"He wants revenge"

  • Spawns a familiar that follows Isaac.
  • After entering a boss room, the familiar will move closer to the center of the room, and become a clone of the boss. Isaac must defeat both bosses.
  • The Vanishing Twin and original boss will be set to 75% of their maximum health, and their attack patterns will be slightly slowed.
  • Upon death, the clone boss will drop an item pedestal from the boss item pool, even if the fight isn't over yet.
  • The effect doesn't occur against end-chapter bosses such as Mom, Mom's Heart, Isaac (Boss) etc.
  • The Vanishing Twin familiar will return when Isaac reaches the next floor.
