Cobblemon XP Lock
by Stampede
Cobblemon XP Lock stops selected Pokémon from gaining experience after battles, and a server command toggles the lock for each one.
What it does
The mod is a server-side Fabric addition for Cobblemon. Players can mark specific Pokémon in their party so that wins in battle award them no experience. A command for locking and for removing the lock switches the setting for a chosen Pokémon, and the messages players see can be customized in the configuration.
Cobblemon XP Lock needs Cobblemon, Fabric API and Fabric Language Kotlin to be present in the server's mods folder before it starts. Only the server requires it, so players join without installing anything. Files are published for Fabric on 1.21.1, with 1.0.1 as the latest build from 2026-03-22, and the project is released under the Mozilla Public License 2.0 as open source. The source code, issue tracker and a wiki are public, and the wiki is expected to hold configuration details.
Key features
Per-Pokémon XP lock
A chosen Pokémon in the party stops gaining experience from battles while others in the party continue to level up.
Lock and release command
A server command turns the experience lock on or off, so staff or players can change the setting during play.
Customizable messages
The text shown when a lock is applied or removed can be edited, so servers can match their own wording.
Customizable identifiers
Lock identifiers can be set in the configuration, which keeps locks working with other mods that read Pokémon data.

Who it’s for: Server owners who run Cobblemon on Fabric for 1.21.1 and want to control which party Pokémon gain experience. Players only need the server to run it.
How it compares
Hidden Ability Spawns is server-side only and open source under the GNU General Public License v3.0 or later, for Fabric on 1.21.1, and it changes which abilities Pokémon spawn with rather than experience. Cobblemon ExpLock Reborn is also server-side only, under the MIT License, for Fabric on 1.21.1 and open source, and it covers experience locking in a similar way. Cobblemon Instant-Run is client and server and not open source under the MIT License, so every player must install it.
