Read Messages From Fiona the Comms Officer
You will receive a message from Fiona, the Comms Officer, asking you to retrieve the research samples.
Go to the Target Location and Defeat the Landbreakers
Follow the guide to the target location and clear out the Landbreakers. Once they are all defeated, you can move forward.
Proceed Further to Meet Up With Rossi
Continue ahead to meet Rossi, who is also on a mission to retrieve the research samples. You will team up to search for them together.
Follow Rossi and Search for Clues
Follow the guide and investigate the red tracks while heading to the east side of the Mining Camp. This area was previously inaccessible, but you can enter after speaking with the children.
Accept the Request from The "King of Brickyland"
Head to the back of the area, where the "King of Brickyland" will ask you to bring two treasures.
Head to the North Side of the Temporary Stockpile
After accepting the king's request, head to the north side of the Temporary Stockpile. Speak with the Duchess of Windbell, then climb to the top of the container to retrieve the Holy Sword.
Move the Crane and Use the Jump Pad
To get the Holy Sword on top of the container, you need to use a jump pad, but the path is blocked by a container. You can move forward by operating the crane with the nearby control panel.
Capture Originium Slugs
Next, head west from the transfer device in the Old Mines to meet the Duke of Clockwork. After the conversation, the Originium Slug Chase challenge will begin, and you’ll receive a shield upon clearing it.
Chase the Originium Slugs One by One
In the Originium Slug Chase, follow the fleeing slugs and watch where they stop. There is plenty of time, so focus on catching them one at a time.
Return to the East Side of the Mining Camp
When you return to the east side of the Mining Camp, a cutscene will trigger, and you’ll need to rescue the king who fled into the depths of Brickyland. It takes about 30 minutes to clear, so make sure you have enough time before starting.
Party Members Can Be Selected
Brickyland is a dungeon where enemies will appear. The Endministrator and Rossi are fixed party members, and the remaining two can be freely chosen, so bringing well-trained characters will make your run much smoother.
| Tip! | If you want a more role-playing experience, you can choose not to fill the free slots. |

Follow the Guide to Reach the Depths
Inside the dungeon, you can mostly follow the guide to move deeper. The enemies along the way are around Lv 40 regardless of your Exploration Level.
Merry-Go-Round Activation Order
To activate the merry-go-round along the way, you need to trigger the switches in this order: Originium Slug → Long-ear → Tuskbeast.
Since Industrial Explosives cannot be used in the dungeon, climb the ledges to reach each switch and activate them with attacks.
Battle Landbreakers in the Depths
Once you reach the depths of Brickyland, you’ll face 8 Landbreakers. Watch out for attacks from the boss, Bonekrusher Siegeknuckles, and take them all down.
Finish the Conversation to Clear
After defeating the boss, the mission will be cleared once the conversation ends. When you return the Holy Sword and shield to the rescued king, he will reward you with a red diamond (research sample).
Boss Battle Strategy and Tactics
Deal With Smaller Enemies First
During the boss fight, it’s best to take out the smaller enemies before focusing on the Bonekrusher Siegeknuckles. The boss's attacks have long wind-ups, and many can be interrupted with Battle Skills, so fighting it one-on-one makes the encounter much easier.
Create Distance When Arm Turns Red
When the Bonekrusher Siegeknuckles's arm turns red, it's a sign of a powerful attack. Back off briefly and wait for it to return to normal before going back in to deal damage safely.
