Easily fixed. One of your GF's has an ability called "no-encounter" turn it on and fly your ragnarok to the island closest to heaven or hell. Now run around the outskirts of the island and through the middle, and keep pressing the action button. You'll find a few dozen draw points with all the best magics in them. When you have used them all, fly to the other island (heaven or hell) and do the same.

Repeat until you have a huge supply of all the available magics. Now go to your junction screen. Select "magic" junction and scroll down to one of your stats. Select strength and scroll through your magics until you find ultima and press the action button to confirm your choice. Now your strength will be sky high. Now do the same for your other stats. For speed, attach 100 triples. For vigor, attach 100 meltdowns (you can refine these heavily from items) for HP attach full-life's, and use flare's and holy's elsewhere.

Kinda cheap but it should solve your problem. Your speed will be at least treble what it was, your hp should easily be around late 9000's, and your strength will hopefully be max. Have fun
