I see something I want on the market board and start doing roulettes as a tank to get the extra gil and those cracked clusters and trade them in for materia. Then I transmute them and hope to get crafting and/or gathering materia. When I do I sell that materia on the market board. Eventually I get enough money to buy the thing I want. Then I lose all of the money I got to buy that thing. But it’s okay! I have a bunch of allagan pieces on one of my retainers. So..... Technically I’m not a rich player.
