OK. What I'll do later on is make the Beas't next 3 times bigger, and it will have sort of a spiral like this:
*M****X**
* * B***
******* **
** * ** *
A ** *
*********
So you'll go enter from Alghetty(A), then go nw, sw, e, nw, n all the way to B which will be open from east to west during the Mt. Woe part. You will keep going all the way to M, where you fight the Mud Imp, Frost, and Flame Beasts. Oh yeah, you'll fight Beasts all the way through the winding areas.
When you come back when this map is submerged. B, will go north to X, which takes you to the Sunken Zeal areas.
When I get that far, you will have increments of 4 minutes to find pockets/rooms of air. Failure to do so will result in death.
Also, there will be underwater battles in the Beast's Nest and Zeal. I know there are Blue Imps riding Octopods but they are currently glitched. If I can fix them, I can make them have Tsunami moves and such. The Kraken will also be down here. I just need to make one more enemy down here so that it doesn't get repetetive. I am not sure what though... Maybe Heckrans with scaled up stats? They love water I know that much.
