Closet

A closet is a rare, small, dead-end room added in The Binding of Isaac: Afterbirth. Closets often contain a unique arrangement of objects, pickups, items, or enemies, but are otherwise identical in appearance to normal rooms. Each chapter has several closet layouts, some differing between stages themselves. Some closets are considerably more rare than others, but also often contain more powerful loot or enemies.

A normal small corridor can also generate in a dead-end location or have a secret room at its other end, appearing like a closet, but these are not covered in this article.
