Skill mining

Skill mining would change the way ores spawn to make it less random for instance coal chunks will spawn close by, iron chunks will be far away from other iron chunks and spawn in jungles at a greater rate , gold would spawn close by other gold chunks and at a higher rate in desert and Mesa biomes, diamond would spawn far away from all other diamond chunks yet will usually hide deep in coal chunks and has a greater chance to spawn in snow biomes, Emeralds would spawn far to other emerald chunks and exclusively in mountain or hill biomes also will be surrounded by gravel, lapis lazuli would spawn close to other lapis lazuli chunks near underground generated structures or in underwater caves, red stone will spawn close to other red stone chunks and will spawn near ravines, lava or deserts. This would make ore spawn more realistic and less random making it easier to speed run and more effective to mine in different biomes when looking for different ores.
