The Damaged Bishop is a battered version of the normal Bishop which occurs naturally in the Ruins, but also has a chance of spawning from Broken Clockworks when they are destroyed. It has the same base stats as the standard bishop and drops 1 Purple Gem, with a chance of also dropping Nightmare Fuel and/or Thulecite Fragments.
The player can spawn an allied Damaged Bishop (or any other chess piece) by using 3 Gears to repair a pile of Broken Clockworks.
Damaged Bishop may be hostile towards other followers such as Chester, while remaining friendly towards player.
The Bishop usually stands close to the Wooden Thing, guarding it from any intruders. When any creature gets near its sight range, the Bishop will suddenly wake up and stare at them as a warning. Getting closer will make the Bishop attack by firing lightning bolts from its head. The Bishop will chase its enemy a short distance from its spawn area before returning and going back to sleep.
The Bishop is a moderately strong ranged mob, usually very accurate, so it is recommended to be armored and armed for a battle with one. Sending some Pigs to attack it first may prove to be an effective distraction. The player may try and use a Boomerang to kill it from far away, but this will grab the Bishop's attention, and it will start attacking. The player may also use an Ice Staff to freeze it, and then, start hitting it with a Spear, but it will cause some damage to the player. Another way to kill a Bishop would be to aggravate a nearby Clockwork Rook without waking the Bishop and get the Rook to ram the Bishop, as this will most likely kill the Bishop instantly (This strategy also works with Clockwork Knights and other mobs).
It is possible to dodge the Bishop's lighting bolts if the player is quick enough. Suddenly running to one side just as the Bishop is about to attack will usually leave the player unharmed by the lighting bolt, although the bolt does have a small area effect.
Another tactic to kill the Bishop is to lead all other mobs away, then use a Log Suit and Spear and hold down the attack button until it is dead, although this will cost the player a good amount of health, so it is only recommended to use this method when there is a decent amount of healing items in the player's immediate possession.
Below is the number of hits it takes with each weapon to kill Clockwork Bishops when playing with characters with a default damage modifier. The Weather Pain is not included due to the random nature of its projectile.
Clockwork Bishops (as well as knights and rooks) can be lit on fire with a torch. If on fire bishops and knights jump around until the flame extinguishes without attacking. While you will take fire damage from being close to them, you may take less damage than you would from tanking the bishop. Wormwood may be the worst at this strategy since he catches on fire easier and takes more damage from fire. Willow takes no damage from fire.
