Aditions
Aditions brings a set of new vanilla-style building blocks to Fabric, including 16 colors of concrete bricks with their slabs, stairs and walls.
What it does
The mod adds concrete brick blocks in sixteen colors, each with matching slabs, stairs and walls, and stonecutter recipes for the concrete variants. Its building blocks keep the look and feel of the base game, so they can be mixed into existing builds without standing out. Only Fabric API is required beside it, and both the server and every player need the mod because it runs as client and server.
Clover fields and potion changes also come with Aditions. A rare Four-Leaf Clover can be placed on the ground, and bone meal makes the clover take on the grass color of its biome. Luck potion variants restore a survival-style use of the potion. Aditions works in singleplayer and on multiplayer servers, and the author says more vanilla-style content will follow in later updates.
Files are published for Fabric on Minecraft 1.21.1 – 1.21.11, and the latest Fabric file is 0.4.2 for 1.21.1, released 2026-10-14. The mod is released under All rights reserved and is not open source.
