Rad Gyms [Cobblemon]
by Gitoido
Rad Gyms, a Cobblemon add-on, places roguelike gym challenges into the world, with entrances styled as Cobblemon ruins.
What it does
Rad Gyms builds on the Cobblemon NPC system and runs its gym encounters through the RCT Api. Each gym uses a randomly generated team, with the strength of its members scaled by base stat total. Entrances appear as ruins in the world, and the mod includes gym configurations for every elemental type.
Gym keys are added dynamically based on the configurations that are available, and they appear in the creative tab. An exit rope lets a player leave a gym instance, and Poke Caches can be configured with datapacks. Rad Gyms is open source under the GNU General Public License v3.0 only, and it is published for Fabric and NeoForge for 1.21.1, with the latest file dated 2026-09-17. Cobblemon is needed on both sides, and the RCT Api is required as well.
Key features
Roguelike gym instances
Each gym is a run with a generated team, so the challenge differs from one attempt to the next.
Cobblemon ruin entrances
Gym entrances are placed in the world styled as Cobblemon ruins, marking where a challenge begins.
Elemental gym configurations
Typed gym configurations come with the mod, one per element, ready to use without extra setup.
Dynamic gym keys
Gym keys are generated from the configurations that exist, so new elemental types appear without manual key lists.
Exit rope
A rope lets a player leave the gym instance at any point during a run.
Datapack-configurable Poke Caches
Poke Caches can be set through datapacks, changing what they hold without editing code.

What the author says
Usually, when it comes to gyms in pokemon, you can notice one thing: they are static. The initial vision was to add randomness, and by design, replayability. But, what if we can do more than that?
