Nightmare Echoes are enhanced versions of previous bosses in Wuthering Waves, offering powerful rewards. Here’s how to unlock and farm each one.

Unlocking Most Nightmare Echoes

To gain access to five Nightmare Echoes, complete the Dream Patrol 1 quest.

• Head to the rooftop in the southwest area of Ragunna City and locate the white cat.

• Interact with it to begin the quest.

• Upon completion, you’ll unlock:

  • Nightmare: Feilian Beringal
  • Nightmare: Thundering Mephis
  • Nightmare: Impermanence Heron
  • Nightmare: Mourning Aix
  • Nightmare: Inferno Rider

Before fast-traveling to any of these bosses, you must first discover their locations manually on the map. Each Nightmare Echo respawns approximately 30 seconds after being defeated. Note that they do not drop Ascension materials and can be fought without consuming Waveplates.

How to Unlock Nightmare Tempest Mephis

Accessing Nightmare Tempest Mephis involves several stages.

Clear the Storm

• Complete three stele puzzles located in the Fagaceae Peninsula.
• Doing so triggers the quest Where Wind Returns to Celestial Realms.
• Successfully completing the quest lifts the storm barrier covering part of the region.

Stand within the designated altar zones and defeat waves of enemies until your progress reaches 100%.

Battle the Lumiscale Construct

• Locate the Lumiscale Construct near the Shores of Last Breath.
• Reduce its health to 65%, which causes it to flee.
• Pursue it into the nearby ruins and engage again.
• During the second phase, a variant called the Dragon of Dirge will appear—defeat it to proceed.

Discover Dream Patrol Arenas

• Explore and locate all four Dream Patrol arenas scattered across the Fagaceae Peninsula.
• You don’t need to complete the challenges inside—just discovering them is enough.
• Once all four are found, Nightmare Tempest Mephis will appear at the Shores of Last Breath.

How to Unlock Nightmare Crownless

This is the most involved unlock process.

Begin the Quest of Faith

• Travel to the northwestern section of Penitent’s Rest.
• A brief interaction starts the Quest of Faith side quest.

Fight in the Ruin Arenas

• Enter and clear four ruin arenas by defeating all enemies.
• Damage can only be dealt while standing in the illuminated zones from purple torches.
• In later arenas, use Fae Ignis enemies to reignite torches when they go out.

Gather the Writings

• After each battle, collect the glowing script fragments from the ground.
• Finishing all four arenas and collecting every writing completes the quest.

Find the Dream Patrol Arenas

• After completing Quest of Faith, the white cat gives new information about Dream Patrol locations.
• Discover all four arenas in Penitent’s End to trigger the appearance of Nightmare Crownless.
