Gems Rebuild
by Andy_71
Gems Rebuild, by Andy_71, adds four new gems to the world, each with its own passive ability and visual effects.
What it does
The mod introduces the Aqua, Fire, Wind and Earth gems into a world where players can find and use them. Each gem grants a passive effect, and the gems are meant to be tried out by anyone who joins the world. The mod is also distributed as a data pack, so a world can use the gems without installing a mod loader.
Installation depends on the loader chosen. Files exist for Fabric, Forge, NeoForge and Quilt, all with the same beta-1.0 release dated 2026-09-21, and the mod covers 1.21 – 1.21.11 across twelve release versions. The server must run the mod, while players may leave it out and still join. The code is under the MIT License and the project is not open source.
Key features

Aqua, Fire, Wind and Earth gems are added as new items, each with a distinct role in the world.
Passive gem abilities
Holding or wearing a gem applies a passive effect that stays active without any command or action.
Visual effects
Each gem brings its own visual effects, so players can tell which gem is active at a glance.
Data pack version
