Binding of Isaac: Rebirth Wiki

(in Repentance)

Lemegeton is an unlockable activated item added in The Binding of Isaac: Repentance.

Effects[ | ]

  • Upon use, Lemegeton will grant a random passive item as an orbital familiar. The item summoned has a 25% chance to be from the current room's Item Pool, or from a random item pool otherwise. The item must have the 'summonable' item tag in order to be generated.
    • These familiars can block up to 4 shots and/or get hit by 2 explosions before being destroyed. When the familiar is destroyed, the item it granted is lost.
    • Familiars also deal contact damage to enemies equal to 2x Isaac's damage per tick (4x Isaac's damage per second). They do take contact damage.
    • Isaac can have up to 26 familiars: an inner counterclockwise ring of 6, a middle clockwise ring with 8, and an outer counterclockwise ring of 12.
      • Using Lemegeton while Isaac already has 26 causes the oldest one to be replaced.
  • This item belongs to the BookwormBookworm set. Collecting three items from this set will transform Isaac into Bookworm.

Notes[ | ]

  • Character Tainted Bethany iconTainted Bethany starts with this item in the consumable slot.
    • When playing as Tainted Bethany, picking up Collectible 4.5 Volt icon4.5 Volt will cause Lemegeton to no longer gain charges as long as her normal active item has empty charges.
  • Items given by Lemegeton are separate from the normal item pools and Isaac's current collection of items. This has the following effects:
    • Isaac can still normally find items that were previously summoned by Lemegeton.
    • Isaac can have multiple wisps of the same item.
    • Wisps cannot be rerolled by Collectible Missing No. iconMissing No. or the Collectible D4 iconD4 / Collectible D100 iconD100.
    • Wisps do not count towards transformations.
      • Super Bum is an exception and can be gotten from wisps
    • Summoned items do not count towards the Collection Page.
  • Items that would normally add or remove hearts/consumables (such as Collectible Boom! iconBoom!, Collectible Breakfast iconBreakfast, Collectible Abaddon iconAbaddon etc.) do not do so if given by Lemegeton.
  • Summoning a Collectible Birthright iconBirthright wisp grants Character Tainted Lost iconTainted Lost infinite lives until the wisp is destroyed.

Bugs[ | ]

Bug Bug! After using Collectible Genesis iconGenesis, Isaac keeps the passive effects of each wisp until the next use of Lemegeton, which erases all lingering wisp effects.
Bug Bug! If a run is exited and resumed while Isaac has item wisps generated from Lemegeton, all wisps will be condensed into the middle clockwise ring, even if this would result in more wisps on that ring than normally allowed. This also allows further wisps to be generated on the inner and outer rings.
Bug Bug! Each use of Collectible Glowing Hourglass iconGlowing Hourglass that does not move Isaac to a different room from the one he is currently in (such as by teleporting to the previous room then using it again) will duplicate the wisps. Creating wisps in this way allows Isaac to exceed the item's wisp limit.
