Binding of Isaac: Rebirth Wiki

Curved Horn is an unlockable trinket.


  • Increases damage by 2, after normal calculations but before damage multipliers.


  • Normally, extra damage is reduced the more damage Isaac gets. Since Curved Horn is applied after every calculation, it will always be +2 damage.
  • Picking up Curved Horn while having damage multipliers, like Magic Mushroom Magic Mushroom or Cricket's Head Cricket's Head, makes Curved Horn even more beneficial from the multiplier (bringing, in the case of a x1.5 multiplier, the damage it grants to +3).
  • Curved Horn's damage does not ignore damage reduction multipliers, such as Odd Mushroom Odd Mushroom (damage * 0.9 - 0.38 damage down), Removed in RepentanceTechnology 2 Technology 2 (-35% damage down), and Soy Milk Soy Milk (-80% damage down).
