With update 1.6, Honkai: Star Rail introduces a new location at Hertha Station known as the Isolated Zone. Access is granted only after completing the quest The Crown of Mortal and Divine. When Ruan Mei’s task begins and the elevator is boarded, the Pathfinder finds themselves inside a fresh area to explore.
Secrets, riddles and puzzles in Honkai: Star Rail
Within this level, players can uncover 11 regular chests and 2 valuable chests. These rewards come from defeating tougher foes and solving intricate puzzles. This guide details the exact locations of all of them.
Note: Opening all areas within the Isolated Zone requires full completion of the Mastery mission Crown of Mortal and Divine.
First chest
Teleport to the third floor of the Isolated Zone, then ascend the small stairs opposite the spatial anchor.
Turn left and proceed through the narrow corridor. A regular chest rests behind the computer screen on the floor.
Second chest
From the previous teleport, turn left. Pass the round bridge and head toward a long corridor sealed by a wide rectangular door.
As you approach, the door slides open automatically. To the left of the entrance sits a second regular chest.
Third chest
Use the teleporter on the second floor of the Isolated Zone. Directly opposite the spatial anchor, near a potted plant, the third chest awaits.
Fourth chest (battle)
From the previous treasure room, turn right, then left and descend the stairs.
Proceed left at the end of the corridor. A valuable chest is guarded by sting bugs. Include Quantum or Imaginary Path characters to quickly exploit enemy vulnerabilities.
Fifth chest
Access the southern spatial anchor on the second floor of the Isolated Zone. Turn left and step into a small room.
There is a regular box near a potted plant and some storage boxes.
Sixth chest
From the previous room, turn right and descend the stairs.
Then turn right again and enter the hexagonal door.
Move forward through the corridor to its end. A regular chest sits to the left of a large wall monitor.
Seventh chest
Return to the spatial anchor perched at the top of the map. A hexagonal door lies nearby.
Enter it and turn right. Another treasure room waits in the corner.
Eighth chest
Use the northern spatial anchor. Climb the short stairs opposite the teleporter.
At the top, turn right and enter the hexagonal door.
Advance along the hallway. Beware of stinging beetles that sometimes emerge from transparent wormholes. When they appear, quick, decisive attacks with Quantum or Imaginary Path characters are effective.
Defeat the enemies or dash past them to reach the chest, which sits in a right-hand recess.
Ninth chest
From the previous chest, proceed to the end of the hallway where a rectangular door opens automatically.
Enter, then turn left. A regular chest rests in the corner.
Tenth chest
From the previous treasure room, turn right and descend some stairs.
Enter the hexagonal door. The tenth chest sits behind a blue partition that opens automatically, with the box tucked under a hanging wall shelf.
Eleventh chest (piggy bank)
In addition to ordinary and valuable chests, the Isolated Zone houses a piggy bank. Defeating it yields 60 star jade.
Teleport to the north dimensional anchor on the second floor of the Isolated Zone and enter the wide rectangular door on the left. The pig runs down the hallway on the left.
Approach quickly to stop it from escaping. If Topaz is on the team, switch them in to keep the pig in place. Include characters from Fire, Imaginary, Physical, or Quantum paths; they help break the pig’s vulnerability.
Twelfth Chest (Puzzle)
Return to the travel point and enter the square door, which opens into a long, narrow hallway.
Advance along the passage until a hexagonal door appears on the left. Step through it.
Step on a sequence of glowing tiles in a specific order to unlock the chest. The required route is shown in a corresponding screenshot.
Thirteenth chest
Use the northern teleporter and retrace the hallway. Enter the hexagonal door on the right.
Near the supply boxes to the left sits the last regular chest.
What rewards can you get?
Collectively, the chests yield roughly 160 star jade. The treasure rooms also hold hertariums exchangeable for rewards at the station’s in-game store. Valuable chests contain relics that assist when leveling up characters.
