So what is the must do during this next week, What poring drops should I save in my box, if I don't have the orb changes for the drop should I feed them to something specific, level them, or some other answer. The 2x should start tonight right? So I can feed these red knights and free up box space?
Almost all the answers there are dependent on your teams and where you're at in the game. But yes to the 2x and feed MFKs tomorrow.
Personally, I'd recommend prioritizing as follows:
1) Any descend you can reasonably low-stone run that you need the drop from
1a) Porings or MFKs on 2x drops
3) Poring expert if you need skillups for any of the heartbreakers
4) Super dragons/Pengdras/Jewels of colors you particularly need
5) MFK dungeon (move to 2 if you frequently run mono-red and haven't maxed one)
But then, that's just my take. Your results may vary. Skill-ups virtually guaranteed to result in dissapointment and regret. GungHo personally hates you, etc., etc.
Also, if you have no poison, get and keep a Ghostring. If you run Wed/Fri dungeon, you may want a couple more just to no-brainer runs in there. For other Porings, I'd personally just fuse for the XP. You can't level them other than Mastering, which I farmed one of and am working on skilling but it's more for novelty than awesomeness. I don't know that I'd sub them in as 11 turn low stat subs, Two Heroes wasn't really that brutal to run. Maybe keep a Drops because Valk is harder? I did, but never used it.
