What should be first?

Hey fellow Mazey-ers!
              It's been more than a month since I started and I barely have progress in this game
              I really need a Pro's Suggestion on what I should do to be strong. I have an elementor with sea king cloak and Donate Fashion and is mainly for farming RPs. I have a Harlequin which is I what I want to be my main character and a blade which I want it to be for Boss Hunting. I'm confused on which character I should farm on for. Should I farm for FD Blade pack first or FD YJ pack so I can hunt bosses faster.

              What should I doooo? I really wanna join GS so bad but I can't seem to think how to farm for my Harlequin fast. Through BH or through RP farm?  :3

              Any Suggestions? Sorry for my english

What should I farm for? For Slayer or for YJ?

Make a slayer first so that it can farm Colo and possibly help you get enough money saved to then make a good YJ later ^^
