Binding of Isaac: Rebirth Wiki

Tough Love is a passive item.

Effects[ | ]

  • Adds a chance to shoot a tooth instead of a tear, which deals x3.2 Isaac's damage.

Notes[ | ]

  • The chance to fire a tooth depends on the luck stat, and the formula used to determine the chance is: [1]
    • At base luck (0), the chance is 10%, maxing out at 100% at 9 luck.

Trivia[ | ]

The x3.2 damage multiplier is likely a reference to the fact that full set of adult teeth amounts to 32 teeth in total.
