Understanding the Chrysalis of Broken Dreams phase
When Eclosioner enters the "Chrysalis of Broken Dreams" mode, it flies higher and summons mini vortexes on the battlefield. A red warning circle appears just before vortex activation; quickly moving out of this area helps avoid damage.
In this state, focus attacks on the four wings. Each wing has armor that you must break by dealing sustained damage. Once all four wings are broken, the boss becomes vulnerable with an exposed weak point. This is your opportunity to deal heavy damage and push towards victory.
Eclosioner Boss Guide: Step-by-step
Step 1: Prepare for the fight
Equip characters with strong ranged weapons and boost mobility stats. Learn the boss's location in Eastern District Icelake and make sure your team is suitably leveled (around level 30).
Step 2: Engage and observe attack patterns
Begin the battle by maintaining distance. Eclosioner uses many quick, targeted attacks and flight maneuvers. Keep moving, dodge frequently, and study the timing of its attacks to anticipate its next moves.
Step 3: Watch for Chrysalis of Broken Dreams phase
When Eclosioner ascends and activates this phase, it summons mini vortexes with red circle indicators signaling their activation zones. Quickly move out of these circles to avoid damage.
Step 4: Target the four wing armor pieces and exploit the exposed weak point
During the Chrysalis phase, target and break Eclosioner’s four protective wings with sustained ranged attacks while staying mobile to avoid damage. Once all wings are destroyed, its weak point is exposed—focus quick, precise attacks on it to deal heavy damage while continuing to dodge.
Step 5: Repeat phases and finish the fight
Eclosioner will cycle through flight and vulnerable phases. Repeat dodging vortexes and breaking wings to whittle down its health until defeated.
Tips for defeating Eclosioner
- Always respond to red circle indicators by quickly moving away.
- Use dodge rolls or skills to evade wide-range slashes and fast attacks.
- Maintain distance to improve your reaction window.
- During the Chrysalis of Broken Dreams phase, stay at a safe distance after breaking the wings, as Eclosioner often summons mini vortexes that pull you in—proper positioning helps avoid getting trapped and taking continuous damage.
