Brainstormer Borderlands 3 Legendary Showcase

About the Brainstormer:

The Brainstormer is a Legendary Weapon in Borderlands 3. This Hyperion Shotgun always has the shock element. It fires multiple projectiles in a lightning bolt pattern. The Brainstormer is great for mobbing and stripping shields. This is because of its legendary effect as it can create a chain lightning shock between enemies that are in close proximity to each other. There are always 2 lighting beams when a link is made, 1 from your original target to another, and then a second one can go it back to the original target or attach to another target. This link will last 2 seconds and deal 10 ticks of damage during that time and each target can have up to 5 links.


  • Always Shock
  • Check out the Reflux if you want a Corrosive variant

Special Weapon Effect:

“Let’s put our heads together.”

  • Fires 7 or 14 projectiles in a lightning bolt pattern.
  • Hitting an enemy has a chance to cause powerful shock bolts chaining from the target hit to nearby enemies.

How to get the Brainstormer?:

The Brainstormer can be randomly obtained from any loot source but it has a high chance of dropping from Katagawa Ball who is located in Skywell-27 on Promethea. It’s the boss at the end of the Space-Laser Tag story mission.

Drop Rate:

The Drop Rate of the Brainstormer is 13.5% on Mayhem 6+; 30% Otherwise


  • Although the bolts’ way of dealing damage may look similar to a Status effect, only gun damage modifiers are applied, not status effect modifiers. Thus, Amara’s Anima skill cannot increase the duration of this effect.
  • A Brainstormer with the Redundant prefix (fires 14 pellets and consumes 2 ammo per shot) has an increased chance of causing more bolts. However, a cash infused Brainstromer with a bonus element creates about the same number of chains as a Redundant.
  • Bonus elemental damage from shields, grenade mods, or skills like Amara’s Infusion and Forceful Expression, also increase the chance of causing more bolts.
  • If no enemies are nearby, no shock bolts will occur, greatly reducing the effectiveness of the weapon.
  • The Brainstormer and its chains are entirely unaffected by splash and AoE boosts.
  • This weapon synergizes well with FL4K’s Megavore skill and the  The Pearl of Ineffable Knowledge.
  • The Brainstormer occasionally appears in Maurice’s Black Market.



  • The term “let’s put our heads together” is a term to pool ideas and work together. The name of the gun furthers this as to brainstorm is to come up with new ideas.
  • The spread of the pellets is shaped like a lightning symbol
