How to light nightmare lantern?

Learning how to light nightmare lantern in Hollow Knight is essential for progressing through the challenging Grimm Troupe DLC content. The nightmare lantern serves as a crucial element that initiates one of the game's most memorable questlines.

Finding the Nightmare Lantern

The nightmare lantern is located in the Howling Cliffs area, specifically in a hidden chamber accessible through careful exploration. You'll need to navigate through several platforming challenges and defeat some enemies to reach this mysterious artifact.

How to Light the Lantern

To light the nightmare lantern, you'll need to interact with it using your Dream Nail ability. First, ensure you've obtained the Dream Nail from the Resting Grounds area earlier in your playthrough. Approach the lantern and use the Dream Nail on it - this will trigger a dramatic cutscene and summon the Grimm Troupe.

What Happens Next

Once lit, the nightmare lantern transforms the surrounding area and opens up the Grimm Troupe tent in Dirtmouth. This action begins the extensive Grimm Troupe questline, introducing new NPCs including Grimm himself, Divine, and Brumm. You'll gain access to unique charms, boss battles, and story content.

Important Considerations

Lighting the nightmare lantern is irreversible and will significantly alter your current playthrough. The Grimm Troupe content includes challenging boss fights against Troupe Master Grimm and potentially Nightmare King Grimm, so ensure you're prepared for difficult encounters.

The questline also involves collecting Nightmare Flames scattered throughout Hallownest, requiring thorough exploration of various areas you may have already visited.

Successfully lighting the nightmare lantern opens up some of Hollow Knight's most rewarding and challenging content. Ready to face the Grimm Troupe and discover what otherworldly secrets await in their crimson tent?
