A small suggestion to mojang
It will not be as small as shown in the images
It will be big
What will be its purpose
It will have unique blocks forming around the craters like asteroid stones or new types of stones called suevite , dead soil, dead plants new yellowish water when mixed with asteroid soil
Spawns a mob inside called murk which has its own new uses drops murk shards to make new types of glass which survives explosion
Cracked stones if carved will have new items such as bone scraps used as an armour trim
New armour trim name scars
New disc named impact
Also the bone scraps can be also used to make a bone sword which is effective against dead mobs including weither
Drop your suggestions
I don't have particular blocks or things to show in those images just pure imagination 😂
