So, I'm down to two challenges left in the current season chapter I am working on: T12 nephalem in 6 minutes and completing one conquest.
I can clear t12 comfortably (apart from the occasional instagib when I take a hit with my defenses down) but not that fast. I had an ancient fury of the vanished peak drop, so I was trying to put together a build to do the conquest completing a Gr45 with no set items. I was getting fairly close to that being possible I think, and I just had an eventful session...
A magefist dropped for me, which is great, because I had cubed the only one I had found and needed to use the cube armor slot for cindercoat.
Then, I ran over to the cube to upgrade a couple of 2h mighty weapons (how I got the FVP I mentioned above) and lo and behold, out pops an ancient blade of the tribes. Not a good roll across the board (low strength, no life on hit or fury, no vitality) but 200% earthquake damage. In a way, the worst part was that it rolled with a slot. Normally that would be good, but because I have a ramaldni, I had to roll the socket off. I got a high vitality roll on my first shot, so am keeping that for the moment (can't really afford to give up 1k vitality rom my old one).
At any rate, I'm thinking I can do the conquest now using this instead, along with magefist and an Andariel's visage with fire damage boost and convection of elements, and my girdle of giants.
Still don't think I can do the T12 in 6 minutes, but should be closer.
