Dark Prismarine — Minecraft block

Overview

Dark Prismarine is an underwater block in Minecraft Java Edition 1.21.4. A crafting table turns its ingredients into Dark Prismarine. Its hardness of 1.5 makes it a normal, unhurried block to mine.

Anything below a wooden pickaxe breaks it without leaving a drop. It drops as the same block you mined. It stacks to 64.

You make it with Prismarine Shard and Black Dye. Its crafting uses are Dark Prismarine Slab and Dark Prismarine Stairs.

About the prismarine set

How long it takes to break

Dark Prismarine sits at hardness 1.5: 7.5 seconds per block with your fists, 0.25 with the correct netherite tool.

You are looking at 0.4 seconds on iron and 0.3 on diamond — the diamond step is where the time actually falls.

It will break below wooden, and you will get nothing for it. That combination of time spent and drop lost is the classic mining mistake.

Each Efficiency level adds level² + 1 to the tool's speed, so a level V tool clears this about 2.5 times faster than an unenchanted one.

Properties

Dark Prismarine resists blasts at 6, which usually is not enough when something explodes nearby. Light does not pass through it, and it emits none of its own. A single slot takes 64, the usual full stack. The fastest tool for it is a pickaxe; any other kind of tool mines it no faster than a bare hand does, because the speed bonus only applies to the tool class the block is tagged for.
