Weapon Readjustment

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

Firearm ATK
Multi-Hit Damage
Weak Point Damage
Firearm Critical Hit Damage

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 Piercing Light:

Chill ATK (Free Augmentation)
Chill ATK (Attribute Augmentation)
Reload Time Modifier (Tactical Augmentation)
Weapon Change Speed (Precision Augmentation)
Aimed Shot Accuracy(Precision Augmentation)

Piercing Light Sniper Rifle Lore

A chief consideration when developing a weapon to use with this new technology, called “Dispel”, was how accurately it could hit its target. In this regard, it was only a matter time that the sniper rifle used by the most skilled marksmen would be selected for the job.

In order to properly use the “Dispel” skill, “Piercing Light” uses special ammunition that can store energy internally. Called a Hollow Round, this bullet contains a special empty space to store energy inside a battery.

The energy created within the Dispel device that’s built-in to the firearm gets stored in this bullet and ultimately strikes the enemy. An enemy hit by this bullet will have their buffs neutralized and eliminated.
