• Should You Use Nightmare Tempest Mephis?

Nightmare Tempest Mephis can be a fantastic substitute for the main 4-slot Echo of Electro characters in Wuthering Waves. This boss not only boosts your stats but can also enhance certain damage rotations significantly compared to its standard version. Plus, it boasts a more striking appearance.

While all Nightmare Echoes in Wuthering Waves offer similar bonuses, reaching Nightmare Tempest Mephis involves a few specific steps. Here's how you can unlock this formidable boss.

Where to Find Nightmare Tempest Mephis in Wuthering Waves

You'll encounter this boss in the expansive, circular arena located in the Shores of Last Breath within the Fagaceae Peninsula. However, accessing Nightmare Tempest Mephis requires completing a couple of prerequisites.

First, you need to complete the "Where Winds Return to Celestial Realms" quest in Wuthering Waves. This exploration quest takes place in the Shores of Last Breath and involves combat. While you can complete it in one go, it will take some time. Completing this quest is crucial as it unlocks the path to Nightmare Tempest Mephis' arena.

Secondly, you must locate all the Dream Patrols in the Shores of Last Breath. Simply discovering them and marking them on your map is sufficient; you don't need to complete the patrols. Once you've found all of them, a notification will inform you that Nightmare Tempest Mephis has appeared, and you can then challenge it at the location shown in the image above.

Should You Use Nightmare Tempest Mephis?

Whether you should use Nightmare Tempest Mephis depends on the stats of your Echo drops and the Wuthering Waves character you're building. When equipped in the main Echo slot, Nightmare Tempest Mephis grants a bonus to Electro DMG and can be part of either the Void Thunder or Empyrean Anthem Sonata sets. The Void Thunder set is ideal for all Electro damage dealers, while the Empyrean Anthem set is better suited for characters capable of Coordinated Attacks, such as Yinlin and Yuanwu.

Moreover, Nightmare Tempest Mephis' transformation attack differs from its regular counterpart, potentially offering improved rotations for specific characters or teams. Combined with the passive Electro DMG bonus, Nightmare Echoes are definitely worth considering for most characters.

However, always prioritize Echoes with superior stats. If your Nightmare Tempest Mephis has lower stats than a regular one, you might achieve better results by sticking with the standard variant.
