Binding of Isaac: Rebirth Wiki

My Little Unicorn is an activated item.


  • Gives invulnerability and +0.28 speed for six seconds, removing the ability to shoot tears and replacing it with the ability to deal contact damage to enemies.
    • Removed in Repentance Isaac deals 40 contact damage to enemies, once per second.
      • Added in Repentance Isaac deals 20 contact damage to enemies, twice per second.


  • The invulnerability effect negates all forms of damage, including health loss from Blood Donation Machine.png Blood Donation Machines and Devil Beggar.png Devil Beggars.
  • Does not prevent Heart Container loss from Health Down pills or Devil Deals.
  • Ending the current run via opening the end chest while My Little Unicorn is active will cause the credits and main menu music to be sped up. The effect ends upon restarting the game or starting a new run.
  • VII - The Chariot VII - The Chariot card provides the same effect of this item when used.


  • Added in RepentanceBook of Virtues Book of Virtues: Spawns rainbow-colored wisps in the middle ring. The wisps orbit Isaac more quickly than normal wisps and change colors constantly, with both of these effects being boosted while My Little Unicorn is active. The wisps also deal an extra 8 contact damage, for a total of 15 contact damage per tick. When de-activated, the rainbow coloring slightly fades away.
