Added in Repentance

Plum Flute is an activated item added in The Binding of Isaac: Repentance.


  • On use, summons Baby Plum to fight for Isaac in the current room for ~10 seconds.
    • Baby Plum will always twirl, jump, then spit blood and bounce around the room before waving goodbye and flying away.
    • Baby Plum does 12 contact damage per tick (24 per second), 3.5 damage per shot, and 2 damage per tick with creep (20 per second).
  • This item belongs to the Beelzebub set. Collecting three items from this set will transform Isaac into a giant humanoid fly.


  • If Isaac goes enough time (about half a minute) without hurting Baby Plum during a boss fight, she will fly away and leave behind a Plum Flute on the Boss Room pedestal.


  • Angelic Prism Angelic Prism: Baby Plum's shots that pass through the Prism will be refracted.
  • BFFS! BFFS!: Doubles Baby Plum's contact damage, but not projectile damage.
  • Car Battery Car Battery: Summons two Baby Plums, the Baby Plums start out overlapped but can sometimes split up when using different attacks.
  • Lost Cork Lost Cork: Affects Baby Plum's blood puddle.
  • Sacrificial Altar Sacrificial Altar: Baby Plum can be sacrificed for free, instead of a familiar. Plum Flute can still be used as normal afterwards.


  • Book of Virtues Book of Virtues: Spawns a wisp on the middle ring, resembling Baby Plum. When the Baby Plum spawned from using Plum Flute bounces diagonally around the room, all the wisps will bounce around the room and fire tears behind themselves as well. The wisps are invulnerable while bouncing around the room.
  • Eraser Eraser: If Baby Plum(the boss) is erased, Plum Flute will remain unaffected.
