Wuthering Waves: Jianxin Weapon, Echo, and Team Composition Recommendations
Skill Introduction

Normal Attack—Basic Attack
Resonance Skill—Skill
Resonance Circuit—Energy bar and the linkage between skill and attack keys
Resonance Liberation—Ultimate
Variation Skill—Triggered upon entry
Extension Skill—Triggered upon exit, for the next entry or within the team
Characters triggering Extension Skills add buffs
Note: Extension Skills—Triggered upon exit, giving the enemy one last hit before leaving (currently only these two effects)
Resonance Skill (partial effects)
Reduces damage by 50%
So, the recommended main Soul Weapon is: Bell of Claymore
Reducing damage by 100% lets you peacefully play Tai Chi (Playing Tai Chi refers to Resonance Circuit)
Playstyle: Start with the Soul Weapon skill + Resonance Circuit
During this time, you can use the Resonance Skill. If you want to use it, switch the skill keys for easier operation
Priority on Attack stat

Soul Weapon Recommendation
Because Jianxin’s shield relies on Attack
I suggest aiming for these two sets
Just two pieces for each set are enough
Of course, you can also choose the Hidden World’s Horizon five-piece set (I recommend this)
Oh right! The Bell of Claymore’s damage reduction effect, as long as within the time limit, if the number of damage resistances is less than 3 times, the next character to enter can also benefit from it!
Weapon Recommendation
The shield value is linked to Attack, so for a four-star, I recommend this one
Team Composition Recommendation
Jianxin: Shield plus healing, Extension Skill: Ultimate damage increase by 38%, for 14 seconds.
Main DPS + Jianxin, is totally enough.
For the main DPS, I recommend Akaneko, as Akaneko’s Resonance Circuit has a high frequency of activation.
Explanation of Resonance Circuit
Heavy Attack: Segmental damage reduction by 70%, the second segment inflicts damage equal to the Ultimate damage.
Ultimate followed by Heavy Attack: Segmental damage reduction by 70%, the second segment inflicts damage equal to the Ultimate damage.
So, the Resonance Circuit deals Ultimate damage.
Explanation of Resonance Liberation (Ultimate)
Enhances [Normal Attack] = Normal Attack damage
Enhances [Skill] = Skill damage
Enhances [Heavy Attack] = Heavy Attack damage
Enhances [Evasion Counterattack] = Evasion Counterattack damage
So the core is still to fill up the [Energy bar] and unleash the [Resonance Circuit]
