Dark Prismarine Stairs — Minecraft block

Overview

Dark Prismarine Stairs counts as an underwater block in Minecraft 1.21.4. Dark Prismarine Stairs is made at a crafting table. Hardness 1.5 puts it in the middle of the pack for mining speed.

Mine it with a wooden pickaxe or better, or you get no drop at all. Broken correctly, it drops itself. Sixty-four fit in one inventory slot.

The recipe calls for Dark Prismarine. A stonecutter can cut it straight from Dark Prismarine, with nothing wasted. Nothing on the crafting grid is made from it.

How long it takes to break

At a hardness of 1.5, Dark Prismarine Stairs takes 7.5 seconds to punch out and 0.25 seconds with a netherite-tier tool of the correct class.

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.

Efficiency adds its level squared plus one to the tool speed, so Efficiency V is about 2.5 times faster than the same tool unenchanted.

Properties

With 6 blast resistance Dark Prismarine Stairs usually goes down to a nearby explosion. It is fully opaque and produces no light. One inventory slot holds 64, the normal full stack. The block is tagged for pickaxes, and only that class gets the speed bonus; everything else mines at bare-hand rate. As furnace fuel it burns for 15 seconds — one and a half smelting operations.
