vaultloot
Added in-game command functionality to adjust the loot probability (item weight) and rarity distribution ratios for both the vault and the ominous vault.
⬇ Download on ModrinthVault Loot Console is a server-side Fabric mod that lets you adjust the loot probabilities for the Vault and Ominous Vault using simple in-game commands.
Features
- Item-level probability – Modify the weight of any item in the vault loot tables: make diamonds never appear, or make the Heavy Core almost guaranteed.
- Rarity tiers – The vault loot table has a two‑layer structure. You can adjust the top‑level selection weights for the
common/rare/uniquepools, and also drill down into each pool to fine‑tune individual items. - Instant effect – Changes take effect immediately via a data reload (
autoApply), and all modifications are persisted inconfig/vaultloot.json. - Easy to revert – Run
/vaultloot resetor delete the config file to restore vanilla behaviour.
