Walkthrough Tips

Beware of Surprise Attacks

Inside the Manor, you cannot move the camera freely. You'll be viewing the screen from a mostly fixed position, making it difficult to notice enemies outside your field of view. Proceed with caution, being mindful of enemies in your blind spots.

Walkthrough Tips

Dark Phantasm is Recommended for Group Fights

Inside the Underground Facility, large groups of enemies often spawn in narrow areas. If you get surrounded, your HP can be depleted in an instant. It's recommended to use a charged Dark Phantasm to avoid being swarmed by weaker enemies.

Be Careful Not to Miss Anything

The section from the start of Part 2 to the Underground Facility cannot be replayed after clearing it. Therefore, if you miss items like Words, they will be permanently lost. While this doesn't affect game progression, completionists should be careful.
