Best weapons to build Galbrena in Wuthering Waves

Galbrena's strongest weapon in Wuthering Waves, the signature pistol Lux & Umbra, increases her ATK by 12%. Dealing Echo Skill DMG provides a 24% Heavy Attack DMG Amplification for six seconds. Subsequently, launching Heavy Attack will enhance her Echo Skill DMG by 24% for the same duration. When both effects are active, her attacks will ignore 8% of the target's DEF.
The Lux & Umbra clearly enhances Galbrena’s damage sources and allows her to pierce through an enemy’s resistance.
2) The Last Dance (5-star)

If you have Carlota’s signature pistol, use it to build Galbrena. The weapon provides a hefty CRIT DMG boost via the substat. She will further receive a 12% ATK boost from The Last Dance's passive.
Upon casting her Intro Skill or Resonance Liberation, Galbrena’s Skill DMG will be enhanced by 48% for five seconds. Although the unique effect of The Last Dance isn’t quite useful for the Resonator, she can still benefit from the massive stat boost.
3) Static Mist (5-star)

Static Mist is available on the standard banner in Wuthering Waves. Therefore, it is quite easy to access and gets the job done. Equip the Pistol on Galbena, if you have one lying around, and level it up to get the 24.3% Crit Rate from the subsidiary stat.
The weapon’s passive will boost her Energy Regen by 12.8% and offer a 10% ATK buff. You should also be able to inflict sufficient damage with Static Mist.
4) Solar Flame (4-star)

Solar Flame is the 4-star Battle Pass exclusive weapon that Galbrena can use. It is equipped with a 20.2% CRIT Rate, which is sufficient to balance her overall stat. Dealing Basic Attack or Heavy Attack DMG will increase her ATK by 2.2% and grant a 2.2% Heavy Attack DMG Bonus for up to four stacks.
Heavy Attacks are one of Galbrena’s primary damage sources. Any weapon that buffs the ability will always be useful.
5) Relativistic Jet (4-star)

Relativistic Jet is the most accessible pistol for DPS units, and Galbrena can use it too.
The weapon provides six Resonance Energy to the wearer. The character also receives a 10% ATK boost. Galbrene can trigger the buffs by casting her Resonance Skill.
