Thanks for the help peeps, nice idea with the Immunity Alteration to get over the teleport field...
However, I would dispute that the ring of the ram works, because I tried this several times in my battle to no avail.
Reading the readme revealed "Kensai Ryu added a bunch of spells to Kangaxx and gave him the option to work around some common used tactics that kill him."
I think this means the ring
Cheers once again mates.
