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 15►Magic Mushroom Magic Mushroom or 15►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 15►Odd Mushroom Odd Mushroom (damage * 0.9 - 0.4 damage down), Removed in Repentance15►Technology 2 Technology 2 (-35% damage down), and 15►Soy Milk Soy Milk (-80% damage down).
