The Ball o' Fugu auto-firing against a Target Dummy, and releasing thorns during travel which home in on a nearby Super Dummy.

The Ball O' Fugu is a Pre-Hardmode flail obtained from Shadow Chests in the Abyss. It throws out a pufferfish, which behaves similarly to the Flairon, dispersing homing urchin spikes into its vicinity.

Like the Flairon, it closely resembles a thrown flail. However, it functions more closely similar to items like Chain Knife and Golem Fist. It is not affected by gravity, does not remain deployed when holding the fire button, and cannot be swung around. Rather, holding the fire button causes it to auto-fire repeatedly, returning and re-firing when it impacts or reaches its maximum range.

Its best modifier is Godly. It cannot get modifiers that affect size.


Used in


  • Because the weapon fires thorns while it is out, it can often be beneficial to miss targets to maximize damage output.
  • The Ball O' Fugu can be considered the indirect upgrade to the Urchin Flail.
  • This weapon can also be obtained from the Abyssal Crate after either The Slime God or Wall of Flesh have been defeated.


  • In real life, Fugus are pufferfish that are eaten as a Japanese delicacy, after some highly poisonous parts have been removed.
