Character Tainted Cain iconTainted Cain Salvage The amount of pickups dropped from collecting an item is doubled.
Character Judas iconJudas Belial incarnate Collectible The Book of Belial iconThe Book of Belial becomes a passive item that can be held beneath other active items, similar to Collectible Book of Virtues iconBook of Virtues. May stack with Book of Virtues. If Judas is not currently holding The Book of Belial, he receives it. The damage boost received from The Book of Belial scales with the amount of charges the active item above it has; may not work with one-time-use items, items with unlimited use, timed recharges or items that do not follow normal room charge rules (Collectible Isaac's Tears iconIsaac's Tears, etc). Has special interactions with certain items - see The Book of Belial for more information.

Character Tainted Lazarus iconTainted Lazarus Superposition The non-active form of Tainted Lazarus will appear in ghostly form, being completely immune to damage and dealing 25% damage (including tear effects such as Collectible Holy Light iconHoly Light). Holding down the "drop" key allows the active form to move independently of the other form, similar to Character Jacob and Esau iconJacob and Esau. Using Collectible Flip iconFlip will cause the two characters to switch states while maintaining positions. Both characters receive the Birthright effect when one character collects it.
Character Dead Tainted Lazarus iconDead Tainted Lazarus
Character Eden iconEden ??? Creates 3 random items from random item pools. Only one can be taken. Ignores item weight and can spawn items that have already been taken during the run. Can also spawn multiples of the same item, if they exist in multiple item pools.

Character Tainted Lost iconTainted Lost Extra life Grants an extra life that revives Tainted Lost in the same room and deals 200 damage to nearby enemies. It can hit the same enemy up to 4 times.
Character Lilith iconLilith Offensive Formation Most familiars that normally follow Lilith, including Lilith's innate Collectible Incubus iconIncubus, will always be positioned in front of Lilith, creating a stack, facing whatever direction she was shooting. Non-attacking familiars (Collectible The Relic iconThe Relic, Collectible Farting Baby iconFarting Baby, etc.) will follow Lilith's most recently acquired attacking familiar instead; if the most recent familiar is throwable like Collectible Holy Water iconHoly Water, familiars following it will also be launched with it. If Lilith has Collectible King Baby iconKing Baby, it will always be positioned directly in front of Lilith with all other affected familiars forming a semi-circle around it, and will behave normally otherwise. Collectible Dry Baby iconDry Baby is considered an "attacking familiar" and will be within the stack. Collectible Lil Portal iconLil Portal and Collectible Jaw Bone iconJaw Bone are exempt and behave normally.
Character Tainted Lilith iconTainted Lilith Conjoined Familiars that normally follow Tainted Lilith will instead act like and stack on top of her Collectible Gello iconGello familiar, disappearing inside of her while she's not firing and swinging out when she attacks. The melee attack gains a flat +3 damage bonus per familiar (regardless of damage multipliers) and if those familiars can shoot, they do so along with the Gello familiar. The Gello familiar gains the properties of Collectible King Baby iconKing Baby, causing attached familiars to automatically aim and shoot at enemies. Familiars like Collectible Jaw Bone iconJaw Bone or Collectible Holy Water iconHoly Water still function, but they are bound to the Gello familiar rather than their normal means of movement.
Character Keeper iconKeeper Coin up Adds one Coin Heart and raises Keeper's maximum Coin Heart limit to 4.
Character Tainted Keeper iconTainted Keeper Money money money Strongly attracts the coins dropped by killed enemies from a short distance. No effect on other coins.
Character Apollyon iconApollyon Regurgitate Using Collectible Void iconVoid has a 10% chance to spawn one previously destroyed passive item (while keeping the bonus stats). Each absorbed passive item has an equal chance to be spawned. Spawned items can be spawned again even if they are not reabsorbed. Absorbing duplicates of the same item will make it more likely to be spawned, as each duplicate counts as a separate item and thus has its own chance to be spawned. Birthright has no effect if Void is not held.
Character Tainted Apollyon iconTainted Apollyon Torment Holding down the fire button causes Collectible Abyss iconAbyss locusts to continuously damage enemies instead of returning.
Character The Forgotten iconThe Forgotten Unchained Character The Soul (Character) iconThe Soul is unchained and free to move. It can move to different rooms, leaving The Forgotten behind, and switching back teleports The Soul back to The Forgotten.
Character Tainted Forgotten iconTainted Forgotten Recall Character Tainted Soul iconTainted Soul is given Collectible Recall iconRecall, an unlimited-use active item which pulls Tainted Forgotten into its hands automatically from a distance, dealing damage to enemies as it travels.
Character Bethany iconBethany Conserve your faith Activating an item using Soul Charges is free 50% of the time.
Character Tainted Bethany iconTainted Bethany Artifact Spawns four Collectible Lemegeton iconLemegeton wisps of items with a quality of 3 or higher. These wisps are much larger and have much higher HP than normal wisps.
Character Jacob and Esau iconJacob and Esau What's yours is mine The character who picks up Birthright gains copies of the three most recent passive items from the other.
Character Tainted Jacob iconTainted Jacob It's not yours Dark EsauDark Esau splits into two. Both Esaus will always charge at the same time, and one will not charge if the other is not in position. Using Collectible Anima Sola iconAnima Sola chains both Dark Esaus at once and forces them together into one spot. Subsequent uses release each Dark Esau one at a time. Anima Sola's recharge time is reduced to 10 seconds, and chain duration is increased to 6.67 seconds.

Notes[ | ]

  • Birthright effects are stackable when playing as Character Tainted Lost iconTainted Lost and Character Tainted Bethany iconTainted Bethany.
  • Each additional copy of Birthright for Character Magdalene iconMagdalene, Character Tainted Magdalene iconTainted Magdalene, and Character Keeper iconKeeper will add another heart container, however their respective health caps will not be raised any further. Character Cain iconCain will also gain +1 Luck for each copy of Birthright.
  • When Character Magdalene iconMagdalene or Character Keeper iconKeeper enter the area in which Collectible Knife Piece 2 iconKnife Piece 2 can be acquired, all hearts above the usual cap are removed and are not restored upon leaving the area. Additional hearts can be regained afterwards.
  • While playing as Character Tainted Cain iconTainted Cain in Greed Mode, purchasing an on-sale item over and over while having Birthright results in almost infinite consumables.

Trivia[ | ]

  • Birthright is from the Antibirth mod.
    • Before Antibirth the item originated from the Binding of Isaac: Community Remix mod, where it was known as 'Soul Script'.
  • This item's name, description, and unlock requirement are likely a reference to the biblical story of Jacob and Esau, in which Esau trades his birthrights to Jacob in exchange for stew.
    • When Character Tainted Jacob iconTainted Jacob picks up Birthright, Dark EsauDark Esau, a representation of his own rage, seemingly becomes only angrier and doubles in power.
      • Birthright's effect doubling Dark Esau's power,instead of Tainted Jacob's, and the quote "it's not yours", further reflects the fact that it was originally his.
  • Prior to patch V1.7.6, Tainted Jacob's Birthright pickup quote was "There is no escape".
  • Tainted Keeper's pickup quote could be based off the song made by ABBA, "Money, Money, Money"
  • Tainted Forgotten's pickup quote may be a play on words, as for recall can also mean to remember.
  • Eden's Birthright could be a reference to how Eden functions in the card game The Binding of Isaac: Four Souls, as Eden starts the game by drawing 3 treasure cards and selecting one to keep permanently while the other two are discarded.
