Well some people are of a mind that it is a hit or miss proposition in the UW. Either you ARE good enough to kill the nightmares or you're not.
Me personally, I'm not quick enough to kill the Nightmares with thier new Rend Enchants buff. I never really considered going into the FoW with this build. I guess shards can make up for ectos to make money.
NP. I read so many links at once I never bother to see when the last post was made.
No matter what. There is no solo build that will do better than a dual run with an SS necro. That said, I think the last time I used the build pre-nerf was around 55min.
The ele one is. It takes ten minutes to finish a run, but it's hard to start off, at least for me. I can kill the graspings but they usually interupt me. And when they do that I mess up, hard.
