Excava Summary

The First Descendant Excava Summary Unique Ability

Excava is a powerful composite rifle that gathers power generated by an electronic firing mechanism to fire voltage-accelerated energy grenades.

  • Name: Excava
  • Type: Assault Rifle
  • Bullets: General Rounds
  • Tier: Ultimate
  • Unique Ability: Voltage Accel Energy Grenade Launcher

Unique Ability “Voltage Accel Energy Grenade Launcher”

Hitting an enemy grants the unique effect Voltage Charge. When Voltage Charge reaches max stacks, it changes to the unique effect Energy Grenade. While Energy Grenade is active, fires an Energy Grenade when shooting while aiming, which deals increased damage based on the number of stacks. Hitting an enemy with the Energy Grenade inflicts Voltage Accumulation.

Modules are an important part of every weapon build in The First Descendant. For the Excava Assault Rifle we want to focus on Weak Point and Multi-Hit damage.

Weapon Readjustment

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

  • Multi-Hit Damage
  • Multi-Hit Chance
  • Weak Point 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 Excava weapon:

  • Free Augmentation Icon TFD Electric ATK (Free Augmentation)
  • Free Augmentation Icon TFD Electric ATK (Free Augmentation)
  • Attribute Augmentation Icon TFD Electric ATK (Attribute Augmentation)
  • Tactical Augmentation icon tfd Fire Rate (Tactical Augmentation)
  • Tactical Augmentation icon tfd Fire Rate (Tactical Augmentation)

If you play Gley, you can also do 4x Fire Rate or 3x Fire Rate because she has an infinite ammo skill.


Excava Lore

Excava Icon The First Descendant

The Excava composite rifle system is an infantry firearm with a unique electronic firing mechanism that uses high-voltage, electric current to fire rounds.

Furthermore, the voltage grenade launcher function, which accumulates power generated during the firing process to form massive energy, thereby accelerating it forward, is exclusive to the Excava system, as well as the its main attraction.

It is considered one of the most powerful personal firearms in Albion; capable of delivering complex attacks, yet is simple to operate.
