Blazing Wheel

The Blazing Wheel is an indestructible enemy found in the Dungeon that looks like a circular saw on fire. The Blazing Wheel glides along the walls and floors of the dungeon. They produce light and move quicker than many enemies. This, along with Spike Ball, are the only two enemies that don't take damage (with two exceptions listed below). They spawn and despawn off-screen like any other enemy and only appear in pre-hardmode dungeon and hardmode dungeons with a Tiled Wall.

Tips

 * The Blazing Wheel will go through open doors, but not through closed doors. This can be used to trap it, or to simply alter its path.
 * The Blazing Wheel travels through Wood Platforms, not along them.
 * When you remove all of the blocks the Blazing Wheel is spinning on, it will fly towards the nearest wall.
 * A useful way to avoid being hit by the Blazing wheel is to have a Ivy Whip, and use that to avoid its path in midair.
