My data suggests Adinsx3 is correct.

Using Captain's Brooch with 3 Embryos:

66/70 times - 2 chests

4/70 times - 1 chest

Also, the shield generator lasted 16 seconds, the gold bomb did double damage, the mirror seemed to make 2 copies.

With 4 Embryos:

37/37 times - 2 chests

Decoy lasted 16 seconds, mirror made 2 visual copies, drones called 6, lasted same time, jar of souls made 2 ghosts per monster.

So it seems like the % chance is additive, maxed out at 4 embryos, and they only double the item's power regardless of quantity.
