World depth
by RoyalDevs
World depth extends the Overworld downward below the usual bottom of the world, adding new ores and a new workstation for working materials.
What it does
The mod lowers the world's floor to -256, so generation continues well below the vanilla limit. Its ore generation places new ores in the deeper stone layers, and the ores it adds are separate from the types already present in stone. Cave generation is also changed: a new cave generator produces larger caves that stretch from the surface down to -250, reaching lower than the vanilla cave layers.
A new workstation called the Energizer lets players make new alloys and energize materials, which gives them new properties such as potion effects. Materials, armor and tools made from these outputs are then crafted at a separate Tool Station. The mod is distributed for Forge on Minecraft 1.20.1 only, and it runs on client and server, so the server and every player need it. Its license is the MIT License, and the code is open source.
