Improved Crystals
by Thumpbacker
Improved Crystals extends the crystals already in the game, such as Amethyst, Echo, and Prismarine, with new items and blocks made from them.
What it does
Crystals that come from vanilla gain new uses. Amethyst, Echo, and Prismarine crystals can be combined into new crystal blocks, and Prismarine Crystals are upgraded so they produce brand new blocks rather than only the old spyglass, recovery compass, and sea lantern recipes. The mod also adds a family of quartz and prismarine walls with a full block set, and polished, solid, and smooth variants that suit building.
Sea Glass is a new transparent block that removes water when it is placed next to water, so underwater builds look clearer. Chime Blocks play soothing sounds that add ambience to a base or a room. The mod is client required and server optional: players need it installed, while a server can run without it. Improved Crystals is open source under the MIT License and is published for Fabric only, for 26.1.2 and 26.2, with 1.1.1 for 26.2 as the latest file.
