Phantom Arm Cannon demonstration.

The Phantom Arm Cannon is a craftable Hardmode Launcher. On use, it fires a spectre shot in the direction of the cursor. Holding the attack button will charge up the weapon; after 1.5 seconds, the following left-click will fire a slower but more powerful shot that creates an explosion on contact with a tile or enemy. Right-clicking will instead fire an accelerating phantom rocket towards the cursor before detonating. Only the detonation is able to damage enemies.

Its best modifier is Unreal.

  • While the left-click cannot autofire due to its charge, the right-click attack possesses the ability to autofire.
  • If the Show Donator Item Color configuration option is disabled, the Phantom Arm Cannon will have a rarity of Rarity Level: 8 instead of the standard Rarity level: Donator.
