Next, let us take a look at an optimized Exterminator Build for The First Descendant.

Here is all the info you need to create a powerful Exterminator Build:

• Modules
• Weapon Readjustment
• Weapon Cores

Note: High-Level Weapon Cores boost your weapons’ damage numbers into insanity. Make sure to get weapon cores as soon as possible!

Exterminator Modules

Modules are an important part of every weapon build in The First Descendant. For the Exterminator Rocket Launcher, we want to focus on critical and explosion radius.

• Elemental Damage: Adjust the elemental modules depending on what enemies you fight (Enemy elemental weakness).

Exterminator Module Configuration Table

Module Slot	Module Name	Socket Type
1	Rifling Reinforcement	Malachite
2	Fire Enhancement	Almandine

Weapon Readjustment

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

• Firearm ATK
• Firearm Critical Hit Rate
• Firearm Critical Hit Damage
• Elemental 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 Exterminator:

• Fire Rate (Free Augmentation)
• Chill ATK (Attribute Augmentation)
• Chill ATK (Attribute Augmentation)
• Fire Rate (Tactical Augmentation)
• Fire Rate (Tactical Augmentation)

You want to go as much Fire Rate as possible, hence 3x Fire Rate and 2x Elemental ATK.

Exterminator Lore

As the battle raged on the Axion Plains, Albion Headquarters encountered a major problem, the presence of Spikers armed with hardened shells and troop-carrying Vulgus Special Assault Ships.

Unable to effectively counter them with conventional firearms, they were forced to rely on the Arche abilities of a few Descendants or on specialized weaponry to deal with them quickly. The Exterminator was developed to end such concerns, taking the base design of the Vestigial Organ and equipping it with a special chip, capable of high-performance and real-time calculations, to implement a system that can acquire the most valuable targets and guide the shells to them in real time.

With an increased overall size for greater firepower than the Vestigial Organ and a modified capacity to hold more ammunition, this Launcher became heavier than originally anticipated, but no other weapon is more efficient in its original purpose of destroying armor.

HQ is looking forward to this new weapon living up to its name, the Exterminator.
