The Binding of Isaac Wiki

The Tick is a trinket added in the Wrath of the Lamb DLC.

It is a small-sized brown tick.


  • Removes 15% of any enemy's HP if they have over 60% HP.
  • Gives Isaac one red heart if he enters an uncleared boss room.
    • This effect can allow Isaac to infinitely gain HP, if he has access to any infinitely usable teleportation effect (such as Teleport!).
  • Once picked up, it cannot be removed (as of v1.48).
  • Mom's Purse also allows Isaac to pick up an additional trinket alongside The Tick.
