The Eclosioner is a boss that first appears in the Noctoyager Chapter 1! It is located upper left at the top part of Eastern District Icelake's map.

| How to Beat Eclosioner |
|---|
Eclosioner is a boss that uses a lot of flight movement throughout the battle. It is recommended that players speedily use ranged attacks for this boss fight.
When Eclosioner uses the Chrysalis of Broken Dreams state, the boss is vulnerable to taking hits from each of the four wings.
After taking down the wings, players are given the chance to aim for the Weakness Exposed point. Attack the boss while it is down to deal heavy damage!
| This move lets Eclosioner fly higher off the ground and it is the only state where her wings are exposed to take damage. She also summons mini vortexes on the battlefield in this state. |
|
| How to Dodge | There will be a red circle indicator before the vortex activates. Players can avoid the vortex by leaving the circle as soon as it targets them. |
|---|---|
| Eclosioner will target the player multiple times and try to land an attack on them. The indicator has a short timeframe since the attacks are quick. |
|
| How to Dodge | Players need to dodge fast and leave the area of each indicator as soon as they can. |
|---|---|
| The boss also uses normal attacks frequently. Players may also get hit by a wide ranged attack or a large slash. |
|
| How to Dodge | It is best to increase distance and use the dodge action, due to these attacks covering a wide area. |
