Buddy in a Box

Effects

Grants a familiar with random tear effects, fire rate, and damage.
- The familiar's damage scales from ~2-6, and tear delay scales from ~12-30.
- The familiar takes the appearance of a random co-op baby.
- The familiar is randomized upon entering a new floor.
(Added in Repentance) This item belongs to the Conjoined set. Collecting three items from this set will transform Isaac into a three-faced version of himself.

The tear effects available are the same as on the Fruit Cake item.
The familiar's tear appearance isn't linked to the normal effect such tears would have.
- For instance, piercing-looking tears might not go through enemies and Sinus Infection tears might not stick, while tears that do not look like Compound Fracture tears can still split on hit.
Some tear effects like Proptosis and Tiny Planet do not have their associated stat boosts and thus are very ineffective.
Familiars with the Serpent's Kiss effect can drop (Black Heart) Black Hearts when an enemy is killed.
Familiars will not do contact damage.
(Added in Repentance) The familiar will change upon exiting the (Added in Repentance) Knife Piece 2 area. (possibly a bug)
