Spike Ball

The Spike Ball is an indestructible enemy found in the Dungeon that swings around in a circle from a central pivot point (which also cannot be destroyed), and deals damage to the player on contact. Separate Spike Balls can have differing chain lengths. This, along with Blazing Wheel and the True Eye of Cthulhu, are the only three enemies that don't take damage, and are therefore invincible. They spawn and despawn off-screen like any other enemy &mdash; if you leave a room and return later, it will have a different configuration of Spike Balls. They only appear in dungeon areas with a Brick Wall.

Tips

 * Placing a torch at the place where a Spike Ball swings through the floor or walls will allow players to keep track of its path.
 * Spike Balls only spawn in areas marked by the Marching Bones Banner.
 * The Mechanic (after rescue) and other NPCs will attack Spike Balls.
 * Pumpkins from The Horseman's Blade will follow Spike Balls.
 * The Leaf Crystal that hovers above the player when wearing Chlorophyte armor fires at Spike Balls.
