Deep in the volcanic region of Atocpan, Genshin Impact hides one of its most intriguing secrets—the Secret Source Dragon Idol. What appears to be a broken statue actually triggers a multi-stage puzzle leading to the “A Lonely Sentinel” achievement, along with three valuable chests.
This guide breaks down every step, from locating the dragon idol to escaping the lava-filled caverns with your rewards. Whether you’re an achievement hunter or just love Genshin’s environmental puzzles, this hidden gem is worth your time.
Locating the Dragon Idol
Your journey begins east of the “Collective of Plenty” in Atocpan. Near a dirt path teleport waypoint, you’ll spot a pool of lava with the dormant Secret Source Dragon Idol lying in it. A group of Hilichurls guards a Remarkable Chest nearby—clear them out, then shoot the explosive barrel beside the idol.
Key Tip: The barrel blast awakens the dragon, causing it to shatter a rock wall and reveal the entrance to an underground cave. Don’t miss this interaction!
Navigating the Lava Cave
Follow the dragon into the cave until you reach a new teleport waypoint. Here’s where things get tricky: the path ahead is blocked by lava, but the dragon will return to help. Hop onto its back, and it’ll ferry you to a safe ledge with a Common Chest.
After claiming it, the dragon reappears farther away, this time with an Exquisite Chest. To reach it:
- Head south and climb the slope to a higher platform.
- Jump onto the dragon’s back again to grab the chest, then leap to safety before it retreats.
Solving the Rock-Smashing Puzzle
On its third return, the dragon stops near a mechanism atop a statue head. Activate it to solidify the lava into breakable rocks. Now, use the nearby Tatankasaurus transformation (a geo-armored beast) to charge-attack the rocks, clearing a path downward.
Pro Tip: Smash every rock cluster—you’ll eventually reveal a hidden serpent statue and unblock a new tunnel. The dragon will wait at a barrier sealed by a golden emblem.
Freeing the Prisoned Servant & Claiming Rewards
Interact with the golden seal to dispel the barrier, freeing the trapped Secret Source Servant. Your reward? A Luxurious Chest and a note with lore. After reading it, ride the dragon one last time to an upper chamber, where the “A Lonely Sentinel” achievement unlocks.
Finally, a wind current spawns—use it to soar out of the cave and back to the open world.
