Build a Dungeon Guilds Update: Guilds Beta, Mutations, Traps

What the Build a Dungeon Guilds Update Is

The Roblox listing currently reads [GUILDS] Build a Dungeon, and the bracketed tag follows the live update: the same game page previously carried the [LABYRINTH] tag. The guilds update is the change set behind that tag, and its confirmed scope is narrow — guilds enter beta, and the notes shipped with it cover mutation changes, trap upgrades, and auto rejoin. The experience is still in beta and is updated regularly.

Guilds in Beta

Membership limits, creation costs, and rewards are not published in the sources reviewed here, so confirm them in the in-game guild interface.

Mutation Changes

Mutations alter health, damage, Dark Souls cost, and population. Recheck the in-game index before committing currency.

Trap Upgrades

Traps are bought with Coins, so an upgrade pass changes what your defense budget buys. Check current costs in the build menu.

Update 7 Changes: Guilds, Mutations, Traps, and Auto Rejoin

Auto rejoin matters because the official description states that monsters catch heroes offline, so part of a session's value is collected while you are away. Its exact behavior and any cooldown are not published, so treat the in-game result as the source of truth.

What Update 6 Added

The guilds update builds on Update 6, which is where most of the currently visible systems came from.

Mutations and Roll Milestones

Those are the in-game index values recorded by the community reference. Boss units also receive 50% more health and damage in a Boss Room. Unit rarity runs Common, Uncommon, Rare, Epic, Legendary, Mythic, Secret, and Divine, and community gameplay footage shows the roll milestones displayed in game at 80 rolls for a Legendary, 160 for a Mythic, 300 for a Secret, and 2,000 for a Divine.

Warning

Official drop rates and pity thresholds are not published. Where another page quotes exact percentages or guaranteed pull counts, verify them in the in-game interface instead of planning your Dark Souls spending around them.

Traps, Rooms, and Units in the Updated Defense

Heroes enter through a one-way entrance, walk the corridors you lay, and try to reach your dungeon crystal. Buildings and parts seen in gameplay include the stone corridor, wooden floor, curved wall, curved corridor, dead end, crossroads, junction, armory, treasure room, dragon nest, graveyard, lava chamber, frost stone wall, wooden barricade, ballista tower, turret, blacksmith, Life Spring, and Shrine Tiles.

Traps are what an upgrade pass touches directly: spike traps, poison traps, tar pits, bear traps, wall-mounted arrow traps, fire traps, falling rocks, oil, and lava floors. Tar pits slow heroes down, oil keeps a hero burning for three tiles after it is stepped in, and lava floors increase fire damage.

• A treasure room always draws heroes toward it, which makes it a reliable place to build around.
• A potion shop lets heroes buy potions and is one of the main sources of income.
• Thieves disarm traps within a one-tile radius, healers heal other heroes, and archers can attack through walls while your units cannot.

Skill-tree nodes follow the same resource logic: gold rush, soul harvest, unit damage, population, trap mastery, battlecry, and battle speed. If a run fails, you restart from your most recent checkpoint; gameplay footage shows a checkpoint at wave 10.

Tip

Because a thief disarms traps within one tile, spread upgraded traps so a single disarm cannot clear a whole corridor.
