Montezuma's Revenge

Montezuma's Revenge is a passive item added in The Binding of Isaac: Repentance.

Effects

 * Continuously shooting for 2.35 seconds allows Isaac to fire a short-range poop laser and corn shots behind himself by releasing the fire button, similar to the laser created by, but more akin to 's.
 * The laser deals Isaac's damage per tick (15x Isaac's damage per second), hitting 19 times in one charge, and lasts ~1.28 seconds (77 frames).
 * Corn shots deal 6 damage, and a random amount are created each blast.

Synergies

 * Brain Worm: Can cause the poop laser to hook to a target anywhere in the room, potentially hitting a target far outside of its usual range.
 * : The corn Isaac poops out can be sliced, giving Isaac an insane damage up in seconds.
 * : The poop beam will unleash a barrage of explosions at the end of it.
 * : Spawns a large amount of tears at the end of the poop beam, heavily increasing Isaac's damage output.
 * : Beam splits into two horizontal beams meaning less risk for Isaac and a bigger area for enemies to be hit.
 * : Causes the beam range behind Isaac to become significantly increased as well as having a short range similar to Azazel's beam in front of him. This greatly eases the use of this item allowing for high DPS.

Trivia

 * Montezuma's Revenge is a colloquial term for Traveler's Diarrhea, an intestinal infection caused by ingesting contaminated food or water. Montezuma II was the last Aztec ruler before the Spanish conquest of the Aztec civilization, and the sickness is seen as a curse afflicting tourists visiting Mexico as revenge for the Aztec massacre.
