Intel requested (Ch 13+)

It's probably too early to ask this question because it's post game and it's only been out a week but feel free to ask item/ mission related angst and I'll try and sleuth out the answer for you.

Ch-13+ (SPOILER)
One growth egg give you x2 exp for your entire team
example1: cactaur = 5,000 exp
example2: cactaur with growth egg equipped = 10,000exp
Question: cactaur with 2 growth eggs equipped = 15,000exp? or 20,000exp?
anyone know the answer? (SPOILER)
I'm going to attempt a second egg but didn't wanna waste the time if someone knew.


BE WARNED!!! Your character cannot hold more than 999,999cp, any more and you waste it

I don't know if you can stack them. Try it and let me know. I have just been doing missions.

You only get Growth Egg once.
