About this project

About
The Tricky Trial Update for Minecraft 1.21 introduced Trial Chambers. While these structures are intended to spawn in all Overworld biomes except the Deep Dark, some mod-added biomes lack support for them. This mod generates Trial Chambers in all biomes where Mineshafts generate, thereby reducing the number of mod-added biomes without Trial Chambers. They will not generate in biomes where Mineshafts do not generate, such as the Deep Dark or the Origin Series biome from Biomes O' Plenty.
Require MOD
Fabric requires the Fabric API only when loaded via Mod Loader.
