Mod Icterine

Icterine, Advancements Optimization

Icterine is a server side optimization mod for Minecraft Java Edition that focuses on the advancement system, especially the resource intensive InventoryChangeTrigger. This trigger checks inventory updates against advancement criteria whenever players obtain, move, or modify items, which can become costly in large modpacks and datapack heavy servers.

Icterine reduces unnecessary checks by filtering changes such as emptied stacks, minor quantity updates, container opening events, and irrelevant item comparisons. Its injections are configurable, and the mod aims to preserve vanilla rewards while acknowledging that parity may differ in uncommon custom setups. On BoxToPlay, it can help make a busy Minecraft server more efficient without requiring clients to install it.
