About this Mod

Item Progression

This mod adds a leveling system, which prevents players from using certain items before they reach a specified level in the corresponding skills.
The list of available skills and requirements is fully configurable.
Additionally the mod makes spawners and fully grown crop blocks drop a specified range of xp; this can be configured or disabled in the same config file.

Frequently Asked Questions

Item Progression server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Item Progression compatible with fabric?

Item Progression officially supports fabric for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Item Progression – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Item Progression consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
