Guillotine is an unlockable passive item.

Effects[]

  • Isaac's head becomes an orbital familiar that blocks shots and deals contact damage. Tears are still fired from the rotating head.
  • +1 damage.
  • (except in Repentance) -1 tear delay (increased rate of fire)
    • Since this directly affects tear delay instead of changing the tears stat, it allows Isaac's rate of fire to go over the normal maximum rate.
    • Tear delay decreases are more noticeable and are a greater increase to DPS when the tears stat is high.
  • (in Repentance) +0.5 fire rate.
  • (except in Repentance) The head orbital deals 7 damage per tick or 105 damage per second.
  • (in Repentance) The head orbital deals 7 damage per tick or 56 damage per second.

Notes[]

  • (in Repentance) Isaac's body will spew a fountain of blood like a GusherGusher. This is purely cosmetic.
  • While Isaac's actual hitbox (his body) does not change, the position of the head can obscure the body's exact position, making things such as dodging or collecting pickups more difficult.
  • Items that apply contact damage and effects (Collectible The Virus iconThe Virus, Collectible Aries iconAries, etc.) do not apply to the head.
  • The head orbital ignores the normal three orbital cap used by items such as Collectible Cube of Meat iconCube of Meat and Collectible Sacrificial Dagger iconSacrificial Dagger.
  • The orbital is larger than most other orbitals, making it easier to use both offensively and defensively.
    • Despite changing size with Isaac, the orbital's hitbox does not change, which can be deceptive.
  • Standing near a wall may cause the head to go inside the wall while rotating, blocking tears.

Synergies[]

  • Collectible BFFS! iconBFFS!: Although the head doesn't increase in size, doubles the contact damage.
  • Collectible Big Fan iconBig Fan: Slows down the head orbital, making it easier to aim.
  • Collectible Guardian Angel iconGuardian Angel: Does not increase the head's rotation speed.
  • Spectral tears: Prevents shots from being blocked by walls, making it easier to fire.

Interactions[]

Overrides Guillotine's firing pattern:

Other interactions:

  • (except in Rebirth)Collectible Box of Friends iconBox of Friends/(in Repentance)The TwinsThe Twins: Adds another rotating head, but only the original head will fire tears.
  • Collectible Guillotine iconGuillotine: Each additional copy adds another orbital and increases stats, but only the original head will fire tears.
  • (in Afterbirth †)Duct TapeDuct Tape: Causes tears to be fired from far below and to the right of Isaac. This causes tears to be out of bounds unless Isaac is standing in the top-left corner of the room.
  • (in Repentance) Duct TapeDuct Tape: Tears are fired from whatever position the head is stuck in.
  • Collectible The Pinking Shears iconThe Pinking Shears/Collectible Transcendence iconTranscendence: Removes Isaac's body aside from a small shadow. This can make Isaac's position even more confusing.
  • (in Afterbirth † and Repentance)Collectible Sacrificial Altar iconSacrificial Altar: The head orbital cannot be sacrificed.
  • (in Repentance) Collectible Scissors iconScissors: The head created by Scissors fires tears, while the head created by Guillotine only acts as an orbital.
  • (in Repentance)Collectible Spin to Win iconSpin to Win: Affects the head, which boosts its damage and defense properties but makes shots harder to hit.
  • (in Repentance) Collectible Tiny Planet iconTiny Planet: Tears fire from the head and orbit around the body.

In-game Footage[]

Trivia[]

  • A guillotine is an execution device that kills by severing its victim's head. It gained notoriety during the French Revolution where it was used to kill 17,000 people during the period known as the "Reign of Terror."
  • If Isaac has items that visually change his hands, the effect applies to Isaac's head too. For example, when having (except in Rebirth)Collectible Bursting Sack iconBursting Sack, Isaac's body and head will both hold a sack while there are two extra hands added to the head.
