The Moon Crypt's biggest secrets are the three hidden Lunar Mask Fragments required to challenge the area boss, a secret crafting station called the Blood-Weaver's Loom, and an optional boss, the Echo of the Star-Eater. This guide maps out every puzzle, hidden item, and enemy strategy needed to conquer this late-game optional dungeon in goblinAmerica.
While the main path is straightforward, the true rewards are tucked away behind illusory walls and cryptic puzzles. Mastering this area grants access to one of the best weapons in the game and a powerful accessory that can define an endgame build.
How Do You Get Into the Moon Crypt?
Access to the Moon Crypt is locked until you progress far enough in the main story. You cannot enter until you acquire the Star-Chart Key, a quest item awarded for completing the "Sunken Observatory" dungeon and defeating its boss, Astrolager Vex. Once you have the key, the entrance can be found in the northernmost region of the Whispering Peaks.
Look for a large, crescent-shaped rock formation. The entrance is not a cave but a monolithic stone door covered in faded constellations. Use the Star-Chart Key on the pedestal in front of the door to open the way. Be prepared: the enemies inside are high-level spectral types, primarily weak to Void and Arcane damage.
The Three Lunar Mask Fragments: Step-by-Step Locations
The primary objective within the Moon Crypt is to collect three fragments of a key—the Lunar Mask. These pieces are scattered across three distinct wings of the crypt, each locked behind a unique environmental puzzle. Once assembled, the mask opens the final door to the area's main boss, the Sentinel of the Silent Moon.

Fragment of the Waxing Moon (Gravity Puzzle Room)
This fragment is located in the crypt's eastern wing. You'll enter a large chamber with a seemingly impossible gap. The room is filled with floating platforms that materialize and dematerialize based on which gravity crystal you strike.
- Upon entering, strike the green crystal on your right. This activates the first set of platforms leading to a central island.
- On the central island, ignore the blue crystal. Instead, look for a hidden red crystal on the underside of the island. You'll need to use a projectile or a weapon with a downward slam attack to hit it.
- Hitting the red crystal inverts the room's gravity, pulling you to the ceiling. Navigate the ceiling platforms to the far side of the room.
- Strike the final green crystal on the far wall to restore normal gravity, dropping you onto the ledge with the chest containing the Fragment of the Waxing Moon.
The key is hitting the hidden red crystal. Most players get stuck trying to find a sequence using only the visible green and blue crystals.
Fragment of the Waning Moon (Light-Beam Brazier Puzzle)
The western wing houses a large, dark chamber with a single beam of light projecting from the ceiling. Your goal is to use a series of four rotatable statues with mirrored shields to direct this beam into three specific braziers in the correct order.
The solution is hinted at by a carving on the wall showing the lunar cycle. You must light the braziers in the order of the waning moon: Gibbous, Half, then Crescent.
- Gibbous Brazier: Rotate the first and second statues to bounce the light toward the large brazier carved with a gibbous moon.
- Half-Moon Brazier: Rotate the third statue to redirect the beam toward the half-moon brazier in the corner.
- Crescent Brazier: Finally, rotate the second and fourth statues to split and aim the beam at the final crescent-shaped brazier near the entrance.
Once all three are lit in this specific order, the alcove holding the Fragment of the Waning Moon will open.
Fragment of the Full Moon (Behind the Star-Eater)
This is the simplest fragment to acquire but the hardest to earn. It is not found via a puzzle but is a guaranteed drop from the Moon Crypt's secret optional boss, the Echo of the Star-Eater. Finding and defeating this boss is one of the dungeon's core secrets.
How to Find and Defeat the Echo of the Star-Eater
The Echo of the Star-Eater is a powerful spectral beast hidden deep within the crypt. Defeating it is essential for finding all the Moon Crypt secrets, as it drops the final mask piece and a unique accessory.
Finding the Hidden Arena
In the central hub of the crypt, there's a large, circular room with a sealed stone door. Opposite this door is a seemingly blank wall. However, if you look closely, you can see a faint constellation pattern etched into the stone that isn't present on any other wall.
To break the illusion, you must strike this wall with a weapon infused with the Solar Flare ability, which is learned from the "Blade of the Dawn" sword. Any other attack will have no effect. A direct hit will shatter the wall, revealing a shimmering portal to the boss arena, the Starlit Chasm.

