• Should You Use Nightmare Tempest Mephis?

Nightmare Tempest Mephis offers a significant upgrade over standard 4-slot Electro Echoes in Wuthering Waves. It boosts stats and can enhance damage rotations. The aesthetic upgrade is a bonus!

While all Nightmare Echoes provide similar benefits, accessing Nightmare Tempest Mephis requires specific steps. This guide details the process.

Where to Find Nightmare Tempest Mephis in Wuthering Waves

This challenging boss resides in a large, circular arena within the Shores of Last Breath, Fagaceae Peninsula. However, access is conditional.

First, complete the "Where Winds Return to Celestial Realms" quest. This exploration quest, located in the Shores of Last Breath, is combat-focused and requires time to complete. Completing this quest unlocks the boss arena.

Second, locate all Dream Patrols in the Shores of Last Breath. Completion isn't necessary; simply discovering them on your map suffices. Upon discovering all patrols, a message confirms Nightmare Tempest Mephis' appearance, making the boss accessible at the location shown above.

Should You Use Nightmare Tempest Mephis?

The optimal choice depends on your Echo stats and desired character build. Nightmare Tempest Mephis inherently grants bonus Electro DMG when equipped in the main Echo slot, appearing in either Void Thunder or Empyrean Anthem Sonata sets. Void Thunder generally benefits all Electro damage dealers, while Empyrean Anthem Sonata is better suited for characters utilizing Coordinated Attacks (like Yinlin and Yuanwu).

Furthermore, its unique transformation attack differs from its regular counterpart, potentially improving rotations for specific characters or teams. This, combined with the passive Electro DMG bonus, makes Nightmare Echoes valuable for most characters.

However, prioritize Echoes with superior stats. If Nightmare Tempest Mephis possesses inferior stats to a regular Echo, using the regular variant may yield better results.
