Legacy Utils
by dappls
Legacy Utils is a client-side Fabric mod that adds helper features for the Minigame category, covering puzzle solvers and an info menu for Hypixel-style dungeon rooms.
What it does
Players who run the Legacy Utils client get solver helpers for several puzzle rooms, along with an info menu that lists the 101 Halls door. The features support the parts of the game that the mod's author describes as legacy content. Only the client needs the mod, so a server does not have to install it and players can join without it.
Builds cover 1.21.2 – 1.21.11 and are published for Fabric only, with 1.1.0 for 1.21.11 as the latest file, released 2026-07-27. The code is licensed under the MIT License and is open source, and public source code is available.
Key features
Puzzle solvers
Solvers for the LightsOut puzzle in several variations, with a GUI menu for rendering their results on screen.
Dungeon and water maze aids
Trails and markers for the Water Maze, the pickaxe boss room, conduits, the dungeon lamps and wind charge.
Spirit trails
Trail overlays for the M2.5 and M3 spirit layouts are included in the same client.
