Nylium

Nylium is a variant of netherrack that generates in the Nether. It has two variants: warped nylium and crimson nylium, each spawning in different biomes.

Obtaining

Breaking

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.

Legend

• incorrect tool, drops nothing
• correct tool, drops nothing or something other than the block itself
• correct tool, drops the block itself
• italicized can be instant mined

Natural generation

Warped nylium generates in the warped forest biome, and crimson nylium generates in the crimson forest biome.

Mob loot

Nylium is dropped when an enderman dies while holding it.

Chest loot

Item	Structure	Container	Quantity	[hide]Chance
Java Edition and Bedrock Edition
Crimson Nylium	Bastion Remnant	Hoglin stable chest	2–7	22.8% { "item": "Crimson Nylium", "stacksize": "2–7", "chance": 0.22793887963348602, "structure": "Bastion Remnant", "container": "Hoglin stable chest" }

Post-generation

Using bone meal on netherrack that is placed next to or adjacent to warped or 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

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, 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. It decays when covered with snow.

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.

Fungi can likewise be grown into huge 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 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.

Note blocks

Nylium can be placed under note blocks to produce "bass drum" sounds.

History

[hide]Java Edition
September 28, 2019							Crimson and Warped nylium is announced at MINECON Live 2019.
							Then they use a planks sound.
1.16			20w06a				Added nylium.
			20w07a				Warped nylium now has a 1⁄109 (~0.92%) chance of being offered by piglins when bartering, in a stack size of 1, making it renewable.
			20w09a				Warped nylium now has a 5⁄226 (~2.21%) chance of being offered by piglins when bartering, in a stack size of 1–5.
			20w10a				Warped nylium can no longer be obtained by bartering with piglins, making it no longer renewable.
			20w12a				Nylium can now be fertilized with bone meal to grow crimson roots, warped roots, fungi and nether sprouts.
			20w16a				Crimson nylium now generates in chests within bastion remnants.
			20w22a				Nylium now drops netherrack, unless broken with Silk Touch, in which case it drops itself.
1.16.2			20w27a				Mushrooms can now be placed and grown on nylium at any light level.
[hide]Bedrock Edition
1.16.0			beta 1.16.0.51				Added nylium.
							Nylium can be fertilized with bone meal to grow crimson roots, warped roots, and fungi.
			beta 1.16.0.57				Crimson nylium now generates in chests within bastion remnants.
