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 :)

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.
