Hi annis

I hope you can help me a bit. I noticed, that the auras from thunderfury and nephalem ammy do stack. But they dont further stack if i equip a dreamshield additionally. (My screendamage stays the same)

What exactly makes the auras stack or denied it?

Would 2 thunderfurys + nephalem stack? A dualwield barb with lvl 75 unsynergied holy shocl probably would outperform a lvl 45 synergied holy shock zealer pala, hm?
At least it would be more fun as barb i think...

Tell me plx ty!
