Grants a chance of triggering one of the following effects for current room upon entering.


  • In Rebirth, it has a chance of dropping upon destroying mushrooms.
  • If the Compass effect triggers while having the Treasure Map, the Compass effect is permanent for the remainder of the floor. (Other Mushroom effects will still apply in each room with their normal odds.)


  • The pick-up quote is a reference to the Yoshi's Island level 1-7: "Touch Fuzzy Get Dizzy". 
  • Psilocybe semilanceata, commonly known as "Liberty Cap", is widely present in nature and is a very powerful psychedelic mushroom which contains psilocybin.
  • The Liberty Cap's ability to grant the Compass effect was a bug in the original Binding of Isaac which was carried over in Rebirth due to popularity with the fans.
