Binding of Isaac: Rebirth Wiki

Added in Repentance

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


  • Spawns a wisp that orbits Isaac, fires tears, blocks enemy shots, and deals contact damage to enemies, much like the ones spawned by Book of Virtues Book of Virtues.
    • The jar initially spawns only one wisp, but spawns an additional wisp each time the jar is used, up to a maximum of 12 per use. The amount of wisps that will be spawned by the jar is indicated by both a counter and the jar visually filling up with wisps.
  • Isaac can have up to 3 rings of wisps; an inner, counter-clockwise spinning ring of 6 wisps, a center, clockwise-spinning ring of 8 wisps, and an outer, counter-clockwise spinning ring of 12 wisps, for a total of 26.



  • Car Battery Car Battery: Only spawns one extra wisp per use, regardless of the current wisp count.
  • Void Void: Will spawn only one wisp per use.


  • The wisps spawned by the jar can be ones created by any Book of Virtues synergy, although basic wisps are much more common than special variants.
  • While most wisps that can be given act similarly to normal wisps, there are some with effects that can potentially harm Isaac.
    • Anarchist Cookbook Anarchist Cookbook Wisps look like bombs and spawn Troll Bomb Troll Bombs when destroyed.
    • Wisps that look like gray cubes will invoke the effect of the D7 D7 when they take damage. If this happens during a Boss fight, Isaac will be teleported to a random room on the floor, which will have its enemies respawned.
      • Teleport! Teleport!/Teleport 2.0 Teleport 2.0 Wisps fade into and out of existence and have a chance to teleport non-boss enemies to a random spot in the current room when their tears hit them.
  • Switching the jar with other active items and then picking it up again does not reset the number of wisps that will be spawned on use.
