Loot Injector

Loot Injector injects loot into the loot tables of vanilla and modded structures, including dungeons, bastions, strongholds, villages and shipwrecks, as well as mob drops and fishing loot. Each injection rule sets the items it adds, and every item carries its own independent drop chance, from 0.01% up to 100% per chest opening. Stack counts take minimum and maximum values that accept decimals, so an averaged count can be set with fractional bounds. Items can carry full NBT data through SNBT tags, which makes it possible to add enchanted or otherwise customized variants of items from other mods.

The mod also defines Custom Loot Chests: named chest configurations with pools of fixed and weighted random items. A player receives such a chest through a command, and its items are rolled in advance when it is given. Configuration is available in a three-panel in-game editor covering loot pools, entries with weight bars and count ranges, custom chests, and a raw JSON tab with live syntax coloring. Editing the files directly is also possible. The commands require operator level 2. The mod is licensed under the MIT License, with files for 1.20.1 – 1.20.4 published for Forge only, and it needs both the server and each player to run it.
