Build a Dungeon Labyrinth Guide: Update 6 Three-Floor Maze

What the Build a Dungeon Labyrinth Is

[GUILDS] Build a Dungeon is a Roblox simulation and tycoon game by Exploration Guild, still in beta, with six-player servers and no voice chat or camera support. The base game is defensive: heroes enter through a one-way entrance, follow the corridors you lay down, and try to destroy your dungeon crystal while your monster units and traps wear them down.

The Labyrinth is the exploration mode Update 6 added on top of that loop. The developer describes it as a randomly generated maze containing monsters and treasure chests, with three floors in a single run. You can explore alone or with friends, group rewards are shared, and difficulty scales between runs so harder attempts pay out more.

How a Labyrinth Run Works

1. Choose Solo or Co-op: Start alone or bring friends, since group rewards are shared.
2. Descend Three Floors: Every run is regenerated, so no two descents share a layout.
3. Fight and Open Chests: Clear the monsters in the maze and open the treasure chests you find.
4. Step Up the Difficulty: Take harder runs as your units and upgrades improve, because rewards scale with the difficulty you pick.
5. Bank the Drops: Keep the payout and work toward the four Labyrinth-exclusive units.

Because each descent is generated fresh, there is no fixed route to memorise, and the units, mutations and upgrades you bring decide how far a hard run can go.

Shrine Tiles and the Rest of Update 6

Update 6 also added four Shrine Tiles that buff the units placed around them, and nothing can be placed on top of a Shrine Tile, so the tiles you leave empty around a shrine are what turn it into a buff zone. The same update added five new units and tiles, four Labyrinth-exclusive units, Divine pity and Mutation pity mechanics, advanced auto-roll filtering for repeated rolls, and an earlier unlock of the 2x Battle Speed skill-tree upgrade. Hero waves above 500 were strengthened, and a dropdown was added for returning to a previous checkpoint.

Warning

The developer has not published the exact pity thresholds or roll rates for Divine units or for mutations. Treat any specific percentage you see outside the game as unverified and confirm the current values on the in-game interface.

Update 7 moved the game into its [GUILDS] era: guilds are now in beta, and the update notes cover mutation changes, trap upgrades and auto rejoin.

Units and Mutations Behind a Labyrinth Run

Units defend your dungeon: some fight up close, some attack from a distance, and others heal or buff nearby units. The rarity ladder runs Common, Uncommon, Rare, Epic, Legendary, Mythic, Secret and Divine.

Close-Range Fighters

Common units such as Bone Ghoul, Goblin Scout and Skeleton Warrior sit at the bottom of the ladder, below the Legendary and Divine pulls that take far more rolls.

Ranged Attackers

Some units attack from a distance, and hero archers have been recorded hitting units through walls.

Support Units

Support-tagged units such as Grove Healer, listed as Support and Magic, heal or buff the units around them.

Official drop rates are not published, so the milestones below are what players observed in recorded runs rather than a developer-confirmed table.

Mutations raise health, damage, population and Dark Souls cost together.

Mutations do not change a unit's attack interval, range or ability percentages, and boss units get 50% more health and damage in a Boss Room.

Preparing Your Dungeon Before You Enter the Maze

Labyrinth runs draw on the same economy as your dungeon: Coins buy buildings, traps and parts, Dark Souls buy monster units, and Coin Booster and Soul Booster Potions temporarily multiply what you earn. Recorded runs show parts such as stone corridors, curved corridors, dead ends, crossroads, junctions, treasure rooms, graveyards, lava chambers, ballista towers, turrets, blacksmiths and Life Springs, plus traps including spike traps, poison traps, tar pits, bear traps, arrow traps, fire traps, falling rocks, oil and lava floors.

• Thief-class heroes disarm traps in a one-tile radius around themselves, so keep unit damage in the mix.
• Hero healers restore heroes, and ranged archers can shoot through walls.
• Spend booster potions during sessions where you are actively clearing waves, so the multiplier is not wasted.
• The official description states that monsters catch heroes offline, so progress continues between sessions.
• Recorded runs show a checkpoint at wave 10, and Update 6 added a dropdown for returning to a previous checkpoint.
