The Hellish Halberd is a Hardmode spear that has a chance to be dropped by Coznix, The Fallen Beholder. Upon successfully striking an enemy, the player will gain a charge. After obtaining 5 charges (indicated by burning embers emanating off of the player), the following use of the Hellish Halberd instead swings it like a broadsword, firing out a fiery vortex projectile.

The fiery vortex lasts for 5 seconds, deals 66.67% of the main weapon's damage, and can hit an unlimited number of times until it dissipates. The vortex automatically travels slowly towards the last enemy hit by the spear. The spear itself inflicts the Melting debuff for a short duration, but not the vortex.

Its best modifier is Godly.


  • The player can only gain 2 charges for the fiery vortex attack per spear swing, regardless if the thrust hits more than 2 enemies.
  • The weapon when firing the fiery vortex is a broadsword swing, and can activate sword-based effects such as Sword Sheaths.
