Cobbled Deepslate — Minecraft block

Overview

Minecraft classifies Cobbled Deepslate as a stone-family block. There is no way to craft it; you have to find it and mine it. A hardness of 3.5 makes it slow going without the right tool.

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

Its main value is as a crafting ingredient: 26 recipes need it, Brewing Stand, Cobbled Deepslate Slab, Cobbled Deepslate Stairs and 23 more among them.

About the deepslate set

How long it takes to break

Cobbled Deepslate has a hardness of 3.5. By hand that is 18 seconds per block; with the correct tool at netherite tier it is 0.6 seconds.

You are looking at 0.9 seconds on iron and 0.7 on diamond — the iron step is where the time actually falls.

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, so a level V tool clears this about 4 times faster than an unenchanted one.

Properties

Cobbled Deepslate 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. Being renewable, it can be produced indefinitely in one world. The block is tagged for pickaxes, and only that class gets the speed bonus; everything else mines at bare-hand rate.

Transparent: No
Required tool: Wooden Pickaxe
Renewable: Yes

Drops

Mined with Wooden Pickaxe, Cobbled Deepslate drops itself.
