Yeah but I can just leave it on while I am at work and while I sleep(which is what I am doing). I am tweaking the Gambits because sometimes my party leader still kicks the bucket and no one revives him/her in time.

But the exp required to get to level 99 is insane. In the guide it says that to gain the 10 levels between 90-99 is over 4 million. The guy estimates that exp gained per hour doing this trick is 100K with out the double exp thing.

My only problem so far has been my party leader not getting revived in time...also I took me a while to get that guy to appear and for me he was not even visible until he just magically appeared when I got in range so I guess you could say he is kind of like the snakes. You can't see them in the grass until you get close enough and then they come out.

And yes it is the Stillshrine of Mirian.

I would not recommend do this until the part of the story where you go to the Feywood. Just because of armor and weapon strength.
