Is it okay to sell your Rank 5 uncommon or do you lose credit in the books if you get rid of them?

So let's say you are working on spirits book chapter one where there are two commons and two uncommons ranked to 5 to qualify for the rank 5 rewards. You rank flawless and pyrook to 5 and then sell them before getting the two commons to rank 5. Do you lose the ability to finish that chapter or do you forever get credit for having the monster once you obtain them at that required rank? IOW, does the game "remember" that you once had them and you get credit for once having them for purposes of book completion?

Is there ANY reason to keep uncommons? I've been playing the game for a year and a half and it's the only rarity that has never been used in a war or any other aspect of the game (other than book completion) in all that time.

As usual monster storage is an issue, and we are always trying to come up with any way possible to free up space without hurting ourselves.

Just sell then. The books don't change back. It'd be great if they did as you could keep getting the rewards by ranking an easy monster...

Your monster ranks will remain in your Monstergram based on how they last were and that is what the Library uses. So, you can sell them and if something appears later in a book, you'll be covered. I have been keeping some for war because every once in awhile they come up.

Every once in a while? It must be very once-in-a-while. I've played since April 2017 and they haven't been used once! LOL.

Thanks for the info, people. I'll get rid of the uncommons. Better to keep room for new legendaries than worthless uncommons.
