Lil Portal item
Lil Portal is an unlockable familiar in The Binding of Isaac, added in the Repentance DLC.
Description
Spawns a familiar that follows Isaac and launches itself in the direction Isaac is shooting, and deals contact damage to enemies.
The familiar will consume pickups and trinkets in its path, converting them into Blue Flies and increasing its size.
Damage dealt by the familiar is equal to 2 × ConsumablesDestroyed + 2 per tick, ticking up to 10 times per second.
