Loot Table Modifier

Why?

Vanilla datapacks can only replace existing loot tables, which is not good for being compatible with other datapacks that also try to replace the same table.
This mod fixes that by implementing a system of loot modifiers, which do just that, modify loot (tables)!

Unlike some other mods (ahem KubeJS) which work by running code at runtime to intercept and change drops, Loot Table Modifier modifies the loot tables as they're loaded from datapacks.
This means that the mod will only hurt performance during data loading, but has no performance impact during gameplay!¹

¹ Except when you make zombies drop a bajillion stacks of diamonds or something crazy like that, but that's really not the mod's fault 😅

Usage

Players

This mod does nothing when installed on its own. There needs to be some sort of datapack present that uses loot modifiers.
If you are using some mod or datapack which depends on Loot Table Modifier, just download the latest version for the Minecraft version you use from the versions page and add it to your mods folder.
