ok open up your reports and look at your arena scores it should show you if anythings missing.....DO IT NOW!
you have no idea i had to give up, i got gamer rage to the point i almost broke my psp, so i switched to terra and used the ROOOOOOOOOOOOOOOOOOOOOOOOOOOOCK (XD) to beat VR at 38 XD and then i used the void gear and beat his mirage arena today.
well true i prefer mega flare for room clearing, you can go thru rounds in the arena like nothing XD
a combo i like is to use magnera then something like windcutte (terra) or faith/tornado (ven)
