The best armor would be karil's, the best weapon in my opinion is the zamorakian spear because it's twice the speed of a godsword with a more powerful crush attack than the saradomin sword. Other than that I'd bring super strength pots (I don't bother potting attack), 3-4 bunyip pouches and about 100 (just to be safe) swallow whole scrolls along with about 2 summoning potions. With a bunyip I ususally fill the rest of my inventory (save spaces for charms) with sharks/monks. Obviously the sure-fire way to camp fiends is with a unicorn.
