Feel free to ask regardless, sometimes it can take time to find. The wiki guide i linked should have most things you need.

I recommend checking the rank rewards by the way. At some point you get a platinum rogue so most other rogues won't be too important to level up. And at lvl 101 and some other levels you will get +1 stamina, and thus refill your stamina gauge. Remember that so you won't accidentally waste tons of stamina when you hit those levels
