Frequently asked

Does Random Item Skyblock work on Minecraft 1.21.4?

Yes. 1.21.4 is the newest Minecraft version Random Item Skyblock declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does Random Item Skyblock support?

Everything the author has declared, from 1.14.4 up to 1.21.4. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Random Item Skyblock on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

Which loader does Random Item Skyblock need?

Fabric. A build for one loader will not load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Random Item Skyblock?

Java 21 or newer, because that is what the newest Minecraft release it supports requires. The requirement comes from the game rather than from the modpack itself.

What licence is Random Item Skyblock under?

LicenseRef-All-Rights-Reserved, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Random Item Skyblock?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the modpack and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Random Item Skyblock safely?

From the author's own page on Modrinth, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.
