Quest Details

• Chapter: 12, The Abyss

• Arc: The Final Battle

• Quest Type: Main Story Quest

• Previous Quest: Precise Execution

• Next Quest: Departure of the Brave

Objectives

• Push through enemy lines to reach the Blackstar weapon emplacement

• Destroy the Blackstar's defensive shielding

• Defeat the Blackstar boss (Ultimate Weapon encounter)

• Regroup with the main allied force after the advance stalls

Boss Fight: Blackstar

The Blackstar serves as the major combat encounter of this quest. It is a heavily armored weapon emplacement that fires devastating attacks across the battlefield. Players should focus on destroying the outer shielding first, then target exposed weak points. Use Axiom Force abilities to reveal vulnerable sections, and dodge the sweeping energy attacks it unleashes periodically.

Known Bug

Ballista Health Bug: A known issue exists where retrying or abandoning the Ultimate Weapon fight after depleting the Blackstar's health causes the Blackstar's health bar to not fully recover on the retry. This can make subsequent attempts easier or harder depending on the state. This bug has been documented on the official Steam Community page. Players should be aware that the boss health may behave unexpectedly if they restart the encounter.

Walkthrough

After completing Precise Execution, the advance continues deeper into enemy territory. The name of this quest reflects the reality that progress has stalled; the allied force must regroup and find another way forward. Engage the Blackstar using a combination of ranged weapons and close-range abilities. Damiane's long-range skills can be especially useful during this fight.

Tips

• Bring plenty of healing items. The Blackstar fight is lengthy and punishing.

• If the ballista health bug occurs, you may want to load a manual save rather than using the retry option.

• Use environmental cover during the approach to avoid taking unnecessary damage from ranged attacks.
