a result of using the equipment that was locked onto him/her. Or something like that.

The game formerly known as Breath of Fire - Rebirth (Now just simply called Rebirth.) had a system where spells level up. The game was encrypted, so I couldn't look at how the code worked, but it seemed to me that using a spell so many times causes it to be replaced with an upgraded version of the spell. I'm guessing this is the kind of thing you're looking for in your game?
