About this Mod
CobbleBuilds is an addon for Cobblemon that features content related to gyms, such as gym structures, leaders, trainers and badges.


This project is still in alpha. Things are likely to change internally, possibly leading to lost progress or full save corruption. We highly recommend making a world backup before installing or updating the data pack so you can revert changes if things go wrong.

Gym badges are separated into four tiers: Copper, Gold, Diamond, and Netherite. Each unique leader you defeat in a gym rewards you with the next badge tier for that gym.
Each gym has four possible leaders and multiple trainer classes. Which ones spawn at a given time are based on the current trainer rank of the players inside.
Your rank increases with each trainer you defeat. You can check your trainer rank on your trainer card located on the advancements screen.
Trainer parties also vary in scale and difficulty based on the player's current party and trainer rank.
The pack currently includes 12 gyms and 24 gym leaders picked from across the different generations of the Pokémon games.
