How to Unlock Invisible Glyphs: Investigation
Complete Discovery and Wait For a Server Reset
You can unlock Invisible Glyphs: Investigation after completing the previous quest, Invisible Glyphs: Discovery, and by waiting for one server reset. Jouster sends you a message via Baker, which auto-starts the mission after reading it!

Invisible Glyphs: Investigation Walkthrough
Read Jouster's Message
After a server reset, read Jouster's message by opening the Baker menu and selecting Jouster's inbox to start the quest. He'll tell you about the discovery he's made about the special glyphs of Bonekrushers, as well as their interpretations and meanings.
Find Jouster
After reading his message, find Jouster on the exact location where you first met him. However, few paces away from the location, you'll receive a distress message that signals the security guard is in danger. Go to the Landbreaker Camp nearby afterwards.
Defeat the Landbreakers
Upon arrival at the Landbreaker Camp, you'll see a Mad Landbreaker Pyromancer in the middle of an open field, who's crazily screaming about the effects of the haze. Having been affected by the nearby Denstack, defeat the Landbreakers and interact with the Denstack Haze.
Follow the Landbreaker Graffiti
After the brief cutscene showing the glyphs, follow the Landbreaker Graffiti by going after the quest marker on your screen. Visiting the location of each graffiti does nothing to the quest, so the most efficient way at this point is to simply head to the marker until you find yourself at a Landbreaker encampment stationed right at the edge of a cliffside.
How to Break the Wall
There will be Landbreaker enemies here which you must defeat, and a breakable wall that blocks the way towards the hidden Landbreaker Camp. To break this wall, face the abandoned factory right across the cliffside encampment, and head inside one of the shelters, and extract a bomb from the Barrel of Originium!
Find a Way to Enter the Cave
Once you've walked deep within the hidden Landbreaker Camp, defeat all the nearby enemies and find a way to enter the cave. To enter the cave, suffuse yourself with Denstack Haze, and use the Bonekrusher glyphs as your guide!
Alternatively, you can refer to the image above to know the correct order of the lever mechanisms to enter the cave!
How to Find a Way to Enter the Cave
| How to Enter the Cave | |
|---|---|
| 1 |  To enter the cave, interact with the denstack haze to view the hidden Bonekrusher glyphs. |
| 2 |  The hidden glyphs should reveal themselves right in front of the three levers. Starting from the left lever, the glyphs that appeared are the Human Face, Treasure, and the Shovel glyphs. |
| 3 |  Following the clue from the note beside the cave entrance, pull the lever of the Human Face first, followed by the Treasure's, and the Shovel's. Doing so should open the cave entrance! |
Find Jouster
After opening the cave entrance, head in and find Jouster, who's currently locked inside an iron cage. Free him, then investigate the cave further to conclude the quest! The last quest of the series, Invisible Glyphs: Revelation, auto-starts after completing this quest!
