I wanna do it, but I can't find the guide for it (because I just need to papss it once and I've already seen it.....so yeah

What about the dungeon do you need the guide for?
The Puzzles?
Actually fighting the bosses?

....the puzzle mainly....i think i can handle the boss with my lvl 60 parties

Well, the puzzles aren't mandatory to fight the final boss, but each one does lock its own boss behind it.

the runes one is based on the Sylestian weather (not quite the way you'd expect, as in "ah it is snowing, I will use the cool rune" would, in fact, be an incorrect guess. It's just down to how the runes classify them. If you want the exact ones we can say?)

Sliding puzzle is a sliding puzzle.

the number-lock is the one you have to be paying attention for- throughout the dungeon sometimes there will be an event where you just come across something like "there are x number of chests in the room, but they're all empty" or "there is a carving of y number of zolnixi". Write down the number, for a total of three numbers. This is your randomised number-lock code of the day.

thanks!

just in case they're needed we'll write the rune answers in Spoilers Colour that you can highlight between the v^'s
v
Warm = Clear
Cool = cloudy
Air = windy
Wet = precipitation of some kind, eg. rain/snow
Shock = storm
