Can someone explain me what this mean? Why are there so many of Mandalia Plains North, I only fight against the Monster in Mandalia Plains North 1 i think because I never fight against a black chocobo at Mandalia Plains. There are some different points you start at begin of fight but I dont know what all of this mean. I want to edit them and I am confused which I have to edit.

From each direction you enter a map there are 4 possible scenarios (plus chapter 4 special battles).  Also Some monster are randomly present and share the same x/y spot on the map this makes battles appear to be random.

Mandalia Plains North 1,2,3,4 the numbers stands for the chapter if I understand it right? because I never fight against a black chocobo in chapter 1 but I cant remember that I even fight there once outsite of chapter 1

QuoteMandalia Plains North 1,2,3,4 the numbers stands for the chapter if I understand it right?

No.  As I said they are all available as soon as you can enter the map from that particular direction.  They are not chapter specific. However, the "Special" battles are all opened in chapter 4. Ex: entd 069 Finath River East 5 or entd 05E Grog Hill South 5.

Actually Conman is only half right, those numbers don't EXACTLY correspond to the passing of Chapters (If I am correct, they actually might) but just significant events in game. You can't access every battle for a place once you can enter it from a specific direction. But the ones marked 5 are unlocked in CH4 that's for sure.
