Nether Geodes
by VirtualSofia
Nether Geodes adds Amethyst Geodes to the Nether, with a rarer variant that contains a new Black Calcite building block.
What it does
The mod generates geodes in the Nether, following the same layout as the overworld geodes but with calcite swapped for Black Calcite. The rarer Nether Amethyst Geodes contain the new Black Calcite block, which is intended for building. Because the geodes generate on their own, the mod suits packs without normal overworld generation, such as skyblock worlds. Files are published for NeoForge 1.21.1 only, with version 1.0.1 dated 2025-11-09, and the mod runs on client and server under a custom license that is not open source.

What the author says
Adds rarer Amethyst Geodes to the Nether, containing new Black Calcite, a great building block. These geodes have the same design as the voerworld geodes with the calcite replaced with black calcite. Great for packs without normal overworld generation like skyblocks.
