Lux & Umbra Weapon Guide: Best Pistol for Galbrena in Wuthering Waves

fragster Ahsan Kabir 7. October 2025

The Lux & Umbra is a five-star pistol in Wuthering Waves designed as the signature weapon for Galbrena. This pistol is known for its high attack stats and it’s unique passive ability that works on enhancing Echo Skill and Heavy Attack damage. Due to this, it’s one of the best weapons available for players who want to do consistent heavy damage in a build.

Weapon Overview

Lux & Umbra has a base attack of 587 at level 90, combined with a secondary stat of 48.6% Critical Damage. Having a combination of solid attack damage and Critical Damage gives more stability to players looking for higher burst potential. The Lux & Umbra lends itself as a reliable weapon in combat situations no matter what the combat situation is, especially for weapons focused on timed or burst hits versus repeats of smaller damage attacks.  

Passive Abilities

The weapon’s passive ability initially increases Attack by 12% (which is indicative of  Level 1, 2, or 3) and can reach 24% at max syntonization (R5).  The unique part about Lux & Umbra is that its passive ability is dual trigger condition, using a Echo Skill Weapon gives a buff to Heavy Attack Damage for 6 seconds, using a Heavy Attack modifies the Echo Skill Damage by the same amount (24%-48%).  When you fully upgrade the weapon, instead of flat 24% buff it scales up to 48%.

When both buffs are active, the weapon will let the player completely ignore part of the enemy Defense. Starting at 8%, with R5 unlocked, this Defense Ignore goes up to 16%, allowing for significantly higher damage against tougher opponents. This occurs because the weapon encourages you to use echo skills and heavy attacks to keep both buffs active while significantly causing damage. 

Ascension Materials 

To fully ascend Lux & Umbra, players must farm some stuff from both the Phlogiston and Ring sets, and must also accumulate 330,000 Shell Credits. The total materials required include: 

  • Impure Phlogiston x6
  • Extracted Phlogiston x8
  • Refined Phlogiston x6
  • Flawless Phlogiston x20
  • Crude Ring x6
  • Basic Ring x6
  • Improved Ring x10
  • Tailored Ring x12 

Final Thoughts 

Lux & Umbra is a heavy hitter for characters who rely heavily on echo skills and heavy attacks. The weapon has reliable stats with passive abilities that work well together which makes it a solid weapon choice for Galbrena or characters who use pistols and want a balance between high consistent damage and high-burst damage. With the right rotation and timing, this weapon just works, and works well, across all types of encounters.
