step further.
Say you gotta pick a certain weapon at the beginning of the game, and as it levels up, you get points which you can use to customize it like you do with your own char.
Obviously you cant get as much as you do with your char, but maybe somthing like you can add 1 skill to your weapon every 5 levels (that means that to get freeze lvl 3 you would need to be 15 before it could be achieved) and like 2 stat points per level.
Now that would be cool! <img src="/ubbthreads/images/graemlins/up.gif" alt="" />
