I'm a bit fond of the 'Firbolg Sniper with Vision's Foe and Eye of Aiming' combination, as a twisted joke, but that requires a rather diverse set of magics (nature for Awaken Sleeper, earth/death for Vision's foe, air for Eye if memory serves... and water, if you want boots of quickness for faster reloading) -- this was far easier to pull off before D3's restricted randoms.
