The Crystalophile is a boss that first appears in the Noctoyager Chapter 1! It is located underground at the top part of Glevum Pit's regional map.

| How to Beat Crystalophile |
|---|
Crystalophile has attacks that cover a wide range when in close combat. Using ranged attacks or a character that specializes in ranged combat can help deal additional damage.
Players must break all four arms of the Crystalophile. This will break the stance bar of the boss and leave it open for the main attack.
Once all arms are taken down, it will be the player's chance to hit the exposed forehead and deal big damage to the boss!
| Crystalophile will move from one end to the other in a targeted straight line. |
|
| How to Dodge | Stay outside of the boss' targeted line of sight, since Crystalophile covers a wide area when landing. |
|---|---|
| Crystalophile has another pounce attack. The boss jumps to where the player is and will prepare an attack close to where the it landed. |
|
| How to Dodge | The player must time their movement to steer clear from Crystalophile when it pounces on the player. |
|---|---|
| Crystalophile will target the area in a wide outward attack for three times, with each row getting wider. |
|
| How to Dodge | Players can move out of Crystalophile's target zone and attempt to attack its current blind spots. |
