The Helstorm is a craftable Hardmode gun. When used, it rapidly auto-fires two bullets at once, with a slightly random spread. The gun itself deals contact damage to enemies, a unique property for a ranged weapon that it shares with the Hellborn. Enemies that take contact damage from the gun will be inflicted with the Hellfire debuff.

Its best modifier is Unreal.

  • As the gun's hitbox does not change based on aim, it will not always hit enemies that pass through the sprite.
  • When dealing contact damage with the gun itself, the base damage is the same and the damage type is still Ranged.


  • Despite being called the "Helstorm", it does not share a connection with The Underworld.
    • This is likely because Scoria Ore used to spawn in the Underworld, before being moved to the Abyss.


These history sections are still a work-in-progress, and may not yet contain changes relevant to the current version of the Calamity Mod.
    • Now inflicts Hellfire instead of On Fire!.
    • Decreased sell price from 16 Gold Coin to 12 Gold Coin.
  • No longer considered a fire weapon.
