Shared Team Members

With Kokomi

Xingqiu and Kokomi form a nearly unstoppable double Hydro core that provides both high damage reduction and exceptional healing. Xingqiu's Raincutter swords provide consistent Hydro application and single-target damage, while Kokomi offers AoE Hydro and sustained team healing. Together, they ensure permanent Hydro Resonance and excellent energy generation for the entire party.

With Yelan

Xingqiu is the premier partner for Yelan in 'Double Hydro' teams, where their combined Hydro application and damage are unparalleled. Their presence together lowers each other's Energy Recharge requirements and provides Hydro Resonance, which boosts Yelan's HP-scaling damage. This duo is a staple for high-end teams that focus on vaporize or extreme raw Hydro DPS.

With Kokomi

Kazuha provides Kokomi with a massive Hydro DMG bonus and 40% Hydro RES shred via Viridescent Venerer, which is essential for maximizing her damage in Mono-Hydro or Taser builds. His grouping pulls enemies into Kokomi's jellyfish range, ensuring they receive consistent damage and Hydro application. This synergy significantly enhances Kokomi's effectiveness as an on-field driver.

With Yelan

Kazuha is a key force multiplier for Yelan, offering a large Hydro DMG bonus and Hydro RES shred that greatly amplifies her high personal damage. His grouping ensures her Elemental Skill and Burst hit as many targets as possible, while his personal damage also benefits from any team buffs. He is an essential support for maximizing Yelan's contribution in any Hydro-related team.
