Blighted Ovum is a boss that can appear in Cellar Cellar.

Behavior[]

Blighted Ovum starts separated into two parts.

  • Suture is invincible and slowly floats towards Isaac, firing a horizontal 15►Brimstone Brimstone shot whenever Isaac is to its left or right. Suture can not be killed and will die once Contusion does.
  • Contusion constantly chases Isaac while leaving behind a trail of red creep, he periodically charges and gains speed. Unlike Gemini, he will not stop for a breath but slows down to his regular speed.
