Ok, so you know by now that you can build up your weapons. But the thing is, how do you do it? It's pretty simple to understand but hard to accomplish. All you need to do is make your weapons stats a certian number. Inluding attributes, Atk, Ed, etc., and monster busting stats. You increase these stats with either a broken dagger(see my cheat) gems, or regular attachments. If you are not sure exactly how much you need in each stat, or if you need more points in a certian stat, just go to the weapon, blick the ???? shown after you choose the build up option, and look at what you need. The insufficiant stats are in RED, so you know what to focus on. Hope this helps.
