The Bubble Gun attacking Target Dummies. Notice how the bubbles pop when idle or when hitting a surface.

The Bubble Gun is a Hardmode magic weapon that rapidly fires a short-range spread of three bubble projectiles per shot. Bubble projectiles linger in midair and dissipate upon contact with an enemy or solid block. The Bubble Gun has a 20*1/5 (20%) chance of being dropped by Duke Fishron.

Its best modifier is Mythical.

Its best modifier is either Masterful for mana conservation or Godly/Demonic for higher damage output. It cannot get the Mythical modifier due to its low mana cost.



  • Its rate of fire, combined with its damage, gives it among the highest magic DPS in Terraria but at the cost of a very short range. Its effectiveness can be further enhanced by utilizing the Ichor debuff, e.g. using the Golden Shower.
  • The Bubble Gun has similar function to the Razorpine in single target DPS. The Bubble Gun gives significantly higher damage output and slightly more mana efficiency at the cost of range.
  • Because of its short range, spread, and lingering bubbles, it is most effective against large bosses that chase their target, like the Pumpking.
  • Because of its insane damage output, it is one of the best weapons against Plantera.


  • Desktop 1.4.4:
    • Projectile speed/distance increased from 11 to 15.
    • The bubbles now last twice as long before popping, meaning that more bubbles reach their full range, and they linger longer before disappearing.
    • Mana cost increased from 4 to 5, allowing access to better modifiers.
