Binding of Isaac: Rebirth Wiki

Epic Fetus is an unlockable passive item.

Effects[]

  • Isaac's tears are replaced with guided missiles. Pressing the fire buttons spawns a crosshair that can be moved freely, summoning a missile to its position from above 1.5 seconds later.
    • Missiles deal 20 times Isaac's damage.

Notes[]

  • Removed in Repentance Epic Fetus is a special item.
  • Removed in Repentance Epic Fetus overrides most items in the game and has the highest priority of all tear modifiers, over 15►Brimstone Brimstone and 15►Mom's Knife Mom's Knife.
  • Isaac's tear delay determines how quickly a new (set of) missile(s) can be fired after the previous one has landed. Barring very high tear delay, this has little effect on damage rate due to the delay of the missiles themselves.
  • Missiles benefit from some bomb modifier items, though at a lesser scale compared to 15►Dr. Fetus Dr. Fetus.
  • Stacking multiple copies of the item causes a barrage of missiles in quick succession without resetting the crosshair's position, up to sixteen at a time.

  • 15►Blood Clot Blood Clot/15►Chemical Peel Chemical Peel: Each missile has a 50% chance to deal 20 or 40 points more damage, respectively.

Trivia[]

  • In the original game it was possible to control the crosshair with the mouse. This was removed in Rebirth.
    • Mouse control can however be re-enabled by editing the options.ini file in C:\Users\<username>\Documents\My Games\Binding of Isaac Afterbirth/Rebirth and changing the line MouseControl=0 into MouseControl=1. Also useful for The Ludovico Technique.
  • The Dr. Fetus and Epic Fetus items are based off of Dr. Fetus, the main villain in Super Meat Boy which is a game by Edmund McMillen (the creator of The Binding of Isaac: Rebirth).
  • In Wrath of the Lamb, Epic Fetus could be found in both the Secret Room and Treasure Room item pools.
    • Added in RepentanceEpic Fetus was added to the Secret Room item pool.
  • This item is used in Glass Cannon (challenge #11).
