Mortrex is the best and always will be.
Hmph, he cheated with medical miracles and I still beat his team of level 100 manamon with mostly high seventies.
SUX
More seriously though, it's nice to see consequences and lingering affects of a story long after it appears concluded. The implication that on some level, it continues on.
Nicely done.

Spoilers for 904
@904 I'm not sure if there's any points of interest as of yet. There isn't anything enormous in watery areas accept the hyper tarbu which is later on, but not sure if there's anything else.

Now a question.
Has anyone found any level up herbs? Like are there anywhere that I don't know about? I've only found a very select few.

I should ask for a refund just because of this horrible credit score. lmao. Well here comes post game stuff.
Would be hilarious if game crashed now.
Also, master arena tip: you can't use revival mists or any other type of mist inside of it. Found out the hard way after spending like 100k on revival mists. ROFL

@906
spoilers here. If you do not wish to know do not read.
Ok spoilers now.
So, you will need a water type manamon no matter what, at least one  level 65 manamon, and at least 5 to 6 stadium keys.
You go to shadow cannyon. You find the water that's northeast of the hotel. Swim east until you hit the wall. Go north, and you'll find a cave door thing leading east into submarine tunnel. Go south from here. You'll find a opening east, take it, and pick up a diver's gear.
Now this is why you need a water type. Equip this to your water type manamon. This will allow you to dive where water is super deep.
Now, you explore this area, look for a few gurgling sounding like things, and interact with them. You will be able to dive there if your water type has the diver gear equipped. You'll find yourself in this wierd underwater area. Go southeast, then you'll find a opening in the southeastern wall. Go east, and press enter until you are prompted for surfacing. Now go east when you surface, and you should find this island thing. Go there, and this guy will check for at least 5 or 6 stadium keys, and one level 65 manamon. If you have this, he will move aside, allowing you to pass. Go east, and you'll find another swimming area. Now, pay attention for the gurgling again, this time, save before interacting. This fight will take trial and error. All I'll say is that this hyper tarbu has about 7000 health, but some of those machines kill it slowly with you. I'll get you started by saying that it is important you kill the death cry machine first. It hits all your party and bad things happen if death cry elapses. When you kill this thing, make sure to grab the dark matter goo in that area which sounds like a normal item. Then surface, and go back to where ever you wanna go knowing you just obtained a goo for something.
Now that's how you reach hyper tarbu. That was more instruction than I expected to give, but there you go. Hope this helps someone.

One quick question. I'm obviously not close right now, but what is this new area hear Master Stadium with level 70 wild mons?

He just gave me a bunch of gold?
Yeah, there's nothing in the area beyond the manamon grinding spot and that one battle.
Also, thanks!

@914, go to the north of the map, keep going until you get on to that concrete that sounds like your kind of slide walking on it, and look for a door to the northwest of that. Then go northwest in the offices of doctor something and you'll find her there and can use her machine.

Righty spoiler question
So how do you defeat that wierd boss in the strange demention that you get to through the dragon's layer in requiem? I seem to get it to low hp, and then it detonates an explosive device instantly killing me. I'm not sure what to do here.

Cave of Fates Spoilers:
beyond this point,
your fate
is sealed
FOREVER
I really wish there was more context for this fight in the cave of fates. Unless there is and I'm somehow missing it? Whatever happened to keeping Alaza's promise lol
And what happened to the mythics?
Do you ever find out any of this?
How are you supposed to even know about the dark matter blades needing to be used against the guardian without knowing about the guardian's existence?

Does the cave of fate unlock after defeating the master manamon tamer? When I went there pre-victory I saw only solorbs floating around.

Yeah 921, you destroy those sollurbs, and you unlock this stone column thing you can climb.

I've thought about trying it because I eventually want to try all the ghost types, but capturing one is kind of obnoxious.
here there be
spoilers
Yeah I don't know why everyone's being so vague about this.
The black matter husks and the black matter goo can be taken to a guy across the water in the thunder prairie who says he's researching dark matter.
Once you've turn in the goo and husks, he'll make them for you. I'm not sure if there's more goo or husks, but it looks like 1 goo combines with three husks to make three dark matter blades.
The dark matter blades are equipment which you can give to a manamon and then they can damage the guardian thing.
Holding one is literally the only way to damage it. Even status stuff won't work without the blade.
Without a dragon or ice or whatever else is effective against dragon this fight is going to be a stupid slogfest.
In fact, probably even with one. Bring something with confusion; it helps, but only if you're lucky.
Once you manage to beat the boss--there's nothing fancy to it, just get a bunch of revives, leave half your party behind if you don't have enough dark blades for them all because otherwise they'll just get in the way when they're auto-released after resurrections, and spam the same attacks over and over until it finally dies--it will split into the three mythic things and fly around the world.
I'm not sure why they're terrified like the description says, and I don't know why you can walk in there even before beating the game, because I've found absolutely no substantial dialogue regarding the area. Not even Alaza talks to you about it. The closest thing is some house in the dragon gym area with guys who say "three stone manamon unique to the area" and "you're from this village where the cave is? Cool!" So obviously metagamely that's where the stone manamon are but...that looks like the only way to even be reminded of the area.
