cRPG is a popular modification for Mount & Blade: Warband. It adds persistent multiplayer character stats, hundreds of unique items, an online campaign, clans, duel ladder, a co-op game mode and a few more things.
Here we see the Serbian Light Cavalryman Armor by Zimke. One of several new items being added to cRPG in a coming patch.
Also seen here are the Rus Cav Boots and Gnezdovo Helm, two items already in cRPG that complement nicely the Serbian Cav Armor.
