E-Buster Summary

TFD E-Buster Weapon Ultimate Submachine Gun Stat Sheet

The E-Buster is an Ultimate Submachine Gun. A firearm designed to harness the increase in entropy caused by kinetic energy as usable energy. However, as that chaos cannot yet be fully understood, it is limited by highly inefficient energy conversion.

  • Name: E-Buster
  • Type: Submachine Gun
  • Tier: Ultimate
  • Unique Ability: Entropy Overload

E-Buster Build for The First Descendant

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

Here is all the info you need to build a powerful E-Buster:


E-Buster Modules

The First Descendant E-Buster Build

Modules are an important part of every weapon build in The First Descendant. For our E-Buster Build we are going to focus on Multi-Hit.


Weapon Readjustment

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

  • Electric ATK
  • Multi-Hit Chance
  • Multi-Hit Damage
  • Firearm ATK

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 to clear many stages and will already increase the power of your weapon tremendously.

Best Weapon Cores for the E-Buster:

  • Free Augmentation Icon TFDFirearm ATK (Free Augmentation)
  • Firepower Augmentation Icon TFDFirearm ATK (Firepower Augmentation)
  • Hit Augmentation Icon tfdMulti-Hit Damage (Hit Augmentation)
  • precision augmentation icon tfdSprint Speed or Grapple Hook (Precision Augmentation)
  • precision augmentation icon tfdSprint Speed or Grapple Hook (Precision Augmentation)

E-Buster Lore Info

E-Buster Weapon Icon TFD

Active research on the concept of entropy began following Nell’s awakening. Nell’s Arche ability, which directly manipulates Dimensional Breaches, their energy, and entropy itself, firmly established the previously abstract concept of entropy in many minds.

Even so, entropy and the degree of disorder remained convoluted concepts. However, as research progressed, many ideas emerged that directly utilized thermodynamic energy and entropy.

This firearm originated from one such idea, which involves converting the disorder inherent in electromagnetic forces of particles into kinetic energy. Although the energy loss during the conversion process was still significant, it demonstrated sufficient power for weaponization.

However, as it failed to materialize entropy into energy and merely incorporated an energy conversion technology, Nell commented:

“This isn’t true entropy. But the technical application is certainly commendable.”
