FAQ

How do I open the leveling screen?

Use the configured keybind in Minecraft's controls menu. The default key may vary between packs.

Do I need the original Just Leveling mod?

No. Use this fork by itself.

Can I use this in a modpack?

Yes.

How do I add or change item restrictions?

Edit the generated config files in .minecraft/config/JLFork/, especially justleveling-fork.lockItems.json5. The wiki has examples and accepted aptitude names.

A compatibility issue or restriction is missing. What should I do?

Open an issue with the item/block/entity ID and the mod it comes from so support can be added or documented.
