vaultloot

Vault 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 / unique pools, 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 in config/vaultloot.json.
• Easy to revert – Run /vaultloot reset or delete the config file to restore vanilla behaviour.

Loot Table Aliases

| Alias | Controls |
|——-|———-|
| normal / ominous | Top‑level selection weights for the common / rare / unique pools (rarity bias) |
| normal_common / ominous_common | Common pool (emeralds, arrows, wind charges, small amounts of diamonds, …) |
| normal_rare / ominous_rare | Rare pool (armour, weapons, enchanted books, diamond blocks, …) |
| normal_unique / ominous_unique | Unique pool (enchanted golden apples, smithing templates, tridents, Heavy Cores, …) |

Usage Examples

Make every ominous vault drop a Heavy Core guaranteed (set all other unique‑pool entries to weight 0, and zero out the other pools):

/vaultloot set ominous minecraft:chests/trial_chambers/reward_ominous_rare 0
/vaultloot set ominous minecraft:chests/trial_chambers/reward_ominous_common 0
/vaultloot set ominous_unique minecraft:enchanted_golden_apple 0
/vaultloot set ominous_unique minecraft:flow_armor_trim_smithing_template 0
/vaultloot set ominous_unique minecraft:flow_banner_pattern 0
/vaultloot set ominous_unique minecraft:music_disc_creator 0

Make diamonds no longer appear in the normal vault’s common pool:

/vaultloot set normal_common minecraft:diamond 0

Installation & Multiplayer

• Server: required (for single‑player, install on the client).
• Client: optional. Vanilla or unmodded clients can still join without issues by default.
