Customizing weapons?
Each weapon comes with upgrade slots. By using your weapon they gain points. Spend these points on upgrades by asking a npc. There are limitless number of different upgrades. You can choose to raise stats that are bad on your weapon, or choose to power up what the weapon already boasts in points. By doing so, your weapon will become much more powerful, and will be custom made to your own liking. You can also put a spirit inside your weapon, making it into a living being. These are called “EGO WEAPONS”. Once your weapon has enough experience without losing too much durability, you can turn your weapon into a ego weapon by inserting a spirit into it. By talking and feeding your ego weapon, they gain experience points and become stronger. However, dying too much or ignoring its demands might make it angry, and start dishing out crappy damage. Ego weapons glow, and at higher levels can even be incarnated into using special attacks.
