First dungeon was the only dungeon I had to do multiple revisits (not counting revisits caused by forced leaves due to story/finding the treasure.)
My main strats were:
-Stockpiled on healing items and never used auto-heal to conserve SP.
-Only used spell attacks for enemies I haven't recruited yet, otherwise I'm using physical attacks.
-Maxed out Takemi's confidant to around a certain rank so I could get the SP Adhesive item (made dungeon 4 a cakewalk for me.)
-Stockpiled on the SP drinks from vending machines.
-Only supply I needed were lockpicks, and since you can make supplies/coffee right after sending the calling card, I would do that and grab any chests I missed.
Also, there were two instances where I was rank 9 with a couple characters when a new dungeon opened up, in which case I made sure to max those out first (I know I spent a little extra time maxing out a certain orange haired nerd.)
"Just for comparison Uncharted 4 was 20x bigger than Splatoon 2. This shows the huge difference between Sony's first-party games and Nintendo's first-party games."
