buy 99 numstroms (dont correst my spelling) and put 15 of them on each character in your party (it would also be wise to have a lvl 7 tech on all of them if not at least two of them). When you go to attck him use only the basic 1 attack not the 3 attck (if you use 3 he will miss alot and if you have a 99 on a 3 use it but sometimes he will dodge it).He swaps what the main color element he is but make sure you do not use the same he choices or you will help him. Make sure your party is full of strong people or you will die quickly. Thats all i can remember right now if i think of anything else ill tell you.
