The Cellar is a variant of the first and starting Floor in The Binding of Isaac: Rebirth. It has two stages (The Cellar I and The Cellar II) and is unlocked by defeating all of The Basement's Bosses (except Steven).

Unique Features

  • Jars are found in The Cellar. They will either contain nothing, Spiders, Coins, The Swallowed Penny, or The Quarter upon being exploded, the chances of said items spawning being in order from greatest to least.
  • The Item Room requires no Key to open.
    • If Curse of the Labyrinth (XL Floor) is in effect, both Item Rooms will require no Keys.
  • The Cellar's theme is Spiders.
