How to Unlock The Lost in Binding of Isaac – Afterbirth

Step by step to unlock The Lost in Binding of Isaac Afterbirth:

1. Looking for Mom’s Box in shops makes finding the poster easier.
2. Glitter Bombs, in conjunction with a large enough or infinite source of bombs (such as a Gold Bomb), have a small chance to drop trinkets, making it easier to find the poster.
3. It is technically possible to unlock The Lost while holding  Mysterious Paper, although the probability is small since it only has a 1/4 chance to imitate the  Missing Poster. Dead Cat and other resurrection items could be useful for extra attempts.

1. Isaac must die to a Mulliboom in The Basement or The Cellar.
2. Magdalene must die to her own bomb in The Caves or The Catacombs.
3. Judas must die to any Mom attack in The Depths or Necropolis. Being killed by any monster spawned by Mom will spoil the entire attempt at unlocking The Lost.
