Bishop

Bishops are stationary enemies added in The Binding of Isaac: Repentance. They appear only in and.

While a Bishop is alive in the current room, all other enemies that aren't Bishops will be given shields, protecting them from all damage taken; all Bishops in the room must be killed for the other enemies to take damage as normal. Additionally, when Bishops take damage, they retaliate by firing shots in the cardinal directions.

Trivia

 * In Antibirth, Bishop's robes had a purple color, and they didn't shoot tears after taking damage.
