Hard Rocks
by Fiosky
Hard Rocks changes mining so that solid stone resists ordinary tools and rewards deliberate excavation, and it is a Fabric mod for 1.21.1.
What it does
Stone and Deepslate found in exposed caves, cliffs and mountains break normally, but the deeper a player digs into solid rock, the harder the stone becomes. Hardened stone cannot be broken with regular tools; only diamond and netherite pickaxes break it. Hardened blocks can be identified by clicking them with a pickaxe or a stick.
TNT becomes the way to open hardened rock. Detonating it fractures the surrounding stone within a configurable radius, leaving the fractured stone around the blast site normal to break. The radius is set with a command, so server owners can tune how far a blast reaches. The mod also adds a simple gunpowder recipe: sugar, redstone, coal and charcoal can be combined anywhere on the crafting grid. Hard Rocks runs on client and server, so the server and every player need it, and it requires Fabric API.
Key features
Hardened stone
Deep solid rock becomes hardened stone that only diamond and netherite pickaxes can break.
Fracturing with TNT
A TNT blast softens stone inside a configured radius, so the area around it can be broken with ordinary tools.
Configurable blast radius
Server owners set the radius of the fracturing blast with a command.
Gunpowder from any grid
Sugar, redstone, coal and charcoal combine into gunpowder anywhere on the crafting grid.

Use cases
Realistic survival mining
Players who want excavation to feel slower and more deliberate can rely on pickaxe tiers and TNT to reach dense rock.
Vanilla-plus modpacks
The mod fits alongside realism-focused packs that keep the vanilla core design.
Who it’s for: Players and server owners who want mining to be harder and more deliberate in Minecraft 1.21.1, and who are comfortable running a Fabric client and server together.
How it compares
Stone Drop is server-side only, released under the MIT License and published for 1.21 – 1.21.11, so players need nothing installed. Excavation Shovel is optional on either side, all rights reserved, and covers 1.21.8 – 1.21.11. Netherite TNT Drops is also server-side only and MIT licensed, but it changes what TNT drops rather than how stone is mined.

What the author says
Hard Rocks is a simple mod to make mining more challenging and realistic while staying faithful to Minecraft's core design. Stone/Deepslate that is exposed in caves, cliffs and mountains can be mined normally. But the deeper you dig into solid rock, the harder it becomes.
