Loki's Horns is a passive item.

Effects

• Adds a chance to shoot tears in four cardinal directions, similar to Loki.

Notes

• The chance to shoot extra tears depends on the luck stat, and the formula used to determine the chance is: $\frac1 { 8 - \left \lfloor \mathit{Luck} \right \rfloor}$
  • At base luck (0), the chance is 12.5%, maxing out at 100% at 7 luck.
• The chance to shoot extra tears depends on the luck stat and is based on this formula: $25\% + (5\% * \mathit{Luck})$
  • This means that the chance starts at 25% at 0 luck, minimizes at 0% at -5 luck, and maximizes at 100% at 15 luck.

Synergies

• Mom's Eye: Each time Mom's Eye would activate, Loki's Horns activates instead. If Mom's Eye fails to activate, Loki's Horns' activation rate is still checked for afterwards.
• Eye of the Occult: Extra tears will fire in the same direction.
• Sprinkler: The sprinkler eye turns into four eyes and alternates shots between the cardinal and ordinal directions.
• Tiny Planet: Effectively grants a great tear multiplier, as on item activation the extra tears will follow the trajectory given by the Tiny Planet.

Interactions

• 20/20/The Inner Eye/Mutant Spider: No effect on the tears fired in the other 3 directions. The chance to activate is checked per shot, not for each tear fired.
• Dr. Fetus: Not recommended without immunity. Adds a chance to fire four bombs in cardinal directions.
• Epic Fetus: Adds a chance to spawn four crosshairs in cardinal directions. Isaac controls one and the others will mirror the movement keeping their space.
• Incubus: Not affected by Loki's Horns.
• Ipecac: Adds a chance to fire four explosive shots in cardinal directions. Caution is advised, though it is easier to avoid damage than Dr. Fetus.
• The Ludovico Technique: Adds a chance for 4 piercing + spectral tears to be fired in cardinal directions from the main tear. This chance scales with luck and goes up to 100% at 20 Luck.
• Mom's Knife: Adds four knifes on the cardinal directions around Isaac that can be rotated but all of them will be thrown when four tears would shoot with only Loki's Horns.
• Monstro's Lung: Only one red tear will be fired in the other directions.
  • Fires 14 tears in each of the four directions.
• Tech X: Overridden by Tech X.
  • The laser rings will only fire forwards and backwards, with 2 stacked on top of each other in both directions, shooting at an angle will shoot the stacked rings at different angles.
• Tractor Beam: Extra tears are not affected by Tractor Beam.

Trivia

• This item is used in Glass Cannon (challenge #11).
