About this Mod

Overview

Cobblemon Effectiveness is a simple client-side mod for Cobblemon that helps trainers make better battle decisions.
Whenever you enter a Pokémon battle, the mod shows a clean, compact UI overlay that highlights which move types are super effective against your opponent’s active Pokémon.

No more guessing type matchups – see ×2 and ×4 effectiveness at a glance!

Frequently Asked Questions

Does Cobblemon Effectiveness need to be installed on the Minecraft server?

No. Modrinth marks Cobblemon Effectiveness as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Cobblemon Effectiveness require?

Use a file for fabric, neoforge and your exact Minecraft version. Supported versions include 1.21.1. Files for different loaders are not interchangeable.

Cobblemon Effectiveness is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
