This is a fork from Stygian End: Biome Expansion,the origin mod has few configs about biome generation and entity spawn,so I made this.
If you are a 1.12.2 modpack maker seeking mods that overhaul the end,this mod will suits you.
Stygian End:Unoffical adds two new biomes to the end dimension and a handful of new ender themed blocks and plants.
Also,this mod allows you to easily configure what biomes will be generated in the end and their weight,for those who want to make the end fancier.
Caves are added to the end,but no new ores added,it makes mining in the end easier for those who using mods like Netherending Ores.
I suggest you to combine this mod with Biome Tweaker so that you can create a new biome and make it generated in the end.
I had gotten all the sources lost by misoperation,I had no idea but to leave this mod closed sources,but you can still feel free to use this mod.
