Jump to navigation Jump to search

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: 110Luck[1]
    • At base luck (0), the chance is 10%, maxing out at 100% at 9 luck.

Interactions

  • (except in Rebirth and Afterbirth) Apple!Apple!: With 14 Luck, overrides Tough Love. With 13 Luck, Apple and Tough Love each have about an equal chance to trigger.
  • (in Rebirth) BrimstoneBrimstone: Overridden by Brimstone.
    • (except in Rebirth) Occasionally fires Brimstone beam with damage multiplier of Tough Love.

The frequency at which the tear very briefly transforms into a tooth increases with Luck, permanently becoming a tooth 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.
