Hello!

I can't check the names of the scroll right now but if you want to open the important ones or the one with better stats, those are the 4th and 7th plates. Thank you.

Hmm.

It is either you keep your materials for now and wait for the other Plates that have better stats or take the other ones now just for Initiative. Personally, I'd open it all and upgrade them to a safe level only since all of them give Initiative, and that would be at Lv8 to Lv10.
