Crimson nylium is a variant of netherrack that generates in the Nether.

Obtaining

Breaking

Crimson nylium drops itself only when mined with a pickaxe enchanted with Silk Touch; if mined with a normal pickaxe, it drops netherrack. If mined without a pickaxe, it drops nothing.

Natural generation

Crimson nylium generates in the crimson forest biome.

Mob loot

Crimson nylium is dropped when an enderman dies while holding it.

Post-generation

Using bone meal on netherrack that is placed next to or adjacent to crimson nylium transforms the netherrack into nylium of that type. Air must be above the netherrack during this process. This transformation can also be done by activating a dispenser with bone meal directly into that netherrack block. If both types of nylium are present, there is an equal chance of either being spread.

Renewability

This feature is exclusive to Bedrock Edition.
 

As netherrack generates in Nether portals spawn floating, using bone meal on netherrack turns them into nylium, making them renewable.

Usage

Similar to grass blocks and mycelium, crimson nylium decays (based on random ticks) into netherrack when an opaque block is placed above it. However, unlike grass blocks and mycelium, it does not decay underneath water or lava.[1] It decays when covered with snow.[2]

Like mycelium and podzol, mushrooms can remain on nylium blocks in any light level. Huge mushrooms can be grown by using bone meal on mushrooms planted on nylium.

Crimson Fungi can likewise be grown into huge crimson fungi using bone meal, although the fungus must be placed on the same type of nylium, or the bone meal is never consumed.

Similar to grass blocks, the player can apply bone meal to crimson nylium. This nylium, along with nearby nylium, generates vegetation that occurs in its native biome (crimson nylium generates mostly crimson forest vegetation and warped nylium generates mostly warped forest vegetation), and just like in the native biomes, the opposite type of fungi occasionally generates. The vegetation is generated in a 5×5 area, centered on the nylium block on which bone meal is used.
