A free mod for Mount & Blade II: Bannerlord, by will.

In Drastic Battle, you are a warrior in a battle against other warriors. It’s a simple battle mod that allows you to do a lot of things to the game. The first thing we need to say about this mod is that the gameplay is really amazing. You can fight with other players, and also against computer-controlled warriors. 

The most important change that this mod brings is that you can now change the damage calculation formula for each weapon. You can use the standard one, or you can use the one that you prefer. This change is really important because it makes the game more realistic.
