Beneath the frozen earth of our Whiteout Survival world, a realm of shifting mists and quiet echoes beckons—the Labyrinth. Since its unveiling in those early days when my furnace first roared at level 19, this underground maze has been both a crucible and a treasure trove. It is a place where forgotten might slumbers, and each step into the gloom exacts a toll measured in wit and resilience. As a veteran explorer who has danced with its RNG and charted its weekly rhythms, I now walk you through this cavernous puzzle, its gleaming rewards, and the subtle art of turning confusion into triumph.

The Threshold of Shadows

The Labyrinth awakens when your Furnace reaches Level 19, accessible through the Command Center—a portal to a world where daylight’s rules are mere memories. In fresh servers, the mists part around the second week, often aligning with the rise of the second Hall of Chiefs, as if fate itself orchestrates our first descent. I remember my own initiation: day 18, a Monday, the notification flickering like a candle in a blizzard.

Not all chambers reveal themselves immediately. Some zones slumber until you’ve tamed generation one Pets (~54 days old), others until Chief Gear and Chief Charm whisper their secrets at Furnace Levels 22 and 25. The six domains—Land of the Brave, Cave of Monsters, Glowstone Mine, Earthlab, Dark Forge, and the ultimate Gaia Heart—are locked behind the gates of your progress, urging you to grow in power before the full splendor unfolds.

The Weekly Cycle of Mist and Majesty

Each day, the Labyrinth dons a new veil. The schedule is a cosmic dance: Land of the Brave dominates Monday and Tuesday, a proving ground for heroes and their gleaming gear. Cave of Monsters and Glowstone Mine share Wednesday and Thursday, where pets and charms hold sway. Earthlab and Dark Forge command Friday and Saturday, rewarding those who have toiled in research and forged Chief Gear. Then comes Sunday—a sacred day for Gaia Heart, where all your expedition might converges into a maelstrom of heroes, pets, charms, gear, tech, skins, Daybreak Island, and even VIP status. No minister position, no facility advantage; just raw, cumulative power.

The Soul of a Zone: Expedition Stats

Unlike the sunlit skirmishes of Exploration, the Labyrinth draws exclusively from Expedition stats and skills—the same force that slays Beasts and dismantles Mercenaries. Here, your arena pomp means nothing; it is a PvE ballet where each arena demands a different costume.

  • Land of the Brave: Heroes, Hero Gear, Hero Exclusive Gear

  • Cave of Monsters: Pets and their skills (automatically active, sparing precious cooldowns)

  • Glowstone Mine: Chief Charm

  • Earthlab: Research Center and War Academy Tech

  • Dark Forge: Chief Gear

  • Gaia Heart: The grand symphony—Heroes, Gear, Pets, Charm, Gear, Tech, Skins, Daybreak Island, and VIP Level. Yet even here, some whispers fail: Minister bonuses and Facility buffs stay silent.

Troops and the Art of RNG

In all zones but Gaia Heart, the Labyrinth Explorers lend us level 10 soldiers—equalizing raw might so that tactical cunning takes center stage. Only in Gaia Heart may our Fire Crystal or Helios legions march forth, with the game supplementing any shortfall. The default enemy formation stands at 33/33/33 Infantry/Lancer/Marksman, but the 10th stage twists into a 53/27/20 serpent, demanding a tailored answer.

My own experiments whisper of a 50/20/30 ratio as a sturdy foundation, yet in multi-wave duels (2v2, 3v3) where turn-order RNG reigns, I’ve found 52/13/35 or 60/12/28 more merciful—preserving damage dealers through repeated rounds. In 1v1 zones without hero theatrics, I’ve often thinned my lancers down to 50/10/40 or even 60/5/35, leaning on the fickle Ambusher (20% chance to strike rear marksmen) and Volley (10% chance to strike twice) to swing the tide.

I recall a stubborn stage where my 54/6/40 faced the AI’s 33/33/33: lost twice despite heroic Ambusher procs, then won on the third when my lancers’ fangs finally found their mark. RNG is a mercurial ally—one you cannot solely rely on. When raw stats fall short, no number of rerolls will breach the wall; patience and growth become your truest guides.

Five Chances Each Day

Each zone grants five challenge attempts daily, refreshing at 00:00 UTC—precious oracles that let you retaste a defeat with a new formation, a swapped hero, or simply by hoping the dice roll kinder. Perhaps you’ll spend hard-won upgrade materials to bolster that week’s expedition stats, or you’ll brute-force with three identical attempts until the RNG gods smile. I’ve done both; the Labyrinth rewards the persistent.

The Harvest: Rewards and Raid Rhythms

Clearing a zone for the first time bestows a rain of Glowstones and Labyrinth Treasure chests—especially at every 5th and 10th stage. Once the mists reset weekly, Raid Rewards flow based on your highest previous clear, like a tax on your earned glory. The math is simple: multiply total cleared stages across all zones by 10 to know your weekly Glowstone income. Milestone rewards, fueled by Labyrinth Cores, unlock further treasures and even two Daybreak Island decorations.

The Hero’s Sanctum grants up to +2.5% troop defense at level 5 (15 copies), while the Luminary Citadel climbs to +10% troop attack at level 10 (58 copies). These ornaments drop from Labyrinth Treasure and Splendid Labyrinth Treasure, adding enduring power to your island.

Opening hundreds of these chests yields a cascade of hero shards, upgrade components, Mithril, and more—a true alchemist’s delight.

The Glowstone Ledger: Shop Wisdom

In the Labyrinth Shop, Glowstone turns into lasting strength. My counsel, honed by years of icy winds, is this: prioritize Mythic General Shards early, for their early-game scarcity pinches like a frozen gear. Next, the Lucky Hero Gear Chest and 100 Enhancement XP Component will shape your heroes into legends. Once your weekly income allows, stockpile Mithril long before Legendary gear appears—frontloaded foresight pays dividends. Then come Charm Designs (far rarer than Guides) and eventually Fire Crystal Shards when the War Academy opens its doors. Resist the siren call of speedups unless a desperate Furnace 30 sprint justifies the sacrifice; the Labyrinth’s true wealth lies in compound growth.

Into the Mist, Ever Deeper

As the seasons turn in 2026, the Labyrinth remains a weekly pilgrimage—a place where preparation meets chance, and every clever adjustment inches us closer to that next milestone. The underground mists may shroud our past progress, but they also promise a fresh bounty. Equip your heroes, refine your ratios, and let the Glowstone’s hum guide your steps. For in the depths of the Labyrinth, the cold never truly leaves, but neither does the warmth of hard-won victory.