Boss Strategy: The Echo of the Star-Eater
This boss is fast, aggressive, and hits hard. It has two distinct phases.
- Phase 1 (100%-50% Health): The Echo attacks with a relentless three-hit combo using its spectral claws. It will also periodically leap into the air and slam down, creating a shockwave. The key is to dodge through its claw attacks, not away from them, leaving it open for a few hits from behind.
- Phase 2 (Below 50% Health): The Echo becomes more dangerous. It begins summoning meteors that track your position, indicated by glowing sigils on the ground. It also introduces its most powerful attack: Lunar Tide. During this move, it will stand still and begin drawing in energy, exposing its Celestial Core. This is your primary damage window. Hit the core with Void damage for massive bonus damage. Failure to do enough damage will result in a room-wide explosion.
Upon defeat, the Echo of the Star-Eater drops the Fragment of the Full Moon and the Starlight Signet. This ring is a fantastic reward, increasing all Void damage by 15% and providing a slight resistance to spectral attacks.
Unlocking the Blood-Weaver's Loom & Founder's Safe
Beyond the main quest of the mask fragments, the crypt holds two major secrets: a hidden crafting station and a locked safe containing valuable lore and materials.
The Secret of the Blood-Weaver's Loom
In the same room as the light-beam puzzle, look for a waterfall of what appears to be starlight cascading down one wall. This is another illusory wall; simply walk through it. Inside, you'll find a hidden chamber containing the Blood-Weaver's Loom.
This unique crafting station allows you to weave the Gossamer Thread—a rare material dropped by the silvery Phase Spiders found throughout the crypt—into the Moonsilver Scythe. This endgame-tier weapon has high base damage, scales with your Arcane stat, and has a built-in life-leech effect, making it one of the best survival weapons in goblinAmerica.
Cracking the First Founder's Safe
In the antechamber right after the crypt's entrance, a large tapestry of the lunar cycle hangs on the wall. Burn it or cut it down to reveal a small vault door with a combination dial marked with lunar phases instead of numbers.
The clue to the combination is found etched onto the floor in the Gravity Puzzle Room: "First the new, then the half, last the full."
The combination corresponds to the order on the dial:
- Turn the dial to the New Moon symbol (a black circle).
- Turn it to the Half Moon symbol.
- Finally, turn it to the Full Moon symbol.

The safe will click open, rewarding you with the Founder's Journal, a lore item that sheds light on the crypt's origins, and a Celestial Core, a rare material used for max-level weapon upgrades.
Frequently Asked Questions about the Moon Crypt
What level should I be for the Moon Crypt? The enemies in the Moon Crypt are around level 40-45. It's recommended to tackle this area after you've completed the main story quests in the Sunken Observatory and Whispering Peaks, typically around level 42 or higher for a comfortable experience.
Is the Moon Crypt required to beat the game? No, the Moon Crypt is a completely optional area. You can finish the main storyline of goblinAmerica without ever setting foot inside. However, the rewards, particularly the Moonsilver Scythe and Starlight Signet, are powerful enough to make the final boss encounters significantly easier.
What's the fastest way to farm Gossamer Thread? The best farming spot for Gossamer Thread is the long hallway just before the Gravity Puzzle Room. Several Phase Spiders spawn here. You can run through, defeat them, then exit to the main hub and re-enter to force them to respawn. Using a weapon with a wide-arc attack can clear them out quickly.
The Final Verdict
The Moon Crypt is one of goblinAmerica's best-designed optional areas. It perfectly balances challenging combat with clever, rewarding environmental puzzles. While its main boss, the Sentinel, is a decent challenge, the true highlights are the secrets hidden off the beaten path. From the superb Moonsilver Scythe to the game-changing Starlight Signet dropped by the Echo of the Star-Eater, the treasures within are more than worth the effort it takes to uncover them.
