  • Any touch-based attacks or status effects such as Aries Aries or The Virus The Virus: Freely usable in every room.
  • Any orbital-like item (Cube of Meat Cube of Meat, Sacrificial Dagger Sacrificial Dagger): The orbital can be used freely in every single room, making it a great alternative source of damage.
  • Mom's Knife Mom's Knife does contact damage in the same direction it was being held at the time of using the Unicorn Stump, giving a massive amount of free damage by ramming into an enemy.


  • Added in RepentanceBook of Virtues Book of Virtues: Spawns an orbital rainbow Wisp on each use of Unicorn Stump, giving up to 8 extra orbitals. Wisps do not deal contact damage.
