There's aot of ways you can upgrade weapons. Buy science item from the store with dragon scales or purchase a graded sword with maybe lesser cost since u already have a B-rank one.There isn't a way to upgrade swords right? (Like turning the B-Rank sword I get from Camelot to an A-Rank via some shop purchases)
Also, how can I earn 5,000,000 Beri quickly? I am about that much short of buying Awakening and still being level 80 with the next round of activity....
For the 5M weekly, 8 guess you already earn more than that with Doffy's defeat.
