Trial Catacombs
by saltlamp_
Trial Catacombs is a NeoForge dungeon mod for 1.21.1 in which players explore a fixed-structure tomb full of combat rooms, skeleton guards and a boss.
What it does
The mod generates a fixed-structure dungeon buried underground. Its main path has room types such as combat, supply and trap rooms, and the path always ends in a boss room. A branching route leads to three-altar trial rooms, where the door control system decides how players move between chambers. Three skeleton guards with distinct roles defend the dungeon, and the boss fight has several phases.
Completing the optional challenge is needed to reach the hidden trial chambers, where a skeleton king's commands grant access to unique weapons. Four skeleton entity models with their animations come with the mod. Configuration options cover most of the dungeon's settings. The mod requires Geckolib, which must be installed alongside it. Files are published for NeoForge 1.21.1 only, and the latest is version 1.1.0, released 2026-09-17. The server and every player need the mod installed. The license is custom and the mod is not open source, though its source code is public.
