- Insects will appear after Arlen has taken damage and start healing him, take them out quickly.
- Watch out for the tentacles as they alternate between swinging and slamming down on your location.
- Arlen will shoot projectiles on occasion, when you notice him rearing up, move out of the way.
- After defeating Arlen, a tougher version of this boss can be fought, Echo of Arlen. The door to this fight is on Apexion, close to the starting point.
