This mod adds few biomes in the future it will add few dimensions too okay so back to the point: this mod adds biomes mobs and blocks:

MOBS:

Copper (Coppy) Golem: a cute little robot that has few variants one of thoes is verey dangerous! be careful!

Crimson Blob: a blob of crimson what else to say

Crimson, Warp and Sculk Bugs: these guys are pretty dangerous! if there multiple of them you should start running (not yet fully impemented)

Sculk Cow: a rideable mob

The Watcher: it is a very dangerous foe i suggest avoiding it entirely its ambient sound is the same as a sculk shriekers so

if you hear a shrieker underground it might not be one

Biomes:
Sculk Lands (deepdark in code):

the first biome to ever be added to this mod! it is also one of the most danegours ones

Warp Lands:

same as sculk lands but less dangerous and less finished

Crimson Lands:

same as Warp Lands

a very badly made showcase right here!

Basic crafting:

most of the crafting is very similar to vanilla crafting like armors sword etc. JEI is still suggested
