Well im not sure if you fight Volvidon before or after but, if you can get a Volvidon armor set it would be great.

Skills: Attack Up (S), Evasion+1, Tremor Res, Cold Surge

And it has good fire resistance. It might help.

You will need a good ice weapon and water weapon. Ice is Diabloses weakness as water is Agnaktors and Uragaans.

Try getting the Tusk Lance (Barioths lance) if you can because it is suitable is your good with it. Maybe try the Frozen Core (hammer) for Uragaan. Im not sure what for Agnaktor though. Hope this helps. :)
