Blazing Wheel

The Blazing Wheel is an indestructible enemy found in the Dungeon. It resembles a firey circular saw blade, traveling along the walls and floors of the Dungeon. Blazing Wheels move quicker than most Dungeon enemies and produce light. They appear first in pre-Plantera Dungeons, and in Hardmode Dungeon areas that have a Tiled Wall background.

Movement

 * They spawn and despawn off-screen, like any other enemy.
 * They will go through open doors, but not through closed doors.
 * They travel through Platforms, not along them.
 * If you remove all of the blocks the Blazing Wheel is spinning on, it will fly towards the nearest wall.
 * If you surround a Blazing Wheel with blocks until there are only 2-3 tiles of space for it to maneuver, it will despawn.
 * Blazing Wheels will go outside of the Dungeon, however it is very rare, and you must follow it until it does.

Tips

 * A useful way to avoid being hit by the Blazing Wheel is to use a Multi Hook to suspend yourself in midair, rather than standing still on a Dungeon surface.
