Type Cursed Cannonball

The Helmball is a resource item that is used as specialized Cannon ammunition that curses an opposing ship's Helm, restricting its use for a short time.

Where to find[]

Helmballs have a low chance to appear in Barrels all over the world. Helmballs can also be unloaded from Cannons that have been loaded with a Helmball. Some Skeleton Ships use Helmballs as a part of their arsenal.


Helmballs are mainly used as ammunition for loading up and shooting with Cannons. A Helmball needs to be loaded inside an empty Cannon before it can be used as ammunition. Once a Cannon is loaded, the player can manually aim the Cannon with Directional keys and then Shoot the Helmball with the Primary Use key. As the fired Cannonball's firing trajectory and arc is influenced by the angle of the Cannon and the sailing speed of the Ship, hitting targets with Cannonballs requires some practice.

Helmballs are used to Curse Ships or Skeleton Ships by locking their Wheel in place. The Wheel will be affected for a few seconds, making it impossible to turn the ship during the effect. The effect itself is shown by the Wheel getting covered in purple smoke. Skeleton Ships will sail straight once hit by a Helmball. Note that Helmballs do not do direct damage to a Ship or Enemies, therefore being useless against live targets.


  • Up to 10 total Helmballs can be held in a player's inventory at one time.
  • A single Helmball can be loaded into any Cannon, signified by a fuse appearing on front of the Cannon and purple coloured smoke appearing from its muzzle.
  • Up to 100 Helmballs can be stored in one storage space of a Barrel at a time. A single Ship's Cannonball Barrel can carry up to 3 pages worth (i.e. 4800) of Helmballs.
  • Up to 20 Helmballs can be stored in one storage space of the Rowboat Chest. A single Rowboat's Chest can carry a maximum of 2 pages worth (i.e. 640) of Helmballs.

In-Game Description[]
