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 does damage to the player on contact. Separate Spike Balls can have differing chain lengths. This, along with Blazing Wheel, are the only two enemies that don't take damage. 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 pre-hardmode dungeons or dungeons with a Brick Wall.

Tips

 * Placing a torch at the place where Spike Balls swing through the floor or walls will allow players to keep track of its path.
 * Pumpkins from The Horseman's Blade will follow Spike Ball.
