Join my Discord server for discussion and any support needs. I love to hear what you have to say!

This pack uses the Smithed Crafter library by rx, Nexus, and many others. You do not need a seperate download, it's included in the files. Thanks to them!

This pack wouldn't be possible without the unending support of CreeperMagnet_, rx, Nexus, Delta, the rest of the Smithed community, and all my friends who keep me going. A heartfelt thanks to all of them :)

Frequently Asked Questions

Alchemika server crashes on startup – what to do?

Most common cause: wrong datapack 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 (1.21.11). You can switch loaders with one click in the panel.

Is Alchemika compatible with datapack and fabric and forge and neoforge and quilt?

Alchemika officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.11, 1.21.10, 1.21.9. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Alchemika – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Alchemika 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.
