Best Shorekeeper teams

Sigrika Aero EchoSS

Best Aero team — top-tier in both single-target and multi-wave content with full Aero and Echo Skill buff stacking.

Augusta Electro SustainSS

Iuno's Heavy Attack buffs and Outro Skill amplification plug straight into Augusta's Heavy-Attack-driven Electro kit, and her healing plus stamina regen keep the rotation running without gaps; Shorekeeper's Liberation field adds continuous healing and a Crit buff so both units can commit fully to their Heavy Attack windows.

Zani FrazzleS

Phoebe is the premier Spectro Frazzle applier-amplifier for Zani; officially recommended pairing.

Jinhsi CoordA

Yinlin's coordinated attacks feed Jinhsi's Incandescence stacks for huge Liberation bursts.

Camellya Basic-AttackA

Sanhua's Basic Attack Deepen and fast Concerto let Camellya stay on field longer.
