What it does

The mod is a from-the-ground-up rebuild of the original Infernal Expansion, developed by a different team because its final contents deviate from the first release. It adds the Glowstone Canyon biome, with Glowstone stalagmites and stalactites, Shimmer Sand deserts and pits of Glimmer Gravel covered in Luminous Fungus that light up when approached. Dullthorns grow there as prickly plants.

Glowsquitos are firefly-like giant mosquitoes that drain light from nearby Glowstone, Dimstone and Shroomlight, and their drops include Glowdust and Glowcoke. Glowsquitos are neutral by default, but swarms may turn on players who stand around them without Luminous protection. Glowfrogs are clams that swallow Glowsquitos whole, and their tongues knock things away. Slain Glowfrogs can be eaten in a stew.

Infernal Expansion Redux is open source under the GNU Affero General Public License v3.0 only. It requires Geckolib and Lithostitched, and runs on client and server, so the server and every player need it. Builds cover 1.20 – 1.21.1 for Fabric, Forge and NeoForge, with 1.20.1 as the only Forge target. Afterimages and Cloth Config API are optional.

What the author says

Is an in-development rebuild-from-the-ground-up of the iconic Infernal Expansion mod, designed for multi-loader support between both Forge and Fabric on 1.20.1, and NeoForge and Fabric on future versions eventually too. It occupies its own page as it is both being developed by a different team than the original, and…
