I used to have a smiter that did uber tristram solo in under a minute. Found this bad ass zakarum shield with 45 res that I glitched and made a 1500 defense exile with it.
Used a heavens light with 15ias 15 all res jewels. Same jewel in my guillames.
Raven and dwarf star rings with a highlords amulet. Tgods belt. Gore rider boots. Cant remember what gloves though.
Ofcourse I only found a few of those items myself. Traded for most of it and duped the runes and jewels.
Oh and I used Duress armor instead of Coh.
Ofcourse this character was made for a very specific purpose.
I still say the best all around build in the game is a lightning sorceress with infinity on your merc.
