In Wuthering Waves, Nightmare Tempest Mephis can serve as an excellent substitute for the primary 4-slot Echo of Electro characters. This boss not only boosts your stats but also enhances damage rotations, making it a more potent option than its standard counterpart. Plus, it's visually more appealing with its shinier appearance.
While most Nightmare Echoes in Wuthering Waves are easily accessible, unlocking Nightmare Tempest Mephis requires a bit more effort. Here's how you can get to this formidable boss.
Where to Find Nightmare Tempest Mephis in Wuthering Waves
You'll find Nightmare Tempest Mephis in a large, circular arena located in the Shores of Last Breath within the Fagaceae Peninsula. However, accessing this boss involves a couple of prerequisites.
First, you need to complete the "Where Winds Return to Celestial Realms" quest in WuWa. This exploration quest takes place in the Shores of Last Breath and focuses on combat. While you can complete it in one go, it's quite time-consuming. Completing this quest is crucial as it unlocks the arena where Nightmare Tempest Mephis resides.
Next, you must locate all the Dream Patrols in the Shores of Last Breath. Simply discovering them, so they appear on your map, is sufficient. You don't need to complete the patrols. Once all Dream Patrols are found, 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 or not to use Nightmare Tempest Mephis depends on the stats you obtain from 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 beneficial for all Electro damage dealers, whereas the Empyrean Anthem set is ideal for characters like Yinlin and Yuanwu who can perform Coordinated Attacks.
Moreover, Nightmare Tempest Mephis' transformation attack differs from the regular version, potentially improving certain rotations for specific characters or teams. Coupled with the passive Electro DMG bonus, Nightmare Echoes are definitely worth considering.
However, the priority should always be on securing Echoes with superior stats. If your Nightmare Tempest Mephis has lower stats than a regular one, sticking with the standard variant might yield better overall results.
