Well, it went better than expected. The lack of the 2nd valk hurted a little during Monster Extermination H, but still managed to clear it with 1 star (f*ck u plat armors, lol) and get my first Odette.
40 mins until I can give the next stage a try, though from what I saw in videos, it may be kinda tricky for my current team, so I'm already using available time to improve it.

Let's see how it goes. Worst case scenario, I'll have to farm stuff at Monster Extermination H, instead of X.
