cobblemon server gym league
by thomasszos2
Cobblemon servers that want a structured gym circuit can run one through CobbleLemon Gym League, which adds a server-side league of Gym Leaders, Elite Four members and a Champion.
What it does
Players challenge Gym Leaders to earn badges, then take on the Elite Four and the Champion once enough badges are held. Challenges are fought as automatic Cobblemon PvP battles using Gen 9 singles rules, with configurable battle levels, request timeouts, result broadcasts and challenge rules. Badge tracking, a leaderboard of standings and Elite Four progress are kept by the mod, and seasons reset the progression on a schedule that staff control.
Staff on a server can run the league from an admin screen that handles roles, seasons, badges, arena setup and configuration reloads. Badge definitions and required badge counts are configurable, and arena positions are set so battle starts are clean. Role and group syncing works through LuckPerms, and the Fabric Permissions API is used for access checks.
The mod is for Fabric builds of Minecraft 1.21.1 that run Cobblemon. It needs Fabric Loader, Fabric API and Fabric Permissions API on the server and on every player's client, because the environment is client and server. Files are published for 1.21.1 only, with the latest, 1.1.0, dated 2026-05-23. It is not open source and is released under All rights reserved.
