Xbox 360 Speedrun Tips?

[Forerunner]

Ok, so I am only like, 3 achievements away from completing this game. One of the achievements I need is the speedrun achievement, but I keep missing the mark by like a good half hour or so. Has anyone here gotten this achievement, and if you have, do you have any tips on what the fastest route would be to complete this game?

The only way you can really do this is by completing the game and starting an EX play through. I've talked to another guy who told me he actually got that achievement on this third play through. What you have to do is buy the 10x experience perk from the grade shop as well as the item carry over perk. You essentially then just skip any random battles and run through as much as you can of the game including skipping dialog when you can.

Bringing Artes and Skills over from a previous play through would be nice too, but Holy Bottle is definitely your friend here.

Good luck.
