Frost incursion biome

this is just a fun idea on how to make an interesting and rewarding frozen nether biome that also maintains the nethers threatening and creepy nature.

I was inspired by the pale gardens immense contrast when making this biome, my idea is the following:

a new rare nether biome called the frost incursion all lava generated withing this biome is replaced by a type of stone called "ancient obsidian" both implying that the biome cooled incredible quickly and that the biome is ancient.

the biome itself is composed of large flat plains occassionally broken up by towering spikes of ice covered in small caves, inside these caves valuble reasources can generate, glowing ice, frost shards, and small abandoned camps that can spawn with chests.

however this biome wont be easy to navigate, for one the ground of the biome is cold so cold that unless the player wears leather boots they will take damage from walking on it and the air is no different unless the player wears a leather chestplate they will start to freeze to death. to top this off the whole biome is covered in a perpetual snowstorm that slows the player down and knocks elyta wearers out of the air.

the biome spawns a dangerous hostile mob (some form of ice zombie enderman) which stalks the player from afar gradually getting closer to them but teleporting away when seen. if the mob gets close enough it will attack the player. the mob itself could drop a useful rare item.

anyways thats my idea i just though it was fun.
