Weapon Readjustment

Thunder Cage Weapon Readjustment Options TFD

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

  • Firearm ATK
  • Elemental Damage
  • Critical Hit Damage
  • Rounds Per Magazine (or Critical Hit Rate)

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 Thunder Cage:

  • Free Augmentation Icon TFDChill Damage (Free Augmentation)
  • Firepower Augmentation Icon TFDFirearm ATK (Firepower Augmentation)
  • Hit Augmentation Icon tfdFirearm Critical Hit Damage (Hit Augmentation)

Thunder Cage Budget Build Setup

Thunder Cage Budget Setup TFD

Here is a budget setup for the Thunder Cage, because it is the first good weapon you likely have access to but you won’t be able to fully module spec it. Here is a guide on how to get Thunder Cage in The First Descendant.

  1. Energy Activator: This setup requires an Energy Activator to increase the Module Capacity from 50 to 80. You should have one or two from the main storyline. We also have an in-depth guide on how to farm Energy Activators in The First Descendant.
  2. Module Aquisition: Open the Map, then navigate to the “Library” (one tab to the left), now click on Module. Search your Module and press “Acquisition Info” to see where it drops. You want to white bullet icon Modules, because Thunder Cage uses General Rounds.
  3. Slot 3 and Slot 6 are already crystallized slots, you get the gun like this. So make sure to place the exact same Modules in these slots to reduce the cost of the Module. Otherwise not all Modules will fit!

Thunder Cage Lore Info

TFD Thunder cage Weapon

The “Thunder Cage” is hailed as the most successful attempt at electrifying a technology used by the Ancestors. It is a combination of the prototype of Bunny’s suit technology and a submachine gun.

This firearm, considered Albion’s strategic weapon for the next generation, converts kinetic energy into electromagnetic force, which is stored in a specialized battery. Once the energy reaches its critical state, the user can use a Sub Attack which releases the energy in one powerful burst. The power of this sub attack influenced the weapon’s official name. The Magisters said it looked like trapped thunder being released, leading to the weapon being called the “Thunder Cage”.

Keep in mind that as the firearm’s internal devices function independently from Bunny’s Arche ability, there is no additional effect when used by Bunny.
