Grow Your Crystal
by space_lover_
Grow Your Crystal lets players grow their own crystals on Fabric 1.21.8, with colors and effects chosen during the process.
What it does
Players make a crystal seed with a crystal growing toolkit, obtained from piglins who trade or from bastion chests. A seed is placed in water and fed with a crystalline solution, which is crafted from the toolkit using a crystal base made of quartz, amethyst or diamond, plus one or two dyes. The solution needs time to dissolve and form the crystal, and the crystal must stay hydrated while it grows. An optional powdery substance adds its own effects to the result.
Crystals can be grown with customizable colors and properties. Up to three differently colored layers can be added, and layers can give a crystal custom properties, such as making it glow or turning it into a candy-like block. A crystal cannot be moved after it is placed without breaking it, so clusters have to be formed where they will stay. The code is public in a source repository, but the mod is released under a custom license and is not open source. Grow Your Crystal runs on client and server, so the server and every player need it. Files are published for Fabric only, for 1.21.8, and the latest is 1.0.4+fabric-1.21.8.
