This is probably the easiest character to play you will ever find, in fact you will never even be attacked again if you play it right. Turn on your Shadow Veil invisibility buff and walk calmly amongst your enemies, spamming Skeletal Fortresses to your heart's content, then sort through the mounds of loot at your leisure. It just doesn't get any easier than this!
This savegame is for a level 55 character just about to start Gold difficulty. As long as you keep the first three skills maxed, all the others are optional. Your main descision will be about the regen time of Skeleton Fortress. Pump runes to increase damage for large hits, or keep the regen short to spam multiple fortresses?
So go enjoy what may just be the deadliest mass killer in the game.
