I finally beat him!!!
I had a lucky
robots foot equipped but didn't actually need it.
Since the lab ray turned me into a faerie Kau today, I bought a Kau Knights Helmet and used it with a Florbix Blaster.
I used Drain Life on Turn 1, Then Sink, Then Burrow, then Fierce Attck every turn after that. He used his scorchstone twice but I eventually beat him
Thanks for all the help Chao & Matchbow
