FTB StoneBlock 3

What sets it apart

StoneBlock 3 flips the skyblock idea. Instead of an island in empty air, the player starts in a small pocket inside a world that is solid stone and has to dig outward. FTB’s own page describes world generation arranged in rings around the starting base, plus custom structures, custom bosses and scripted events.

It is the third pack in the StoneBlock line and runs on Minecraft 1.18.2 with Forge. Progress is guided by a quest book, but the FTB page frames it as a sandbox with goals rather than a strict gated pack.

FTB’s pages do not publish a mod list in their description. A mod list kept by the MineYourMind server network for its StoneBlock 3 server includes Create, Mekanism, Applied Energistics 2, Refined Storage, Thermal Expansion, Botania, Ars Nouveau and Blood Magic, so both tech and magic routes are covered.

Who it suits

It suits players who like the “start with nothing” loop of skyblock but want mining and cave building instead of bridges over the void. The mix of tech and magic mods gives returning players plenty of automation goals.

Players who want open-world exploration with normal terrain will not find it here. The whole point is the enclosed stone world.

Before you install

FTB lists a minimum of 4 GB of RAM and recommends 6 GB, with Java 17 required.

The pack is published by FTB and distributed through the FTB App, with a listing on CurseForge as well. The FTB page lists 1.11.6 as the latest version and June 11, 2026 as the last update, though it also says “4 years ago”, so its dates conflict. The CurseForge page shows 1.11.5, dated May 30, 2025.

The total number of mods is not stated on either official page.

Playing with friends

Official server files exist. The FTB page points to its Versions tab and to the central Server Files browser on the FTB site.

According to the FTB Docs guide, the server download is a small installer program rather than a zip. It fetches the pack files and a matching Java build, and the guide warns not to rename the file because the installer reads the pack ID from its name. After it finishes, the server is started with the included run script (run.bat on Windows, run.sh on Mac and Linux).

The same guide says most FTB packs want at least 4 to 6 GB for a server and directs readers to each pack’s Requirements section. A separate player-count recommendation for StoneBlock 3 is not documented.
