I boosted an Astrologian to 60 a while back, and now I'm trying to boost a Scholar. However, when I try to use the new boost item, I get an error message saying "Unable to use the copy of tales of adventure" because I have a duplicate item. I'm assuming this is because pieces of the boosted Astrologian gear match with the boosted Scholar gear, and they are unique.
Should I toss the duplicate gear to make it work? I'm just a little hesitant to do so in case I was supposed to do something else.
Thanks in advance!
