Effects
While held, spawns a familiar that moves in the direction Isaac shoots. Activating the item causes Isaac to swap places with Stitches. Isaac is briefly immune to damage after teleporting.
Stitches deals 1.5 contact damage to enemies per tick (3.0 damage per second).
If Isaac teleports onto an enemy, they will take 40 + 3.5x Isaac's damage.
Teleporting next to a Fire Place will put it out, including blue fires.
Teleporting on top of a Shopkeeper will destroy them.
