Infinite Abyss
Infinite Abyss takes players past the Nether into six underground dimensions, each with its own terrain, mobs and portal key, and three new bosses waiting at the bottom.
What it does
Layers are opened in order through portals. The first portal is built from Amethyst blocks and lit with an Amethyst Key craftable from amethyst. The second uses Deepstone blocks and a Pink Crystal Key, and the third is an ordinary Nether portal lit with Flint Steel. Each layer then leads to the next, so progress builds up from the surface toward the deepest caverns.
The layers are very different from one another. One is a large cavern of stone full of crystals, and another is a reddish stone area of magma that is less hot than the Nether. A fungal layer is filled with mushrooms and mycelium, a layer of prismarine guardians has glowing vines hanging from its roof, and an icy frozen cavern is home to wind spirits and other frozen creatures. The deepest layer is a shadowy cavern of glowing eyes, where a tentacled humanoid monster four blocks high wields a large sword and shoots toxic slime at players.
Installation needs Forge or NeoForge only. A server running it needs every connecting player to have it too. It is published for 1.20.1, and the 1.8.5 release is the latest file for both loaders, dated 2024-11-30. The code is All rights reserved, so the mod is not open source.
Key features
Six underground dimensions
Six layers sit below the Nether, each with its own cavern type, terrain and creatures.
Three bosses
Three new bosses guard the deeper layers, one of them a crystal-block boss that spins and attacks players.
Frozen Wither
A larger, stronger form of the Wither lives in the icy layer.
Portal key progression
Each portal is lit with a key that players craft, which sets the order in which the layers are reached.

How it compares
The Deep Void is open source under the MIT License and runs on Forge and NeoForge, with files for 1.19.2 – 1.20.6. Dive Into the Abyss is also open source, under the GNU General Public License v3.0 only, and covers 1.20.4 – 1.21.3. Infinite Abyss is not open source, is released under All rights reserved, and is published for 1.16.5 – 1.20.1, so it is the option for the older versions.
