Birthright is a passive item added in The Binding of Isaac: Repentance.

Effects

• Grants a passive ability that varies from character to character. The effect usually enhances the character's special traits.

Character	Pickup Quote	Effect
Isaac	More options	All new item pedestals cycle between two options. Previously-seen items are unaffected.
Magdalene	Limit breaker + HP up	Adds 1 full Heart Container. Increases the maximum heart limit to 18.
Cain	Better arcades + luck up	+1 Luck. All floors will contain an upgraded Arcade that generally contains more Machines except for Chest / Dark Room. This includes odd-numbered floors, Cathedral, and Sheol. Arcades will appear even if Cain is not holding at least 5 Coins. Greatly increases Lucky Foot's chances of winning effect.
Judas	Belial incarnate	The Book of Belial becomes a passive item that can be held beneath other active items, similar to Book 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 (Isaac's Tears, etc). Has special interactions with certain items - see The Book of Belial for more information.
Dark Judas
???	Stronger spirit	Soul Hearts gained from HP ups are doubled.
Eve	Forever cursed	Whore of Babylon is active regardless of health and Dead Bird is active without taking damage.
Samson	Rage up	Bloody Lust can gain 4 more Damage boosts at the same +0.2 intervals, for a new maximum total of +14.0.
Azazel	Wide breath	Azazel's Brimstone beam becomes much wider like Mega Blast, with 2x larger collision area. No effect on damage.
Lazarus	Come back stronger	No direct effect. The item is triggered if Lazarus dies and becomes Lazarus Risen.
Lazarus Risen	Temporary DMG up	Grants a slowly fading +21.6 Damage bonus.
Eden	???	Creates 3 random items from random item pools. Only one can be taken.
The Lost	Better destiny	Prevents items with the nolostbr item tag from appearing. In practice, this automatically re-rolls most items that aren't beneficial to The Lost, namely ones that only give health, flight, and/or spectral tears or activate upon taking damage.
Lilith	Offensive Formation	Most familiars that normally follow Lilith, including Lilith's innate Incubus, will always be positioned in front of Lilith, creating a stack, facing whatever direction she was shooting. Non-attacking familiars (The Relic, Farting Baby, etc.) will follow Lilith's most recently acquired attacking familiar instead; if the most recent familiar is throwable like Holy Water, familiars following it will also be launched with it. If Lilith has King 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. Lil Portal and Jaw Bone are exempt and behave normally.
Keeper	Coin up	HP up. Raises Keeper's HP cap by 1.
Apollyon	Regurgitate	Using Void has a chance to drop an item previously destroyed by it while keeping the bonus stats. The more items absorbed into Void, the higher chance for an item to drop upon activation. Has no effect if Void is not held.
The Forgotten	Unchained	The 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.
Bethany	Conserve your faith	Activating an item using Soul Charges is sometimes free.
Jacob and Esau	What's yours is mine	The character who picks up the item gains copies of three of the other brother's passive items.
Tainted Isaac	Inventory up	Adds 4 more slots for passive items. Does not consume a slot itself.
Tainted Magdalene	HP up!	Adds 1 more Red Heart that doesn't drain.
Tainted Cain	Salvage	The amount of pickups dropped from collecting an item is doubled.
Tainted Judas	Extended darkness	Doubles the effect duration of Dark Arts (currently bugged and not working).
Tainted ???	Poop up	Increases the maximum number of carried poops to 29.
Tainted Eve	Coagulate	Red Heart Clots now spawn temporary Half Red Hearts on death that last for two seconds before disappearing. Clots spawned from other types of hearts will not drop hearts.
Tainted Samson	Unstoppable force	The berserk timer gains 3 seconds instead of 1 when Tainted Samson kills an enemy.
Tainted Azazel	Stronger sneeze	Doubles the size of Tainted Azazel's Hemoptysis sneeze attack.
Tainted Lazarus	Superposition	The non-active form of Tainted Lazarus will appear as in a ghostly form. The pair controls like Jacob and Esau, but the ghostly version is completely immune to damage. Using Flip will cause the two characters to switch states. Both characters receive the Birthright effect when one character collects it.
Dead Tainted Lazarus
Tainted Eden	Eternal	Items gained before Birthright will not be re-rolled, either by taking damage or by items such as D4 and Missing No., and base stats become locked to what they were at the time of pickup.
Tainted 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 multiple times.
Tainted Lilith	Conjoined	Familiars that normally follow Tainted Lilith will instead act like and stack on top of her Gello familiar, such that they disappear inside of her while she's not attacking and swing out when she does attack. 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. Familiars like Jaw Bone or Holy Water still function, but they are bound to the Gello familiar rather than their normal means of movement.
Tainted Keeper	Money money money	Strongly attracts the coins dropped by defeating enemies from a short distance. No effect on other coins.
Tainted Apollyon	Torment	If Tainted Apollyon holds down the fire button, locusts will continuously damage enemies instead of returning.
Tainted Forgotten	Recall	Tainted Soul is given Recall, an unlimited-use active item, which pulls Tainted Forgotten into their hands automatically from a distance.
Tainted Bethany	Artifact	Spawns four random item wisps. These have high HP and are of higher quality than normal item wisps.
Tainted Jacob	There is no escape	Dark 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 Anima Sola chains both Dark Esaus at once and forces them together into one spot. Subsequent uses release each Dark Esau one at a time.

Trivia

• This item's name 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. The reference is strengthened by the Birthright's specific effect when taken by Jacob or Esau, allowing them to "inherit" the items of their brother. This is strengthened even further by the fact that the birthright effect for Tainted Jacob (a character representation of Esau’s rage at this theft) is detrimental and only positive in very specific scenarios.

Bugs

Bug!	If Tainted Lilith has Birthright, Knife Piece 1 and Knife Piece 2's combined knife is attached to her familiar and cannot open the flesh door in Mausoleum / Gehenna II leading to the special Mom fight. This makes the path to Corpse and the Mother fight inaccessible without other means of opening the flesh door.

Bug!	Tainted Lilith's Birthright prevents GB Bug from re-rolling pickups and enemies; strangely, Lil Portal still works as expected.

Bug!	Tainted Judas's Birthright effect is non-functional and does nothing.
