Here is where i upload my own created mods for Disciples 3 Resurrection. These mods sould also work for the normal Disciples III.
This mod adds 4 new heros to hire. Wich are: A Peasant who wants to be a hero, an old Orc veteran, a freelancing Troll and a Snowwolf with magical abilites. Extract the content to your game folder, and again, backup the profiles folder inside the resources folder incase you want to revert back.
