Early cave loop
For Blackstone, drop below Ruined Official Road’s hollow corridor and inspect the lower cave chest near Hanging Cage Path; poison haze makes the latter unsafe to linger in. Rescue Zhang using the upper cave mechanism, then meet him at Thieves’ Camp before handing in treasures.
Tunnel treasure and Amber
Get the tunnel crank near the butcher beyond Desperado Trap. Open the passage at the fork, descend and cross the bridge: the left-wall green chest past the butcher holds the snuffbox. At the lower ladder turn left through the small door for an Amber chest. Speak to injured bandits while here.
Lodge and dungeon loop
At Cliffside Lodge, climb to the upper floor for the cellar switch. Downstairs, check the green-lit right chest for Amber and the platform-route chest for Blackstone. Collect both the secret-room switch and dungeon key as you traverse the platforms. Open Thieves’ Camp’s deep door: the right alcove contains Ancient Crossbow. Clear the bottom enemies for the cell key, open the upper Amber cell, then inspect the lower corridor’s left glow for another Amber.
Final camp checks
From the camp’s left cave, open the alcove chest for Bloodstained Seal; on the route out, inspect the house across the stairs for Blackstone. Choose the weeping mirror in the mirror puzzle. Complete healer and letter tasks before Bai Chilian; the six Inanis flowers and Banyan trial are separate detours linked below.
