The Rook will raise its front leg and slam on the ground several times before charging at and ramming the player. It will also destroy anything that stands in between it and the player, including other clockwork pieces. This is useful, as Clockwork Rooks will often kill other chess pieces in a couple of hits. Their attacks can be used to destroy structures as well, similar to Deerclops and Krampus. When the Rook hits a Tree, Boulder 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.
It is advisable to kill all Damaged Rooks in the vicinity of an Ancient Pseudoscience Station. The rooks can destroy even a perfect-condition Station in a single charge, resulting in the loss of a very rare resource. This will also summon the lightning strikes from the Station's destruction.
Below is the number of hits it takes with each weapon to kill Clockwork Rooks when playing with characters with a default damage modifier. The Weather Pain is not included due to the random nature of its projectile.
