Not to be confused with Blood Clot, an item.

Added in Repentance

Lil Clot is a trinket added in The Binding of Isaac: Repentance.


  • Spawns a 15►Sumptorium Sumptorium blood clot Familiar on the ground next to Isaac. This familiar moves and shoots through the same inputs as Isaac, effectively acting as a second source of tears.
  • The familiar uses Isaac's tears, range, shot speed, and tear effects, and deals 0.35x Isaac's damage.
  • Lil Clot will die after it gets hit 3 times, and will respawn when entering a new room.


  • Holding the "drop" button lets Isaac move independently from Lil Clot.
  • Lil Clot will persist after the trinket is dropped, but it will not respawn unless the trinket is picked up again.
  • Lil Clot spawns in a random location near Isaac when the trinket is first picked up.
  • Duplicating Lil Clot trinkets will cause them to stack, allowing Isaac to control multiple Lil Clots at once.


  • 15►BFFS! BFFS!: Increases the damage to 70% of Isaac's.
  • Found Soul Found Soul: The ghost familiar receives its own floating Lil Clot that acts the same way as Isaacs's, vanishing when the ghost dies.
  • 15►Mom's Box Mom's Box: Summons an additional Lil Clot.
  • 15►Tractor Beam Tractor Beam: Lil Clot's tears travel along the beam regardless of the location of Lil Clot.

In-game Footage[]


Bug Bug! When used together with Azazel's Stump Azazel's Stump, the blood clot familiar sometimes keeps Azazel's properties (flight and short brimstone) for a few rooms after you have transformed back from Azazel into your original character. Found Soul Found Soul also has this bug.
Bug Bug! PC If Isaac has both 15►The Ladder The Ladder and a form of flight, the clot familiar will be unable to path over any terrain with a ladder on it despite having the ability to fly, resulting in movement desync.
