An EXTREMELY OP Mod for 1.12.2 that adds 4 dimensions, the least OP one is the OP Dimension, made up of 4 biomes. The OP Plains and Forest, The Golden Desert, an Irontartica. This is the least op as no mods really use diamonds and minerals in the hardest recipes. The other 3, the sand, gravel, and especially clay dimensions are REALLY OP, ruining ALL MODPACK BALANCE as you dont need EFFORT to obtain them
