Question on Tyrian Missions

I heard about a year or so ago that you could go through missions again and acess certain areas that were other wise unavailable on my first play through. Is this true? I'm askng this becuase I'm trying to get my Map to 100%.(75.5% now)

Well i know you can miss things in the magumma jungle because they didnt require you to do the mission, maybe thats what your thinking of?

Things that were unavailable in missions about a year ago?
Can't think of any.

However, in the missions, there are areas where you usually don't walk when doing the missions.
An area behind the bonus boss in Aurora Glade, the bonus area of Dunes of Despair and the back-end of The Wilds mission (together with the area above the bonus bosses), upper and west part of The Great Northern Wall are some.


Furtermore, there might have been limitations because you could not use skills like Necrotic Traversal to access some areas, because you had no primary or secundary Necro.

That's the only thing I can think about and yes, you need most of those areas for 100% exploration.

Well i know I need those areas xD
Also, I'm doing the first mission in proh and there are so many pats I missed runing away from the char xD
This is my second run through. DAMN YOU THREE MINUTE TIME LIMIT!
