In the first couple hours of Final Fantasy XIV you’re presented with the Duty Roulette system. This is the main “daily mission” system of the game, in which you’re randomly matched into duties depending on which Roulette you choose (Leveling puts you in leveling duties, Trial gets you on Trials, and so on). You get some bonus Gil and Experience for doing so, making them the best way of leveling your jobs.
Among them, we find the Expert Roulette, which might not grant experience, but nets you tons of equally important currencies. This Level 90-only roulette is not initially available, and here’s what you need to do in order to unlock it in FFXIV.
