What it does

ObsidianSlab is a Cursed block mod that adds an obsidian slab in the Technology and Utility categories as well. Client and server both need it, so every player on a server that runs it installs it too. Files cover 1.16.5 – 1.20.1 on Fabric and Quilt, with 1.2.1 for 1.20.1 as the latest build, and the code is under the GNU Lesser General Public License v3.0 only, which makes it open source.

Key features

  1. Obsidian slab block

    Adds a slab made from obsidian that can be placed like other slab blocks in the game.

  2. Dragon egg breaking

    Includes a requested option that lets players break the bedrock block under a dragon egg.

  3. Separate block code

    The block code lives apart from the main mod, so the slab can be examined and reused on its own.
