Weapon Readjustment

You can use the Weapon Readjustment at the Weapon Workbench in Albion. Here are the best Weapon Readjustments for the Wave of Light:

Firearm ATK
Firearm Critical Hit Damage
Weak Point Damage
Weapon Change Speed

Try to upgrade the Weapon Readjustments to at least purple quality.

Weapon Cores

Weapon Cores juice up your damage quite tremendously. However, especially the later-level Weapon Cores are difficult to get. So start with whatever weapon cores you have available. Weapon Cores drop in the Void Erosion Purge endgame activity.

Higher level Weapon Cores drop in the higher level Void Erosion Purge levels in The First Descendant. However, you can gradually work towards the highest level. I recommend trying to get to level six as soon as possible, since it won’t require clearing many stages and will already increase the power of your weapon tremendously.

Best Weapon Cores for the Wave of Light:

Fire Rate (Free Augmentation)
Firearm ATK (Firepower Augmentation)
Fire Rate (Tactical Augmentation)
Weapon Change Speed (Precision Augmentation)
Flex (Special Augmentation)

Wave of Light Lore

While the majority of Albion’s Scout Rifles use 7.78 mm bullets, the “Wave of Light” employs special .300 Blackout bullets. The Blackout got its name from the flash of light that occurs when the firing pin strikes the detonator. Despite its high lethality, this flash made it impractical for night operations. The risk of being detected by the enemy was simply too high.

However, that drawback was mitigated when combined with the “Wave of Light,” as the weapon initially reacted with Arche, emitting light waves that were discovered to blind the enemy.
