The Liberty Cap is a trinket.

Effect

• Odd MushroomGrants an empty heart container. Increases damage, range and shot height while reducing speed.
• Odd Mushroom+1.7 tears, +0.3 speed, reduces damage.
• The CompassReveals all special rooms (except secret rooms of any kind).

Notes

• If the Compass effect triggers while having the Treasure MapReveals all rooms for every floor. However, it does not reveal icons or secret rooms., the Compass effect is permanent for the remainder of the floor. (Other Mushroom effects will still apply in each room with their normal odds.)
