Version: 2.7 | Last Updated: 2026-02-23 | Sources: Game8, Joytify, Ldshop, Gamerant

Overview

Qiuyuan is a 5-star Aero Sword character introduced in Wuthering Waves 2.7. He excels as a hybrid sub-DPS and support enabler, providing powerful Echo Skill DMG amplification and team Crit buffs through his unique Swordster's Soliloquy mechanic.

Why Qiuyuan is Top Tier

• 30% Echo Skill DMG buff to entire team (Bamboo's Shade)
• 30% Crit DMG buff from Liberation (scales with his Crit Rate)
• Short on-field time with fast rotations
• Essential for Echo Skill-centric teams (Galbrena, Phrolova, Cantarella)
• Heavy Attack DPS potential at S3+

Key Mechanics

Swordster's Soliloquy

• Resource gauge built by: Basic Attacks, Intro Skills, Skill usage, counters
• At 400+ points: Activates Bamboo's Shade state
• At 600 points: Enables enhanced attacks and full team buffs
• Unlocks Heavy Attack amplification and Crit-based team buffs

Liberation Crit Buff

• Grants team 2% Crit DMG for every 1% Crit Rate above 50%
• Maximum buff: 30% Crit DMG at 65%+ Crit Rate
• This makes building Crit Rate essential for support value

Best Echo Sets

1. Law of Harmony (3pc) + Sierra Gale (2pc) - Best in Slot

• Law of Harmony: Heavy ATK DMG and Echo Skill DMG buffs
• Sierra Gale: Aero DMG bonus for personal damage
• Why: Maximizes both team support and personal output

2. Moonlit Clouds (5pc) - General Support Build

• Provides +15% ATK buff on Outro to next character
• With Impermanence Heron echo for additional ATK support
• Best when using Qiuyuan purely for quick swap buffing

3. Sierra Gale (5pc) - DPS Build (S3+)

• Full Aero DMG focus for personal damage
• With Nightmare: Feilian Beringal main echo
• Only recommended at Sequence Node 3 or higher

Team Compositions

Echo Skill Team (Best)

• Qiuyuan + Galbrena + Verina - Echo Skill focus
• Qiuyuan + Phrolova + Support - Echo amplification
• Qiuyuan + Cantarella + Healer - Echo Skill synergy

Universal Crit Support

• Qiuyuan + Any DPS + Verina - General Crit DMG buffing
• Works when DPS doesn't specifically need Echo Skill buffs

Aero Resonance

• Qiuyuan + Jiyan + Support - Aero element synergy
• Elemental resonance bonus

Skill Priority & Rotation

Skill Upgrade Order

1. Forte Circuit - Core to damage profile and buffs
2. Resonance Liberation - Team Crit DMG utility
3. Resonance Skill - Extra damage
4. Basic Attack - Lower priority
5. Intro Skill - Supportive

Basic Rotation

Intro → Build Soliloquy (Basic Attacks) → Skill → Echo Skill → Liberation → Heavy Attacks → Outro

Quick Swap Rotation

Intro → Skill → Echo → Jump → Basic ATK → Outro

Use quick swap when DPS needs maximum field time.

Gameplay Tips

1. Hit 65% Crit Rate - Every point above 50% adds 2% Crit DMG for team
2. Short Field Windows - Quick rotations, don't overstay
3. 130% Energy Regen - Ensures Liberation every rotation
4. Echo Skill Timing - Use near Liberation for buff stacking
5. S3+ for DPS - Before S3, prioritize support builds

Sequence Nodes Priority

Node	Value	Effect
S0	★★★★☆	Complete support kit
S1	★★☆	Minor personal damage
S3	★★★★	Unlocks DPS viability
S6	★★★★☆	Extended buffs and damage

Sub-DPS vs DPS: Which Build?

Sub-DPS / Team Utility (Recommended)

• Law of Harmony + Sierra Gale
• Focus on Crit Rate → Energy Regen → Crit DMG
• Best for most players and team compositions
• Aligns naturally with his kit

Heavy Attack DPS (S3+ only)

• Sierra Gale 5pc with Feilian Beringal
• Focus on Crit Rate → Aero DMG → Heavy ATK DMG
• More investment required, tighter execution
• Only viable with higher Sequence Nodes
