Sovereign Tower Dullahan Guide: How to Get Dullahan.

Short answer

The community roster reports that Dullahan appears only after Goberto dies. The report is useful because it gives players a concrete test, but it does not publish the full timing, location, or every prerequisite. Treat it as the first branch to reproduce, not as a guaranteed unlock code.

Before you trigger the route

Take a state note before the event that puts Goberto at risk. Record the day, active quest, Goberto's status, open table slots, and any recent rewind. Without that before-state, a later appearance or failure cannot be attributed to the trigger with confidence.

• Record Goberto's current status and relationship state
• Note the preceding quest, response, and assigned knight
• Keep one save or rewind point before the irreversible choice
• Capture the first scene in which Dullahan appears

After Goberto dies

Continue only far enough to see whether the game adds a new audience scene, roster entry, or recruitment lead. Do not assume that the first death animation is the unlock itself; the reported route may depend on a later cycle or follow-up scene.

• Check the Round Table and character records
• Look for a new audience request or map clue
• Compare the result after a rewind with the same preceding state
• Label the trigger as reproduced, player-reported, or still unknown

If Dullahan does not appear

Do not immediately publish a failed route as proof that the guide is wrong. Check the build, whether Goberto's death was the same event, whether a follow-up scene was skipped, and whether the table had room. These are investigation points, not confirmed extra requirements.

What a trustworthy unlock guide should say

A useful answer separates the observed trigger from the missing details. Publish the exact state you reproduced, the first visible Dullahan scene, and any conditions that changed between successful and failed tests. That gives players a route they can check after an update.
