Diez KO

Type: Knight Online Private Server
Website: diezko.com

Diez KO is a Knight Online project currently in closed beta, recruiting testers to help shape the server before it opens properly. The team frames it as a long-term build backed by regular updates and a planned content roadmap rather than a server that opens and disappears a few months later. Most of the announced work goes into giving players something to do outside the usual grind, with new dungeons, a full gathering and crafting loop, and nation-scale events that carry more weight than they do in the base game. Anti-cheat is presented as an ongoing commitment rather than a launch feature, with the detection targets stated up front.

The closed beta runs on the server the team calls Carnac, and applications to join the testing team are handled through the site. The build is not a straight recreation of an official Knight Online era: existing systems such as nation invasions and the Lunar War are given more importance, and new content sits alongside them.

Server: Carnac
Status: Closed beta, applications open through diezko.com

Monster Stone dungeons: New Monster Stone dungeons add knight adventures against new monsters instead of reusing the existing dungeon set.
Gathering: Mining, fishing and world gathering supply the materials that feed the rest of the crafting economy.
Cooking and crafting: Gathered materials go into new recipes for foods, potions, armor, weapons and Akara accessories.
Nation events: Nation invasions and the Lunar War are given greater importance than in the base game.
Anti-cheat: Detection targets KOXP, TBL manipulation and unauthorized changes to game files, and is updated as new threats appear.
Long-term roadmap: The team commits to regular updates and planned content rather than a short server lifecycle.
