Best Teams to Defeat the Millennial Pearl Seahorse

Recommended Team Composition for the Millennial Pearl Seahorse

Ayaka Mono Cryo Team
Ayaka Image Ayaka Shenhe Image Shenhe Kazuha Image Kazuha Diona Image Diona

Ayaka is the best Cryo DPS against the Millennial Pearl Seahorse! Her Cryo-infused attacks, along with Skill and Burst, can quickly break the Electro Shield and the pearl on its chest. This team can also clear the Resonant Coral Orbs fairly quickly, especially using Ayaka's dash infusing Cryo to break them.

Bloom and Hyperbloom Team

Hyperbloom Team
Alhaitham Image Alhaitham Nahida Image Nahida Xingqiu Image Xingqiu Raiden Image Raiden

You can also use Bloom or Hyperbloom teams against the Millennial Pearl Seahorse! Though not as potent to break the Seahorse's Pearl, use Dendro and Hydro to deal consistent damage whenever it's on the ground. .

Vaporize Teams

Vaporize Team
Yoimiya Image Yoimiya Zhongli Image Zhongli Yelan Image Yelan Bennett Image Bennett
Yoimiya Image Yoimiya Xingqiu Image Xingqiu Yun Jin Image Yun Jin Bennett Image Bennett

The Millennial Pearl Seahorse can be pretty hard to focus its attacks. Its Shock Dive Attack and Fontemer Hoarthunder Strike in particular makes it hard to hit attacks and skills.

The Pyro and Hydro damage from Yoimiya's Skill and the Hydro Characters' Burst will have consistent DPS when attacking. The other characters are for supporting and boosting Yoimiya's attacks as much as possible.

Best Free-to-Play Team

Traveler (Dendro) Image Traveler (Dendro) Xingqiu Image Xingqiu Xiangling Image Xiangling Layla Image Layla

While both Hydro and Dendro Traveler would make for a good base for your team, the Dendro Traveler has an edge to due to Aggravate and Spread damage. It also has access to Bloom with Xingqiu and Xiangling, and even Hyperbloom due to the Millennial Pearl Seahorse's Electro affinity.
