Minecraft wiki entry for Nether_survival, associated text: This is the one of the most dangerous biomes. It is definitely not recommended to base up here. Because of the jagged terrain, magma cubes, and lava, it is easily the most dangerous biome to be in. The only benefit of this biome is easy access to magma cubes for magma cream (for brewing fire resistance potions), and easy access to blackstone (used as a substitute to cobblestone), and an easy access to basalt (no usage other than building). Do not build your house inside this biome, but building it close would do no harm.
