Not sure if this is build is novel or not, couldn’t find one like it on the forums but I admittedly put all of 10 minutes into searching. Anywho, Cabalist focused on Vit damage utilizing Drain Essence and Ravenous Earth. I am at the end of Elite currently and have been plowing through the game and fighting mobs 6 levels higher than me. Only real hazardous times come when facing a mob that deals spike damage - like the big trolls with the giant clubs - otherwise with HP drain you can just stand there and nuke till the cows come home.
Build:http://www.grimtools.com/calc/mN4DA3BN - shown with some items I assume will be BiS, but can be ignored. As I said, I am currently playing this largely self-found and am doing just fine.
+super easy to gear (only one piece I’d say is a must have, and its a green dagger http://www.grimtools.com/db/items/2074)
- kills super fast
- above average survivability
- spike damage can kill you if you aren’t careful
- mana intensive
However, that list of negatives may expand as I progress in difficulty. Eager to see what happens in Ultimate.
I’ll be adding more as it progresses and like I said if this is already done or if it is a copy of some well known build then I apologize for my ignorance.
