The Deeplands (dimension)

The deep lands would be a new dimension deep in the planets mantle .you would get there by making two beacon bases one inverted on top of the other with 3 block space between top and bottom on bottom ledge you put one beacon on top one you put another beacon and in between the two you would put a conduit and the portal would activate once you put a piece of redstone dust in the bottom beacon.Now,to enter the portal you would first have to throw a full suit of gold armor into the portal and out would pop special armor which would protect you from the depths pressure if you try to go in without suit you would immediatly die.Once you go to dimension there would be ringwoodite a type of blue rock,deep stone the regular rock there ,deep ores which could be crafted into special armors and tools,deep fire would be like lava but with a reddish hue and would light you on fire quickly,white lava would be common but basically acts like water in this dimension and would not set you on five ,ice 10 (based off real ice 10) would spawn in small chunk and could be used for decorative purposes and could be crafted into throwable projectiles that instantly freeze deep fire or white lava solid into deep stone with white lava or crystaline obsidion with deep fire which could be used to craft better armor,deep shrooms bassically a giant spherical mushroom (based off puffball mushroom)it would explode when you attempt to mine it and would have a chance of leaving behind shroom wood(mushroom wood) and it would plant spores on the ground which would grow into new mushrooms you could also mine them and place them back down.Now you wouldnt be able to mine anything because all your tools are too weak to mine materials here and start taking damage imediatly if you are holding them(overworld tools only),so you have to mine some deep shrooms and hope you get enough  shroom wood to make your tools and and shroom woodaxe  would only trigger the explosive effect for the deep shroom 10% of the time and once you have you deep tools you could mine deep stone and the deep iron then deep diamond now they would have slightly better stats then overworld items but the real thing about them that is better is that when you travel to overworld nothing there can damage your deep tools effectively making them unbreakable .Now you could also farm taco plants because I like tacos and they should be in the game but they can only grow in the deep on ringwoodite ( basically dirt there) .Now the superior thing to deep ores  is you bring them to overworld and smelt them they turn into nine of their overworld counterpart ores.and each ore would give better armor and said aromor would be invincible in overworld.A farmable mob they could add would be the firey blob (a swarm of tiny magma cube type mobs all bound together )and they would fly around like a swarm of bees and attack you,the deep cow  which would be a giant cyan roly poly bug the size of a cow and give you deep meat and deep plate your first armor upgrade of the deep also the breeding item would be rotten flesh ,the infernals a type of fiery wither skeleton type enemy that carries a big hammer and wears armor with a skull on it and when you kill them theres a chance a hammer will drop and hammer does 12 damage base ,and there would be deep coral which would be like regular coral but you can farm it by breaking it and replanting it, also they could add striders (look like water striders the size of horses that are orange and yellow)which could be tamed and ridden across the white lava and red fire without taking damage but would sadly explode if you take them into overworld (not nether though),and thier breeding item would be deep cow meat and they would be really fast at moving
