Prosperity — Loot Overhaul

Every chest, yours to discover.

Also on Modrinth and GitHub Releases. Visit the website for the full feature list, config reference, and command guide.

Prosperity is an instanced loot overhaul for Minecraft 1.21.1 (Fabric). It gives every player their own loot from naturally generated containers — no more racing to the good chests on a shared server — and rewards exploration with distance-scaled loot quality. It works by attaching per-player loot to vanilla containers via persistent Fabric data attachments and intercepting interactions through events; it never registers custom blocks or replaces block entities.

A focused overhaul. A drop-in replacement for Lootr with extra reach. Zero external dependencies beyond Fabric API.

At a glance

• Minecraft 1.21.1, Fabric loader (0.16.10+), Fabric API required.
• Install on the server and every client.
• Tunable through config/prosperity.json — hot-reload with /prosperity reload.
• MIT licensed.

Features

Instanced Loot

Every player gets their own independent loot from each naturally generated container, rolled the first time they open it and stored per UUID. Hoppers and comparators see an empty vanilla container — instanced loot lives outside the vanilla inventory, preventing extraction and duplication exploits.

Unlooted Indicators

A gold sparkle hovers above containers you haven't opened yet, and disappears once you've looted them. No more backtracking through strongholds, mansions, and mineshafts to find what you missed. The indicator is a world-space overlay, not a HUD element.

Distance Scaling

Loot quality scales with absolute distance from world origin across five tiers:

Stack quantities scale by the multiplier (capped at 64); quality adds luck to loot generation. The End is always treated as Depths tier. Structure overrides can fix, raise, or cap the tier a given structure uses.

Loot Modifier API & Injection

A stable, Fabric-style LootModifierCallback event lets other mods adjust loot generation after distance scaling. A datapack-driven injection system adds custom items to vanilla loot tables gated by minimum distance tier — and Prosperity ships built-in injections so distance scaling feels meaningful out of the box.

Commands

Player commands: /prosperity info. Operator commands cover per-player and per-container reset, viewing other players' tiers, and reload. Full reference: prosperity.rfizzle.com/commands.html

Optional integrations

Prosperity detects and integrates with these mods when present. None are bundled — install whichever you already use.

• Jade / WTHIT — container loot-status, distance-tier, structure-override, and refresh-timer tooltips
• EMI / REI / JEI — loot injection recipes

For mod developers: a stable Loot Modifier API (com.rfizzle.prosperity.api) — see the developer docs.

Requirements

• Minecraft 1.21.1
• Fabric Loader 0.16.10+
