Key Tips

  • You will need Wolf Statues to unlock the Wraithstone. You must destroy all four before it’s accessible.
  • Artillery Cannons hide both gold and passageways. You need to shieldbash them to reveal what’s hidden.
  • Flooding mechanics appear twice in this chapter. They help float gold chests and unlock otherwise unreachable paths.
  • Pay attention to environmental cues—walls with blue markings, monster arms, and oddly-placed trees often hide something behind or above.
  • Combat zones often end with collectibles or open up access to hidden rooms. Don’t skip cleanup.

Why Secrets Matter in This Chapter

You will collect more than just gold here. Each secret is tied to something unique: a piece of lore, a combat challenge, or an upgrade. Some are required to complete challenges like Master Hunter, which involves targeting a Hell Fighter mid-flight during the dragon segment.

You can revisit this chapter through Chapter Select without losing progress on your main game. Items already picked up remain collected, so use that to your advantage if anything feels out of place.
