If you'd like a different way to get the hard badge than the one given by tiri23, try this very deadly method. 1. spend points on 1/1 smite, 2/3 holy grace, 3/3 justice, 2/2 swift retribution, 3/3 holy wrath, 2/2 chosen one, 1/1 ice bolt, 2/3 winter's might, 2/3 frostbite, 3/3 ice bolt frenzy, 2/2 glacial flow, 2/2 chilling winds and 3/3 master of the cold. if you do this, you can end up with smite and ice bolt going off at once, with mana NEARLY keeping up with it (+100% mana regeneration). I made it to 655 first try on survival, you should end with 15 in ice tree and 13 in divine, equip icebolt, smite and healing spark, Vote up to keep this comment alive.
just a quick suggestion... maybe have a junk shop that would sell stuff you binned, there's a lot of things that if you accendently delete, you can't get it back... or perhaps have deleted items go in the item storage?
