Blazing Wheel

The Blazing Wheel is an indestructible Enemy found in the Dungeon. It appears to be a ring of fire, traveling along the walls and floors of the Dungeon. Blazing Wheels move quicker than most Dungeon enemies and produce light. They appear in areas that have a Dungeon Brick Wall background.
== Movement ==
* They spawn and despawn off-screen, like any other enemy.
* They will go through open doors, but not through closed ones.
* They travel through Platforms, not along them.
* If you remove all of the blocks the Blazing Wheel is spinning on, it will fly towards a random 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.
* They move at a surprisingly fast speed, making it harder to dodge them.
== Notes ==
* The Blazing Wheel can hurt NPCs, including the Mechanic who spawns in the Dungeon.
* Though Blazing Wheels appear to be ablaze themselves, they do not inflict the On Fire! debuff.
* Blazing Wheels do less damage than Spikes.
* Despite their unusual properties, Blazing Wheels can actually be moved by Teleporters.
* Blazing Wheels show up on the Radar since they are technically enemies.
* The Blazing Wheel AI is nearly identical to the Snail AI.
== 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.
* To avoid the Blazing Wheel's attack, look for its light in dark areas, move as far away as possible, then jump or avoid it if you don't want to lose health.
== Trivia ==
* The Blazing Wheel, along with the Spike Ball, the True Eye of Cthulhu, and Golem Head in his second stage are the only four invincible enemies in Terraria.
* Although the Blazing Wheel cannot be damaged, it has most of the statistics of a normal enemy, including a death sound, a hit sound, defense, and immunities to a few debuffs.
* The Blazing Wheel is likely based off the Hothead from the Mario franchise. It moves in similar motions when climbing on walls and ceilings and is also based around a fire theme.
** Though, they more closely resemble Rinkas from Metroid.
