New Potion: Splash Mutagen

This is the entrypoint for the mod. Brew this in a brewing stand (glowstone -> spider eye -> gunpowder). Throw it at . . . well, salmon for right now. It only works on salmon. More coming though!

Mutated Creatures

Mutants are typically enlarged mount versions of peaceful mobs. Salmon are a versatile underwater mount. Make sure to bring water-breathing equipment, you might have an underwater mount but you're on your own for oxygen.

Frequently Asked Questions

Mutagen 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 (1.20.4). You can switch loaders with one click in the panel.

Is Mutagen compatible with fabric?

Mutagen officially supports fabric for Minecraft 1.20.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Mutagen – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Mutagen consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
