Not to be confused with Blood Clot, an item.

Added in Repentance

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


  • Spawns a 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.


  • 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 Isaac's, vanishing when the ghost dies.
  • Golden Trinket Golden Trinket / Mom's Box Mom's Box: Summons an additional Lil Clot.
  • The Ludovico Technique The Ludovico Technique: The clot's tear floats the same way Isaac's tear does. Additional clots gained from Mom's box, Found Soul, and golden versions of the trinket will have an additional floating tear.
  • 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 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.
