Little Horn is a boss added in The Binding of Isaac: Afterbirth that can appear in all environments of Chapter 1 (BasementBasement, CellarCellar, Burning BasementBurning Basement).

Behavior[ | ]

Little Horn constantly tries to evade Isaac by moving away from him while performing the following attacks:

  • Creates and jumps into a PitfallPitfall and pops up elsewhere.
  • Creates 3 to 5 Teleport PitfallTeleport Pitfalls that move outwards.
  • Creates a regular Pitfall under himself that lasts for several seconds.
  • Throws a Troll BombTroll Bomb or a Mega Troll BombMega Troll Bomb into a created Pitfall underneath himself. The bomb then pops up near Isaac's position.
  • Jumps into a Pitfall and appears elsewhere while leaving a Troll Bomb in his place; repeats this process 3-5 times.
  • Spawns a Dark BallDark Ball.

(in Repentance) Little Horn takes reduced damage (25 instead of 100) from his own bombs. Bombs from other sources still do full damage.

Champion Versions Needs to be unlocked[ | ]

(in Afterbirth † and Repentance) Black: Does not attack with Pits, Troll Bombs or Mega Troll Bombs, but fires Dark Balls more frequently. This version can still do the chain teleport attack but doesn't spawn any Troll Bombs.
(in Afterbirth † and Repentance) Orange: Spits out an orange Troll Bomb instead of a Dark Ball. This Troll Bomb deals contact damage and leaves a patch of fire similar to Collectible Hot Bombs iconHot Bombs that cannot damage him. He also throws these special Troll Bombs into Pitfalls instead of normal ones, and spawns them during the chain teleport attack. He loses 1 HP whenever he spits out a bomb. Does not attack with Mega Troll Bombs.

Notes[ | ]

  • The Collectible Gnawed Leaf iconGnawed Leaf can make the battle easier, as Little Horn will damage himself with his bombs over time. Isaac can still fall into the pits and be transported around the screen, and will appear to suffer damage, but no actual loss of HP will occur if he is in statue form when he falls in.
  • The Dark Balls that Little Horn spawns can appear in Closets in the CavesCaves and the Flooded CavesFlooded Caves. They also appear in a room with Little Horn in the ChestChest.
  • If Isaac has the Safety ScissorsSafety Scissors, he can acquire maximum bombs from the fight at fairly little risk since the bombs Little Horn spawns will turn into bomb pickups and all his hole attacks are easy to dodge.
  • Little Horn's Dark Ball is considered a monster. Killing it will activate items such as Collectible Charm of the Vampire iconCharm of the Vampire, Collectible Infestation 2 iconInfestation 2, and Collectible Jar of Flies iconJar of Flies.
  • Occasionally, a Pitfall that Little Horn summons will not vanish after defeating the boss. The Pitfall is still active and can damage Isaac, even if it does not actively chase the player.
