Wavy Cap is an activated item added in The Binding of Isaac: Repentance.

Effects[edit | edit source]

  • Gives Isaac a flat +0.75 fire rate even past the normal cap, -0.03 speed and distorts the screen and background music. The effects can be stacked in the same room, and the distortion becomes more pronounced with repeated use.
    • Each use increases the recharge time, with the 9th use having a recharge time of 15 seconds. After the 10th use, it no longer recharges automatically though it can be recharged and used even more through batteries.
    • Leaving the room doubles the speed penalty and multiplies the fire rate bonus by x0.4, for the uses in that room.
    • Clearing a room removes one use's worth of penalties and bonuses, giving +0.06 speed and -0.3 fire rate.
    • Isaac's costume will change the stronger the Item's effects get.
  • This item belongs to the Fun Guy set. Collecting three items from this set will transform Isaac into a walking mushroom.

In-game Footage[edit | edit source]

Trivia[edit | edit source]

  • Since the fire rate increase is flat, it is technically possible to reach 120.0 with enough uses. In practice this will likely render the game unplayable due to distortion.
  • This item originated from Antibirth and was called Black Mushroom.
