I understand I won't be able to heal in battle. Does anyone have a list of the icons I'll need to defend against?

Kumos Scythe: 2 ice, 2 water, 2-3 wind Vampire Bat Dagger: 6 dark, 3 wind Vampire Blood: 4 fire, 4-6 dark Kumos Skull Faceguard: 1 physical, 1 fire

Those are his weapons. You could just use Shinwas Helmet of Protection, and you'll probably win easily.
