-Sword of Switfness: Good and cheap (Not necessary though)
-Charcoal Shield: Fire shield
-Elemental Armor: Decent prot and element protect
-Wing Helmet: +1 air (Mirror Image)
-Earth Boots: +1 earth (Stone Skin)
There are boots, of Stone I think, that give the wearer Stoneskin.

-Bag of Winds: +1 air (now also Mistform)
-Blood Stone +1 earth (now Iron Skin)
Mistform is nice, but so is Pendant of Luck, and if you really want protection there are few options... But you could be using many different items too. That is quite a bit of research, though... If you can make up a strategy to survive up to that point, then it's a different thing!
