When He broke the second seal, I heard the second living creature saying, “Come.” And another, a red horse, went out; and to him who sat on it, it was granted to take peace from the earth, and that men would slay one another; and a great sword was given to him.
— Revelation 6:3-4˄ NASB

War is an enemy in The Binding of Isaac: Rebirth. It appears as a Boss on The Depths and the Necropolis Floors as well as a Monster on later Floors.


War has two phases which are as follows:

  1. War will float around the room, occasionally charging across the screen 3 times. It will also randomly fly into the air, spawning 5 Troll Bombs and charge back into the Room once they have detonated. It can also randomly shoot 8 tears in an asterisk pattern.
  2. At half health, War will lose its horse, quickly chasing the player and occasionally pausing to catch its breath.

Champion Variants

War has one Champion variant.

  • War will be black and, instead of spawning 5 Troll Bombs, War will spawn 2 Super Troll Bombs. It will also shoot 6 tears in an asterisk pattern while catching its breath.
