I didnt see such problem. in my game it works how it should. and im not sure if i reading it right but why should your weapon deal 430 dmg ? press i and look what your basic attack should deal, not on your weapon itself! and then then reduce this dmg with the armor the target have and it will deal the correct dmg. But im just a guy who playing the game since 2 days and using this mod for one day so i can be totally wrong. but you can add me and we can look on this sitauation to be sure you are doing all right
