Homemade weapons are now tad stronger than originally manufactured; meaning, for example, that your new Meitou weapon will have reasonably better stats than the ones wielded by in-game characters.

Note: I'm aware that there are similiar mods in existence, but from what I could gather none of them does everything. You need to download a few mods to be able to achieve what this one mod does. This mod was initially made for personal use but I hope that someone else will find it useful.
