I was wondering if we can sell off ranked 5 low level monsters and if in the future books they will still count even though you no longer have them?
I've had 3 legends bobbing around in hatchery waiting for SP to give us more habitats...have missed breeding challenges and a lot of things cause I can't use hatchery.....since the libraries you cant get rid of all those useless monsters...HELP

@Haka-Taka are you sure? 'Cos I have been given the rewards of finished chapters, even though I had sold those hatched minions before the books came out...pre ranked minions

They will add a feature to store some monsters or so they plan on anyway.
If you can wait for it for another 2-3 months, that's great. If not, and to my knowledge, selling a monster doesn't prevent it from being "collected" in future books.
This could change at any given time tho. Either way, i am keeping mine and suffering until the storage is there.

thanks for the thoughts appreciate your replies
