Binding of Isaac: Rebirth Wiki

(in Repentance)
This article is about Star of Bethlehem, similar in appearance to Eden's Soul.

Star of Bethlehem is an unlockable passive item added in The Binding of Isaac: Repentance.

Effects[ | ]

  • Spawns a star familiar that slowly travels toward the Boss RoomBoss Room, fading through doors as it travels towards it. Once it reaches the boss room, the familiar stands in the center of the boss room for the rest of the floor.
  • The familiar emits an aura that, while Isaac stands inside it, gives him a 1.8x damage multiplier, a 2.5x fire rate multiplier, and homing tears. It also gives Isaac a 50% chance to ignore damage similarly to Collectible Cone Head iconCone Head's effect except with a higher chance.

Notes[ | ]

  • In The VoidThe Void, the familiar will travel to the boss room that contains Boss Delirium ingameDelirium.
  • In Greed Mode, the star will travel directly to the position where Isaac spawns upon entering a new floor.
    • On the last floor, it will move to the upper part of Boss Ultra Greed ingameUltra Greed's room.
  • Once the star settles down in the boss room, the damage preventing aura can be used to play Blood Donation MachineBlood Donation Machines and Devil BeggarDevil Beggars for free, provided they are spawned via XIV - TemperanceXIV - Temperance or XX - JudgementXX - Judgement cards, respectively.
  • The star may travel through Secret RoomSecret Rooms and Curse RoomCurse Rooms on its path to the boss room.
  • The star will travel through Red RoomRed Rooms if they create an optimal path to the boss room.
    • The star can backtrack into rooms it already went into if a more optimal path is created by a Red Room.
  • During the Ascent, the star will linger in the boss room of each floor, and will not progress backwards through the stage.
  • The star will be present against Boss Dogma ingameDogma, but does not follow for Boss The Beast ingameThe Beast
  • If the door to Mega Satan Head ingameMega Satan is opened, the Star of Bethlehem will enter it instead of the boss room containing Boss ??? ingame??? or Boss The Lamb ingameThe Lamb.
    • The Star will move backwards towards the Mega Satan Head ingameMega Satan's door, if the door is open later during the floor, with Collectible Dad's Key iconDad's Key, for example.
  • For Character Tainted Forgotten iconTainted Forgotten, the bonuses from the star are only applied if Tainted Forgotten is within its aura, not Character Tainted Soul iconTainted Soul.
  • If either Character Tainted Lazarus iconTainted Lazarus or Character Dead Tainted Lazarus iconDead Tainted Lazarus have picked up the star, the familiar will spawn in the room where the character holding it becomes active, which may not be the starting room. It will only move while the character holding it is active, effectively making it take twice as long to travel to the boss room unless Tainted Lazarus also has Collectible Birthright iconBirthright.
  • During Backasswards (challenge #31), the star acts as usual; originating in the starting room and gradually moving towards the boss room.
  • The star will be copied in the Mirrored World and will simultaneously travel in both worlds.
  • Entering and leaving the Collectible Knife Piece 2 iconKnife Piece 2 area will reset the star and make it reappear in the room with the minecart.
  • The star exhibits a "rubber banding" effect in its movement. If it is in a room that is closer to the Boss Room than the one Isaac is in, it will move slower; if the opposite is true, it will move faster.

Trivia[ | ]

  • This item is a reference to the Star of Bethlehem which appears in the Nativity story of the Gospel of Matthew, signifying the birth of Jesus.

Bugs[ | ]

Bug Bug! If Isaac uses Collectible Pause iconPause, the light aura will be stuck in the last position before Pause was used even if the familiar continues without it. This is only a visual glitch, Isaac still has to be near the star to receive its benefits. If Pause’s effect ends the light instantly disappears and respawns back around the star again. The light will still fade when the star leaves the room.
