Mining deepslate has always felt inconsistent. Same tools, same enchants, slower mining speed for no meaningful gameplay reason.
Instamine fixes that by reducing the hardness of selected blocks to match the hardness of regular stone. This means with Efficiency V & Haste II, affected blocks become practically instamineable, just like stone.
Features
- Makes deepslate and endstone instamineable out of the box
- Fully customizable block list through the Mod Menu mod or the config file
- Configurable target hardness for those who have other things in mind
- Works server-side without requiring clients to install the mod
Dependencies
Latest Release
- Required: Cloth Config API
- Optional: Mod Menu
Configuration
The mod configuration includes the blocks list, the ore/log toggles, and the hardness value, all of which can easily be edited through Mod Menu or directly through config/instamine.json after its generation.
Default Changes
| Block | Vanilla Hardness | Instamine Hardness |
|---|---|---|
| Deepslate | 3.0 | 1.5 |
| Endstone | 3.0 | 1.5 |
| Cobblestone | 2.0 | 1.5 |
| Cobbled Deepslate | 3.5 | 1.5 |
| Ores (all variants) | 3.0 - 4.5 | 1.5 |
| Logs & Wood (all variants) | 2.0 | 1.5 |
1.5 is the vanilla hardness of stone and yes cobblestone is originally not instaminable.
Ores & Logs
Rather than typing keywords into the block list, ores and logs each get their own dedicated toggle in the config screen.
| Toggle | Spans | Default |
|---|---|---|
| Ores | All 20 vanilla ore variants (stone & deepslate) | On |
| Logs | All 42 vanilla log/stem, wood/hyphae, and stripped variants | Off |
Everything else, individual blocks like deepslate or end stone, still goes in the block list.
Servers
Instamine works server-side for all players, technically even without the mod installed on their client.
Installing it on both server and client is recommended however so the mining animation stays visually consistent and coherent.
