Geminus is a familiar in Glacier's Laboratory, a mod for The Binding of Isaac.

Spawns a slime baby familiar that follows Isaac around.

Upon entering a hostile room, it mimics a random non-boss monster inside the room and fights on Isaac's side.

If there isn't any non-boss enemy in the room, slime baby will take the form of a monster it previously transformed into. If it still has nothing to mimic, it will take the form of a Cyclopia instead.

Monsters that are transformed from slime baby have more health, bigger size, acts faster and deal +1 collision damage.

After taking enough damage, slime baby will discard its mimic form and starts to jump torward enemies. Each jump creates 2 slime splashes, with a 1 second delay between each jump.

Slime splash shoots 3~6 slime tears in random direction, these tears stick onto enemies and deal 1 damage each. It also creates a green creep that slows enemies down.

This item contributes towards the Conjoined transformation. Collecting 3 items from this set will make Isaac shoot in 3 directions at the cost of -0.3 damage and -0.3 tears.
