Build a Dungeon Labyrinth Rewards: Chests, Units & Currency

What the Build a Dungeon Labyrinth Adds

Update 6 introduced a randomly generated Labyrinth that spans three floors per run, filled with monsters and treasure chests. The developer confirms rewards are shared when you explore with friends, so solo and co-op play are both supported. It sits alongside the defense you already run: heroes enter through a one-way entrance and follow your corridors toward the crystal, where your monster units catch them.

Treasure Chests

Every Labyrinth run contains treasure chests. The developer has not published what each chest can hold, so open them in game rather than trusting a third-party loot list.

Four Labyrinth-Exclusive Units

Update 6 added four units labeled Labyrinth-exclusive, giving collectors a reason to keep running the mode after the currency rewards stop mattering.

How Difficulty Changes Your Labyrinth Payout

If you are optimizing build a dungeon labyrinth rewards, the difficulty you pick before a run is the biggest lever you control: the payout is tied to difficulty, not to how long you spend inside. Higher difficulties are meant to be attempted as your monster units improve, and no official power levels or per-difficulty reward tables exist, so the in-game Labyrinth screen is authoritative.

1. Read the Labyrinth screen first: check the difficulty options and reward description before you commit to a run.
2. Pick the hardest difficulty your units can finish: a completed harder run is worth more than a failed easier one.
3. Bring a friend when the option is available: co-op rewards are shared, so a group collects from the same clear.
4. Reinvest the payout: Coins buy buildings, traps, and dungeon parts, while Dark Souls are spent rolling for monster units.

Labyrinth-Exclusive Units and Roll Milestones

Update 6 also added five new units and tiles, four Shrine Tiles that buff the units placed around them, and four Labyrinth-exclusive units. The rarity ladder runs Common, Uncommon, Rare, Epic, Legendary, Mythic, Secret, and Divine, and recorded gameplay shows these roll milestones for the top of it.

Those figures come from player recordings, not an official rate table. Update 6 also added Divine pity and Mutation pity systems, and the developer has not published the roll counts, percentages, or thresholds they use, so treat the in-game interface and the in-game Index as the source of truth.

Tip

The community update log lists Update 7 as moving Guilds into beta with mutation changes, trap upgrades, and auto rejoin. Re-read the in-game update notes after a patch instead of relying on an older guide, this one included.

Booster Potions and Codes That Raise Your Payout

Coin Booster and Soul Booster Potions temporarily improve your rewards, which makes them worth saving for a run you expect to finish. The LABYRINTH code is the reward source tied most directly to this mode, granting 3 Soul Booster Potions, 10,000 Coins, and 1,000 Dark Souls.

Redeem codes from the Settings button in the top-left corner of the screen, then press Redeem after typing the code in. Codes are case-sensitive, and trackers disagree on the exact amounts attached to a few of them, so the redemption message in game is the final word. New codes are announced through the official Discord and the Exploration Guild developer community.

Where the Rest of Your Rewards Come From

The Labyrinth is not the only payout, and its currency spends like everything else. Defeating hero waves pays Coins and Dark Souls, and the official description confirms monsters keep catching heroes while you are offline.

Mistakes That Cut Your Rewards Short

Warning

A pure trap corridor can be dismantled mid-wave. The thief hero class disarms traps within a one-tile radius as it moves, healer heroes keep the rest of the wave alive, and archer heroes can attack over walls even though your own monster units cannot attack through a wall.

Failing a level is not permanent: recorded gameplay shows a checkpoint at wave 10, and a failed level restarts from the most recent checkpoint, so progress is measured in waves rather than in one attempt.

• Confirm the current difficulty and reward text on the in-game Labyrinth screen before starting a run.
• Save Booster Potions for a difficulty you are confident you can finish.
• Mix traps with monster units so a single thief cannot strip your whole defense.
• Place units with clear sight lines, since units cannot attack through walls.
• Check the in-game Index after a run to track which Labyrinth-exclusive units you still need.
