Added in Repentance

Esau Jr. is an activated item added in The Binding of Isaac: Repentance.

Effects[]

  • When used, swaps between the current character and Esau Jr., who has three black hearts, +2 flat damage, and flight.
    • Despite starting with only black hearts, Esau Jr. is able to gain heart containers.
  • Coins, bombs, and keys are shared between the two characters, but everything else (including hearts, items, cards/pills, and trinkets) are not shared and apply only to the character that collects them.
    • Esau Jr. will have the same base stats, character-specific abilities and passive starting items (such as Lilith Lilith's blindfold and 15►Incubus Incubus) as the original character.
      • The only exception is Eden Eden/Tainted Eden Tainted Eden, who will have different stats and passive starting items.
  • When used for the first time, Esau Jr. immediately gains random items equal to the number of items the original character had.
    • Each new item will come from the same item pool the respective original item was taken from, similarly to the 15►D4 D4.
    • Substitute Trinkets, Cards, Pills, and/or Active items are not given; only passive items are.
    • Quest items like 15►The Polaroid The Polaroid and set drops like 15►The Small Rock The Small Rock are not included when counting the number of items.
    • Any pickups that would normally be generated by the new items will all simultaneously drop when Esau Jr. is first used.
  • If either character dies, they both die, regardless of whether the other character has any remaining health.

Notes[]

  • The item may have severely glitchy interactions with some characters. Refer to the bugs section.
  • Esau Jr. will keep any passive starting items the original character had; however, if said item(s) are rerollable, they will still count towards the number of items Esau Jr. will get.
  • If the original character was only able to use certain kinds of hearts for health (such as ??? ???, Keeper Keeper, or The Forgotten The Forgotten), Esau Jr. will only be able to use the hearts the original character could.
  • Unlike revival items like 15►Lazarus' Rags Lazarus' Rags, 15►Judas' Shadow Judas' Shadow, Missing Poster Missing Poster, or 15►Ankh Ankh, Esau Jr. is still treated as the character he swapped from for the purposes of Post It Notes.
  • If an inactive character has an eternal heart when the active character goes to a new floor, the eternal heart will turn into a heart container when that character becomes active again.

Interactions[]

  • 15►Chaos Chaos/15►Sacred Orb Sacred Orb/15►TMTRAINER TMTRAINER: Will affect the items given to Esau Jr. when used for the first time, but will not affect subsequent uses. Item generation is only affected if the character that has it is currently active.
  • 15►Schoolbag Schoolbag: The extra active item will continue to be held by the character that has Schoolbag. However, it cannot gain charges through any means until the character becomes active again.
  • 15►Car Battery Car Battery: Esau Jr. will only activate once, allowing it to be used normally.
  • 15►Eden's Blessing Eden's Blessing: The extra item given from turning into Esau Jr. for the first time will be different from the one given by Eden's Blessing.
  • 15►Book of Virtues Book of Virtues: Gives a black wisp when used to turn into Esau Jr that is otherwise identical to a normal one; turning back into the original character destroys the wisp. All other wisps are retained between forms.
  • 15►Lemegeton Lemegeton: Wisps will be retained between forms. For the character that doesn't have Lemegeton, the wisps effects are only updated when one of them is destroyed.
  • 15►Isaac's Tomb Isaac's Tomb/15►Voodoo Head Voodoo Head/15►Dream Catcher Dream Catcher/15►Card Reading Card Reading/15►Blood Oath Blood Oath/15►Luna Luna: The character that has the item must be active going to a new floor for it to have its effect.
    • In the case of Luna, the character that has the item must also be active going into Secret Rooms for them to spawn beams of light. However, either character can then enter the beam of light to gain tears and soul hearts.
  • 15►Missing No. Missing No./15►Empty Heart Empty Heart: If the character that has the item is inactive going to a new floor, it will activate for them immediately when they become active.
  • 15►Lost Soul Lost Soul: The soul respawns every time the character that has Lost Soul becomes active. If it's the first time Lost Soul spawned after going to a new floor, it will give a reward, regardless of whether or not it died on the previous floor.
  • Panic Button Panic Button: Activates Esau Jr. before the active character takes damage, redirecting the damage to the inactive character. The item's charge is used in the process.
  • Keeper Keeper/Bethany Bethany/Tainted Keeper Tainted Keeper: Esau Jr will have one heart container, but can still gain heart containers up to the character's normal cap.
    • In the case of Bethany, Soul Hearts will still be used as soul charges instead of health.
  • The Forgotten The Forgotten: If used as The Forgotten, Esau Jr. will have three empty bone hearts and the bone club, and cannot gain soul hearts. Both forms will also be unable to turn into The Soul. If used as The Soul The Soul, Esau Jr. will not be bound to The Forgotten's Body. If used again to turn back into The Soul, The Forgotten's Body will also be summoned alongside them, but the player cannot turn back into them, preventing them from moving between rooms and causing a softlock.
  • Tainted Magdalene Tainted Magdalene: Esau Jr.'s starting black hearts will quickly drain down to half a heart; he must obtain heart containers while in this form to have any survivability.
  • Tainted Cain Tainted Cain: The items given to Esau Jr. on the first use are based on the item pool of the first room Tainted Cain gained an item from. Other abilities are unchanged.
  • Tainted Eden Tainted Eden: Taking damage will turn Esau Jr. back into Tainted Eden, along with all of its other effects. Tainted Eden's health before transforming into Esau Jr. will not be recovered.
  • Tainted Jacob Tainted Jacob: Esau Jr. takes half a heart of contact damage from Dark Esau instead of turning into a ghost. Dark Esau's death explosion also does not affect him.

Bugs[]

Bug Bug! if used as Jacob & Esau, two things will happen depending on who used it. If used as Esau, the game file will corrupt, causing progress to be lost from that save file. If used as Jacob, Esau will be deleted alongside all his associated items. NOTE: these exact outcomes may not happen, but it is advised that you dont use Esau jr as Jacob & Esau as it may lead to consequences such as progression loss and file corruption, your discretion is advised.
Bug Bug! If Esau Jr. is overcharged (using 15►The Battery The Battery, Bethany Bethany/Tainted Bethany Tainted Bethany's soul/blood charges, a Battery Bum, or a Mega Battery), using it has a chance to cause the character transformed into to play at double speed. This includes having doubled speed and tears, halved invulnerability frames after taking damage, and halved duration for Temporary buffs. This effect can stack additively if Esau Jr. is overcharged before using it again. If this effect is caused by using soul/blood charges, all the charges will be consumed and the effect will stack up to the number of charges consumed. If this effect does not occur on use, the character's play speed is set back to their normal amount.
Bug Bug! The Lost The Lost and Tainted Lost Tainted Lost die immediately if they use Esau Jr.
Bug Bug! Tainted Forgotten Tainted Forgotten can turn into Esau Jr. without gaining the ability to move, and turning back removes Tainted Soul Tainted Soul, making it impossible to continue. Trying to quit and resume the game causes a crash.
Bug Bug! Using this item as Tainted Lazarus Tainted Lazarus replaces both versions' spacebar items with it, and will re-replace any other spacebar items if one version keeps Esau Jr and the other exchanges it for a different spacebar item on next use; also, instead of swapping to Esau, they will swap between the two versions of Tainted Lazarus Tainted Lazarus on use.
Bug Bug! If used as Tainted Isaac Tainted Isaac, any items Esau Jr. gains on its first use do not count toward the item limit.
Bug Bug! If used while a Purgatory ghost is onscreen, the game will crash.
Bug Bug! If the debug command listcollectibles is used while transformed into Esau Jr, the game crashes.
