About this Mod

RZ Gyms, also known as Ranzio Gyms, is a progression-focused sidemod for Cobblemon. It adds a custom trainer challenge built around gyms, leagues, badges, and high-difficulty battles.

The mod is designed as a long-term PvE challenge. Players begin with four gym leaders, then progress into stronger league stages: the Nether League, the End League, and the Distortion League. Each stage is harder than the last, with later battles using more competitive teams, doubles formats, Legendary Pokémon, Paradox Pokémon, Mega Evolutions, G-Max forms, Z-Moves, and custom Mega Pokémon from Zamega.

The mod also includes league progress tracking. Defeating league members advances your progress, and completing a league awards its badge. If you lose during a league challenge before earning that league’s champion badge, your progress for that league is reset, so you must defeat its members again.

This mod requires Cobblemon and is built to work with Radical Cobblemon Trainers, Mega Showdown, and Zamega. It is not intended to be used as a standalone mod.

Current progression includes:

-Four initial gym leaders

-Nether League

-End League

-Distortion League

-Custom trainer teams and skins

-Badge and league progress tracking

-Singles and doubles battles

-Mega, G-Max, Z-Move, Paradox, Legendary, and custom Mega-focused teams

Frequently Asked Questions

RZGYMS server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is RZGYMS compatible with fabric?

RZGYMS officially supports fabric for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with RZGYMS – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if RZGYMS consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
