Wow, kinda hard to believe it's been a whole 4 episodes since we got a sticker.
Anyway, the guide's been updated for episode 18! A new sticker, a raise in price for repels, and battle items have been pushed back to floor 8 due to becoming OP in Gen 7. That last part might have been a thing in episode 17 and I missed it, but whatever.
Spoiler warning as always, but you probably should have guessed there'd be spoilers in a guide to a "sidequest" that spans the entire length of the game.
