Warsword is a fantasy mod based on Warhammer fantasy battles game by Games Workshop. This is total conversion of the original Mount & Blade , and it will not work on Warband.
This is my favorite M&B mod, It's the only one I still play. I've played this more than TLD and Star War conquest. It's stable if you read the summary and install it properly. Only a a few minor bug and has a great replay value.
