| Let's go then. | Empathy | +3 |

Follow the quest marker to get to the entrance to Glevum Pit. You will eventually end up inside a cavern on the side of a mountain. However, the doors are broken, and the Phoxhunter will be unable to open it by force.

Use the large crate to your left to find another way into Glevum Pit. Jump onto the crate and climb into the small opening. As soon as you emerge, a few Filthoids will attack you. Defeat them and then proceed until you find a giant cargo lift.
When you reach the Pit, Snow will lead you to crates of abandoned items and powder kegs. After reading a journal left behind by a Phoxhunter, you will bring the kegs with you.
Move on to the large open space in the Pit. There will be several Filthoids coming in from all sides. Defeat them so you can safely move on.
Once you're ready to move further in, you'll find that another set of automated doors is broken. Place a powder keg before the doors and use a ranged weapon to blow it up.

Go through the now-opened doors and toward a towering crystal growth. Leave a powder keg by the crystal and blow it up. Doing this will also provoke the Filthoids in the area. Be prepared for a short battle.

Keep following the quest marker and head deeper into Glevum Pit. Many Filthoids will be lying in wait so expect long fights ahead.
A cutscene will begin when you reach far enough into the pit and into the territory of the Crystalophile.
If you don't want to fight all of the Filthoids, press on and keep following the quest marker.

The Crystalophile is a boss you encounter deep in the pit. For this battle, you will use Psyche to fight the Crystalophile. Target its weak points and quickly dodge its sweeping attacks.
After defeating Crystalophile, you will obtain the Crystallo of Stella.

After the boss fight a cutscene plays wherein you meet Outsider, a Phoxhunter who has also been searching for the Crystallo of Stella.
| Prompt 3 | ||
|---|---|---|
| Please give it back! That Crystallo is important to Vita, and to all of us! | ||
| Response | Impression | Points |
| We defeated that Filthoid. Give it back. | Morality | +3 |
| If there's no such thing as dibs, that means we can just beat you up and take the Crystallo back. | Chaos | +3 |
Teleport back to the city gates. Henrik will come to greet you in a short cutscene, pulling Psyche away from the group and ending the subquest.

Crystalophile appears as a story boss in the quest Crystallo of Stella in Noctoyager Act 1. Crystalophile is a highly mobile boss that uses a mix of long-ranged and AoE attacks.
