(in Repentance and Repentance+)

C Section is an unlockable passive item added in The Binding of Isaac: Repentance.

Effects

  • Isaac gains a short delay charge attack that fires homing, piercing, spectral fetus tears.
    • The fetus tears do 75% of Isaac's Damage, 3.75 times per second, until they run out of Range.
    • The fetuses will automatically fire when Isaac is at full charge, meaning the charge cannot be held.
    • Charge time is calculated based on Tear Delay.
      • Fetuses per Second=30Roundup(Tear Delay×3)+1
      • Fetuses per second is capped at 15.

Notes

  • Fetus size scales with damage.
  • The fetuses slow down upon contacting enemies, making its homing effect more powerful.

Synergies

    • This makes for a great synergy since the fetuses are homing and stay up much longer than regular tears.

Interactions

Other interactions:

Trivia

  • A Caesarean Section, or C Section for short, is a surgical procedure by which a baby is delivered through an incision in the mother's abdomen.
  • Isaac's body resembles a Vis.pngVis. The fetus shots themselves resemble Unborn.pngUnborns.
  • Prior to v1.7.5, this item had no effect other than changing Isaac's appearance and appeared in no item pools. Nonetheless, obtaining it was still required in order to unlock the Dead God Dead God Achievement.
    • It was only obtainable via Collectible Death Certificate icon.pngDeath Certificate and Collectible Spindown Dice icon.pngSpindown Dice, or as a starting item for Character Eden icon.pngEden / Character Tainted Eden icon.pngTainted Eden.
    • According to Edmund McMillen, C Section was a "dream item" whose mechanics and many hard-coded synergies were too complex to implement at Repentance's launch, with Kilburn "obsessively" working on the item and other parts of Repentance.[1]

Bugs

Bug Bug! There's no idle animation for C Section's costume, so Isaac (and every other character other than Character Lilith icon.pngLilith) will always appear to be walking when charging a shot, even when stationary.
Bug Bug! Character Tainted ??? icon.pngTainted ??? does not have a costume assigned for C Section (despite Character ??? (Character) icon.png??? having one), and nonetheless always appears to be walking while charging a shot, even when stationary (see previous bug).
Bug Bug! While Isaac has both C Section and Collectible Incubus icon.pngIncubus (including Character Lilith icon.pngLilith's inherent Incubus), Incubus' flying animation does not play while not firing; it floats around with no animation at all. The animation plays normally while firing.
