Effects[]

Notes[]

Synergies[]

  • 15►Mom's Box Mom's Box: Has an additional 50% chance to trigger the effect again, resulting in another familiar doubling. This can be the same familiar that was doubled originally.

Interactions[]

  • Movement-mimicking familiars: Duplicated familiars will follow the original on the same delay.
    • In the case of 15►Shade Shade, a copy of the familiar will spawn even if Shade was already absorbed by Isaac.
  • Pickup-generating familiars: If they remain duplicated for enough consecutive rooms, they will give a pickup as normal. The following familiars have to be duplicated for the following number of consecutive room clears to give pickups:
  • 15►Cambion Conception Cambion Conception/15►Immaculate Conception Immaculate Conception: Familiars given by these items can be duplicated as normal.
  • 15►Bum Friend Bum Friend/15►Dark Bum Dark Bum/15►Key Bum Key Bum/15►Bumbo Bumbo/15►Lil Portal Lil Portal: The pickup count of duplicated familiars is not remembered when they go away.
  • 15►Ball of Bandages Ball of Bandages/15►Cube of Meat Cube of Meat: Upgrades the familiar instead of duplicating it.
  • 15►Best Bud Best Bud/15►Bird Cage Bird Cage: If the trinket tries to duplicate it, it will instead immediately activate. Taking damage does not spawn another familiar.
    • If this happens to Bird Cage as Isaac walks into a room with enemies, Bird Cage will also leap onto the enemies.
  • 15►Blood Puppy Blood Puppy/15►Bumbo Bumbo/15►Guppy's Hair Ball Guppy's Hair Ball: The duplicate will always be at its first stage.
  • 15►1up! 1up!: Despite the fact that it can be duplicated, Isaac will not keep the 1up if he dies while it's duplicated.
  • 15►Guillotine Guillotine: The head can be duplicated, and will give an extra damage and tears up if it is. The extra head will be unable to fire tears.
  • 15►GB Bug GB Bug: The familiar can be duplicated even if it hasn’t respawned; by constantly moving to new rooms, GB Bug can constantly respawn, allowing pickups to be rerolled indefinitely.
  • 15►Succubus Succubus: The damage multiplier from standing in the aura of multiple Succubi multiplicatively stacks.
  • 15►Buddy in a Box Buddy in a Box: The duplicated familiar will be randomly generated instead of copying the original.
  • 15►Hallowed Ground Hallowed Ground: Duplicate poops will also drop when Isaac takes damage. The bonuses from standing in the aura of multiple white poops does not stack.
  • 15►YO LISTEN! YO LISTEN!: An extra +1 luck will be given for every duplicate.
  • 15►Mystery Egg Mystery Egg: The friendly the duplicated egg spawns depends on how many consecutive rooms cleared the duplicate persisted for.
  • 15►Lost Soul Lost Soul/15►Star of Bethlehem Star of Bethlehem: The trinket can try to make a duplicate of the familiar, but it will always fail. This reduces the odds of the trinket giving copies of other familiars or prevents it from giving Brother Bobby or Sister Maggy if he has no other familiars.
  • Soul of Lilith Soul of Lilith: Familiars given can be duplicated as normal.
  • 15►Strawman Strawman: Keeper cannot be duplicated, as he is considered a character, not a familiar.
