cRPG is a modification for Mount & Blade II: Bannerlord. 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.
EU Players compete on the duel server in a contest to see who is the ultimate warrior.
Spectators and contestants form a ring around the fighters to watch.
Seen dueling here are Xesta and GTX.
