Yeah, I was clear on the skills/activities, and how those all work. I was more concerned with leaving enough time to complete the dungeon, and when I should actually start one. I figured it was a one and done kind of deal. I didn't get the scope of these dungeons. I just played for a bit, and hopped into the palace. I get it now. The dungeons are huge, and Ideally are meant to be tackled sporadically throughout the month. Three floors here, three floors there, in between building up your other skills in the real world. You go as far as you can in the palace, until you run out of shit, head out, stock up, and go back to where you left off the next day, or whenever, get a little further, and repeat.
It's all clicking now, and I'm hooked. I just hope I left enough time. I had 6 days when I entered the palace, and I'm on the 4th floor. I think I can go maybe one more floor before I have to burn a day, and go back to get restocked. I'm running low on bullets, and my SP won't be far behind it. It's gonna be tight.
Thanks for the other tips as well.
