Crimson Wall Sign

Overview

Crimson Wall Sign is one of the 12 variants of this shape in the game. What changes between them is the material, and with it the hardness, the drops, the durability and the recipe — so every figure on this page is this variant's own. Oak Wall Sign is the same shape in a different material.

Crimson Wall Sign counts as a Nether block in Minecraft 1.21.4. It is available only in Creative mode or through commands. At a hardness of 1 it takes a moment to break but never slows a build down.

Any tool works, and so do bare hands. What you actually collect is Crimson Sign. It is transparent, which matters when you are managing light levels.

With a blast resistance of only 1 it will not survive an explosion. Nothing on the crafting grid is made from it.

About the crimson set

Crimson is not wood at all — it is fungus, harvested from the huge crimson fungi that grow on nylium in the crimson forest — and that biology gives the whole set its defining property: crimson blocks are completely fireproof. They will not burn, fire will not spread across them, and lava will not set them alight, which makes crimson and warped the only sensible building materials anywhere near lava or in the Nether generally. The set covers planks, stairs, slabs, fences, gates, doors, trapdoors, signs, hanging signs, buttons and pressure plates, but there is no crimson boat, because a stem is not a log. Crimson stems strip with an axe like a log and the planks are a deep maroon-red found nowhere else. Bone meal on crimson nylium grows a new huge fungus instantly, so the set is fully renewable from one nylium block.

How long it takes to break

Crimson Wall Sign has a hardness of 1. By hand that is 1.5 seconds per block; with the correct tool at netherite tier it is 0.2 seconds.

You are looking at 0.25 seconds on iron and 0.2 on diamond — the iron step is where the time actually falls.

Nothing here needs a minimum tier: whatever you swing, the block still drops, and the only difference is how long it takes.

The Efficiency formula is level² + 1 added to tool speed — at V that is about 4 times the unenchanted rate.

Tool	No enchantment	Efficiency III	Efficiency V
Hand	1.5 s	1.5 s	1.5 s
Wooden	0.75 s	0.15 s	0.1 s
Stone	0.4 s	0.15 s	instant
Iron	0.25 s	0.1 s	instant
Diamond	0.2 s	0.1 s	instant
Netherite	0.2 s	0.1 s	instant
Golden	0.15 s	0.1 s	instant

Properties

Crimson Wall Sign has a blast resistance of 1, so any explosion nearby destroys it. It lets light through and emits no light of its own. An axe is fastest here; any other class mines it at bare-hand speed, because the bonus only applies to the class the block is tagged for. Broken normally it drops Crimson Sign rather than itself; Silk Touch is what returns the block, and Fortune raises the ordinary drop instead.
