Hey another question on top of the ones in @51. Should I explore the fake world more before destroying the two machines? I don't want to miss anything. It'll be a real slog to go through all of those traps again but I haven't fully explored the castle or catacombs. I at least need to do some grinding before the hyper Hathorilion fight.

That's what I was thinking. I just wanted to make sure I wouldn't lose the opportunity to explore the rest of the world. I took a crack at Hyper Hathorilian and I came close but lost. That chaos chamber move is the worst. I'm hoping to train some of my weaker team up enough to do the fight since Plant Apocalypse wrecks my starter.

Confusion works, but you are going to want all your manamon to do considerable damage for several hits at a time, especially considering you have no choice but to go through all four fights in a row.

If you destroy the machines first before grinding, you can go back and forth through that hold in the edge of the world that is created once Requia starts to fall apart. You are not time whatsoever, and the plot doesn't continue until you step past those machines.
Also, try to make it through the Hathorilian fight without using the crystal. If you manage that, then you can use the crystal during the fight with Chaos Ogma to make it an absolute pushover. Don't foget to actually use it though, because I do believe that once Requia self-destructs you can't use the crystal again. Makes sense anyway since it was meant as a last resort during the final showdowns anyhow.
Also don't worry about missing anything right now at least. In Tradail Village there is a time machine that will allow you to revisit Requia, where you can revisit any of the areas. There's a little surprise once you're the manamon master as well. You do not, absolutely do not want to go back into the Edge of the World, because you cannot go through the door leading to the machine and the final fight. It's a bit hard for Hathorilian and Ogma to fight when they aren't around and, so that area is dictated by the classic never screw with time trope.

hi again everyone, How please in the 2nd stadium do i pass the force field s p o i l e r I like the boats but when get across the water, i hear the switch but cannot seem to get to it? marlavont is the shadow type i am seeking does he do the unending curse? also, can i do the stadium before go to madam bovells and the rest of the area?

Hey Accman!!!!

Did you finish the fourth Stadiums? When you finish the fourth Stadium. And then go back outside and go all the way to the east. There's the guy will give you the rope.

An important thing to note is that this game likes to make you backtrack. The demo is actually quite extensive, but you're going to find a lot of things (water, ice, climbable trees and such) that you can't interact with yet. This doesn't necessarily mean that you missed anything; it simply means that Aaron wants you to come back later. You are not intended to get the coins on your first pass through the city. Using the search feature, however, would've shown you where all eight coins were, and hopefully let you deduce this, since one coin would have been in an area you can't access yet.

The search feature helps explain Barren Underground a little bit. It's not extremely detailed, but if you can't get past the doors, it means you haven't found the keys. I wrote an extremely bare-bones explanation of this area which should show up there if you use those search terms.

Um, no. You probably could've found that out with the search feature.
You progress across the ice preserve way, way later, as in, after the Requia plot is over, for obvious reasons.
Also, if you were paying attention, you would've noticed that the captain takes you to Shaddow Canyon. That's got nothing to do with the ice preserve.
That being said, you will actually want to go baack to the ice preserve in a bit as there is something pretty helpful there that you otherwise would not have gotten to.
