Lil Clot

Not to be confused with Blood Clot, an item.

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

Effects

Spawns a blood clot Familiar on the ground near Isaac. The familiar copies Isaac's movement and attacks, but deals only 35% of Isaac's damage.
- The clot will die after taking damage 3 times.
If Isaac does not currently have a clot from this trinket, a new one spawns when entering a 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.

BFFS!: Increases the damage to 70% of Isaac's.
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 / Mom's Box / Lil Clot: Grants an additional clot, which will also respawn if the trinket is held.
The Ludovico Technique: The clot's tear floats the same way Isaac's tear does.
Tractor Beam: Clot's tears travel along the beam regardless of its location.

Bug!	When used together with Azazel's Stump, the blood clot familiar sometimes keeps Azazel's properties (flight and short brimstone) for a few rooms after transforming back from Azazel.

Bug!	PC If Isaac has both 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.
