Nether Expansion
This mod adds several new biomes, mobs, blocks, and even water to the nether
Toxic Wastes
A very acidic biome that has a dangerous radioactive mob in it
Armor
The new tools and armor added in this mod
All The Nylium
I took this screenshot before I added the wet nylium
Wet Forest
A very cold place in the hellscape that is the nether, cold enough that water can be found here, and rather a lot of it
Old Nether
The nether how it was before the 1.14 texture update as well as before 1.16 nether update
Tropical Nether
So are you telling me this used to be the nether before it was hellish?
Incenerated Plains
A biome that used to be filled with life on the verge of becoming a barren wasteland
Acidic Nether
An expansion on the toxic wastes, with two additional biomes to go along with it
Radioactive Walker
A highly dangerous mob that lives in the Toxic Wastes
Volcanic Barrens
A place more hostile than the basalt deltas itself, they are the reason the nether is so hellish
Frosty Lands
The nether when it was frozen, it still has things to be added to it
Nether Desert
A hostile and barren place full of piglins and blazes, if you can't find a nether fortress then maybe this biome will be the one for you
Electric Forest
A pretty magical biome
Nether Jungle
This is actually unrecognizable compared to the nether now
Infected Wastes end biome
I bet you thought I'd leave the end untouched huh
