A glass crystal ball, with Isaac's reflection looking into its interior and a purple frame holding the ball.

Effects

Upon activation, the map of the current floor will be revealed, (unless the Curse of Darkness is enabled), and a Tarot Card or Soul Heart will drop with equal chance.

Trivia

  • It is possible to already have a Crystal Ball while finding another one in a fortune telling machine. In this case, the charge levels of both balls will be the same.
