Little Horn (Item)

This article is about the item. For the boss, see Little Horn.

Little Horn is a passive item added in The Binding of Isaac: Afterbirth †.

Effects[]

Adds a chance to fire piercing tears which will instantly kill any non-boss enemy.
Adds a chance to fire a tear that summons Big Horn's hand. It will grab and crush any non-boss enemy, killing them instantly, and attacks bosses 3 times for 12 damage each hit (even Big Horn himself).
- Big Horn's hand is able to push projectiles of enemies away from the source of contact. These tears gain additional speed. This makes it especially difficult for the player to dodge while fighting Hush, as it fires a lot of tears and many are propelled by a turning force.
Running into enemies deals 3.5 damage to them.
- Damage is dealt up to twice per second per enemy.

The chance to fire special tears depends on the luck stat, and the formula used to determine the chance is: $min(\frac1 { 20 - \left \lfloor \mathit{Luck} \right \rfloor}, 20\%)$ $min({\frac {1}{20-\left\lfloor {\mathit {Luck}}\right\rfloor }},20\%)$
- At base luck (0), the chance is 5%, maxing out at 20% at 15 luck.
The special tears will kill some normally invulnerable monsters, such as Death's Heads, Stoney, and Peep's floating eyeballs.
The special tears can also destroy Blue Fire Places and Purple Fire Places.
The special tears can destroy the various spiked blocks ( Wall Hugger, Slide, and Poky) as well as the variants of Stone Grimace. All of these won't respawn if Isaac leaves and re-enters the room.
The contact damage effect overrides the superior contact damage from Aries, The Gamekid, My Little Unicorn / VII - The Chariot, and The Nail. Only Midas' Touch still works and deals an additional 3.5 damage.
- The contact damage adds to other contact damage sources.

Angelic Prism: Little Horn tears can be split by the prism and will be quadrupled when they pass through it.
Brimstone/Mom's Knife: Each damage tick may trigger Little Horn's effect.
Evil Eye: Eyes can fire Little Horn tears. Little Horn tears won't destroy other eyes.
Jacob's Ladder: Enemies hit by Jacob's Ladder's arcs produced by a Little Horn tear will be hit by Big Horn's hand.
Kidney Stone: The stone can have the Little Horn effect.
Soy Milk: Due to its high tear rate, the effect will trigger very often, even with average luck stats.
Saturnus: Little Horn tears can orbit around Isaac upon entering a room.
Tech.5/Technology/Tech X: Occasionally fires a Little Horn laser beam.
Technology 2: The laser can also trigger Little Horn’s effect with the laser’s chance to apply the effect being determined rapidly every tick.

Brimstone/Mom's Knife/Technology/Tech X: Overrides Little Horn’s tear effects.
Dr. Fetus / Epic Fetus: Overrides Little Horn’s tear effects.
- Black-tinted bombs can summon Big Horn's hand to instantly kill non-boss enemies or to deal damage against bosses.
Lachryphagy: If Little Horn tears are fed, they will burst into split tears with the same effect. If Little Horn tears feed normal tears, however, the effect is lost.
Tech.5/Technology 2: The laser is unaffected by Little Horn.
Technology Zero: Electricity connected to Little Horn tears will not instantly kill enemies.
