ever get that msg? i got it when i was finally able to give my monster some food. its an event and ya gotta go talk to yer monster, anyway, what is this good that happens?

i've retired and raised a 2nd gen and nothing happened. my stats still decreased, all my monsters are still unmotivated, what gives?

You have to wait until you get a message that says your monster is too old to earn more stats and anima points (or something like that) and the offspring's parameters will increase, otherwise, it will lower them or it won't do anything! Now remember that both of the monsters that you are combining have to have had that exact phrase spoken from Nayuta.

Spacifically one week nayuta will tell you that "name" has reached their full potential! you should try combining it now! Im sure it will have great children! IM pretty sure thats the message to look for word for word. It doesnt mean you need to seal the monster, just that it is safe to do so at that point if you want the bonuses... aging is alot diffrent in this game.

monsters can still gain anima points in adventures after they reach their full potensial,and they can still perform in shows. but thy will not benifit from stat gains.
my favorite evilbeak ended up with something like 60000+ extra anima points before i sealed him lol.
