Must-Have C3 Echoes in WuWa — Strong Enough to Rival C4!

In Wuthering Waves, the Echo system plays a major role in shaping each character’s power. Echoes are divided into three tiers — C1, C3, and C4 — with C4s usually being the strongest and the go-to choice for the main slot. However, not all C4s dominate the field.

A few outstanding C3 Echoes stand out for their unique effects, incredible synergy, and multi-set bonuses, making them not only highly efficient but in some cases strong enough to replace C4s as your main Echo. Let’s take a closer look at these game-changing C3s!

Capitaneus

Class: Elite Cost: 3

Known as the “C3 that kicked the C4s,” the Capitaneus is the pioneer that proved a C3 can outperform a C4 in the main slot. When equipped as the primary Echo, it boosts Refraction Damage by 12% and Heavy Attack Damage by 12%, often outperforming Nightmare: Mourning Aix in real combat scenarios.
Capitaneus also unleashes a fast, multi-hit Aero strike that chains seamlessly into combos, keeping your DPS rotation smooth and efficient.
This Echo pairs perfectly with Zani, offering ideal synergy for her playstyle. Even more impressive, the Envoy combines three Echo set effects in one — Celestial Light, Gusts of Welkin, and Windward Pilgrimage. That means one investment benefits multiple team setups — an S-tier efficiency pick.

Kerasaur

Class: Elite Cost: 3

Next up is the Kerasaur. Though rarely used as a main Echo for now, it offers Aero Damage Bonus and Resonance Liberation Damage Boost, which may become invaluable in future content or for upcoming characters. After all, developers rarely design C3 Echoes with such bonuses “just because.”
Though rarely used as a main Echo for now, it offers Aero Damage Bonus and Resonance Liberation Damage Boost, which may become invaluable for future Aero-focused characters. Its aggressive moveset mimics the skill rhythm of aerial DPS units, giving it surprising synergy with hybrid playstyles.
Like the Envoy, Kerasaur carries three set effects: Windward Pilgrimage, Flaming Clawprint, and Flamewing's Shadow. But what truly sets it apart is its battlefield dominance — if you encounter one in the wild, it’s often better to avoid a fight unless you’re ready.

Corrosaurus

Class: Elite Cost: 3

The Corrosaurus. As another elite C3 Echo, it grants +12% Fusion Damage Bonus and +20% Echo Skill Damage Bonus when equipped in the main slot — a perfect match for Galbrena.
The Corrosaurus’s signature skill emits a blast of molten energy, spreading burn effects that amplify Fusion rotations. Unlike the previous two, this Echo only combines two set effects: Flaming Clawprint and Flamewing’s Shadow. While slightly less flexible, its raw offensive potential makes it a must-have for burst-oriented builds or heat damage specialists.

In coordinated teams, it can even outperform C4s by delivering faster skill cycles and superior burst stacking.

Conclusion

These C3 Echoes prove that rarity doesn’t define strength. Whether you’re optimizing Zani’s Aero DPS, preparing for future Fusion or hybrid characters, or simply seeking the best value-for-investment setup, these Echoes deliver C4-level power at a C3 cost — a perfect example of how strategy and understanding can overcome sheer rarity.
