Whats a good character that doesn't rely on items?

The Holy Shock Paladin is also quite well powered with no equip requirements

I will second this. My Pally is only level 75, and to act one hell, but he's doing fairly well without great equipment. I've had to go back and get my body while completely naked and been able to handle it by running around and letting my HS do the trick until I isolate a target or two and quickly punch them to death. ;)
