This rare biome is usually found near Basalt Deltas. There is a lot of Depth Shale and Sculk here, which means you might encounter the Warden in this biome. It is completely quiet, as there are no mobs or ambient sounds here.
Magmite Forest:
This biome is a counterpart to the Crimson and Warped Forest biomes. It spawns near Crimson Forests, and contains new Magmite blocks, which are yellow wood blocks, wart, nylium and mushrooms. This biome often contains Ghasts, Zombified Piglins, and Piglins.
Magmite Haulm Forest:
This rare and very small Magmite Forest sub-biome contains a new plant block that can be crafted into Gunpowder when combined with Iron Nuggets and Quartz.
These small structures can be found in any Nether biome. They are mainly composed of Blue Nether Bricks, with Cut Depth Shale and Red Nether Brick Fences for decoration. The chest contains a small amount of loot from Bastions, like Arrows, Gilded Blackstone, or even Netherite. A new Armor Trim can be found here.
