Comments,
Definately not the best build in the world, can't handle every trap on elite but handles majority of them quite well, Battlewise against things that can be punctured is when he shines as not much stands up against the sheer amount of sneak attack + con damage.
Highish Ac and enough HP to not get 1 hit KO.
It's really the Equipment that makes him shine (having 2x Finnessible of elemental type greater banes helps heaps)
Decent enough UMD and can cater to almost every Situation
Take every potion/scroll that "could" come in handy one day and make sure your prepared for anything.
