Dead Brain Coral Fan — Minecraft block

Overview

Dead Brain Coral Fan counts as an underwater block in Minecraft 1.21.4. It breaks almost instantly, with a hardness of just 0. Anything below a wooden pickaxe breaks it without leaving a drop.

It is transparent, which matters when you are managing light levels. With a blast resistance of only 0 it will not survive an explosion. Sixty-four fit in one inventory slot.

No recipe takes it as an ingredient.

How long it takes to break

Dead Brain Coral Fan sits at hardness 0: 0 seconds per block with your fists, 0 with the correct netherite tool.

The block still breaks with a weaker tool, but below wooden it yields nothing at all — the time is spent and the drop is lost, which is the single most common way players waste a vein.

Each Efficiency level adds level² + 1 to the tool's speed; against a block this soft, instant mining arrives after only a level or two.

Properties

With 0 blast resistance Dead Brain Coral Fan goes down to any nearby explosion. It is transparent to light and produces no light. 64 fit in a slot — a full stack. It is renewable, so one world can supply as much of it as you want. A pickaxe 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.
