Bagstone, the lovable Moderator, was asking about "Brainless Sage Builds" in this thread:
I'm using a variation of an old Sage/Tal Rasha Build with the Scoundrel follower, mainly because I've got a really good Wand of Woh (only item upgraded with Caldesann's Despair):
Bagstone then tested the builds and here's the results (videos embedded):
Apparently this build performed well from T8 thru T11, netting about 150 DBs in 12 minutes worth's of Rifting. Great for Keystone and Mats also.
