Okay, I tried to work out in my mind how a video guide should be done. The thing is, a simple map isn't sufficient to show you the direct path. As much of the mazes are blocks that appear over Bottomless Pits or invisible teleports, there is little good that maps would do w/o markers. And due to Random Encounters, filming myself walking the paths would be Awesome, but Impractical.
However, I can still give you some pointers:
-The first thing, before entering the obelisk from the front, enter from the back and get the Chakra Elixer. Remember that one item I said you'd need on the first page? Yeah, this is it. It restores magic too slowly to be game breaking, and its infinite use is a very useful safety net that you will want here.
-Bring a bunch of Light Balls and Float Balls. At least 10 of each, preferrably more. Also bring Chakra Drops and healing items. The reason for the latter is to keep you from running on empty when all you have to save with is an S-Terminal.
-There are 3 A-Terminals here, exploit all 3 for what they are worth. It may seem obvious, but overconfidence can sometimes cloud the obvious.
-If you are playing on Hard Mode and wish to keep a low level, bring a demon with Trafuri(sp?) and, if you can, some smoke balls. This was how I reached Baal Avatar at level 64 and Noah at level 62.
-Do not use the map on gamefaqs for floor 418, it is missing the exit path and will lead you in circles. While I don't recall where exactly it is, I do know that it is in the bottom left area (IIRC the map mistakenly marked it as a circled 7, but I can't remember, it is within that area though).
-Finally, don't panic if you see Mot, Aciel, or Surt, they have WAY lower hit point totals than their boss forms.
