- Save your Monday's ex roulette, and use it on Tuesday after reset. So now you have 2 sets of roulette to do. (I wouldn't worry about trial roulette that much)
- Get in Alex normal floor 1-4 and grind til you got all the loots.
- After that, grind fractal/neverreap til you maxed out.
- While waiting for duty, you could also do the daily centurio mark hunt.
- As other has mention, you could also do frontline as well(can save the Monday's portion of frontline roulette)

That's what I did today since I will be away for a whole week since tomorrow, lol.
