Clockwork Rook

"A rook? Or is it a castle?"

- Wendy The Clockwork Castle is the 3rd monster in the Chess Monster collection. Like the Clockwork Knight and Bishop, the Castle is a mechanical creature generally found around Maxwell's parts of the world (Chess terrain and the Things). The Clockwork Castle is the combination of a rhino and a rook chess piece. When killed, it drops two Gears.

Behaviour
The Castle will raise its front leg and slam on the ground serveral times before charging the player. These large foes attack by ramming into the player. They will also destroy anything that stands in between it and the player, including other clockwork pieces. This is useful, as Clockwork Castles will often kill other Chess Pieces in one hit. Their attacks can be used to destroy structures, similar to Deerclops and Krampus. When the Castle hits a Tree or Beehive for example, it will quickly demolish it and leave the resources behind. This can be useful for helping to get Marble from Marble Trees without a Pickaxe.

Damaged Rook
Damaged rook looks like a galvanized rook.He has same base stats as clockwork castle and drops 2 Gears on death.

Trivia

 * The Clockwork Castle was implemented in the "Hungry For Your Hunger"  update.
 * The mob's design draws inspiration from the castle (or rook) in chess, which also can only charge ahead in straight lines.
 * When more than one Clockwork Castle are charging, they can collide in mid-charge and kill eachother.
 * A version called "Damaged Rook" will appear in the Ruins.  It can be spawned using DebugSpawn "rook_nightmare".  It also has a chance to spawn when hammering Broken Clockworks.
