Orbs drop like crazy it seems. Ex not so much but chaos and other orbs drop often. I just trade for ex when I can and so far (knock on wood) I have come out on top. It helps that some random dude gave me a small fortune for no reason so I had a great start.
It was awhile back but I needed armor scraps badly so I found a guy in trade that was selling some. No price listed just had hundreds of them. I messaged him in game and asked how much he wanted and this is how it went:
Me: "how much for the armor scraps?"
Him: "come"
Me: "I need armor scraps but how much do you want?"
Him: "Come."
(So I notice he is in his hideout and I go there)
Me: "Hi."
(Trade request pops up - I accept)
Me: " so what do you want for them?"
(the trade window fills up with several stacks of the armor scraps, 500 chaos, 40 Ex, and some random orbs)
Me: "whoa...I can't afford all that."
Him: "You take."
(at this point I realize English might not be is first language.)
Me: "Really? You are just giving me all this?"
Him: "I lots. Take."
(I accepted and he immediately left his hide out and then I did as well. and he booted me from party)
Me: "Wow man thanks that is awesome!"
(He never responded)
I'll never know why this guy did this. But he made things so much easier for me.
Have you discovered / used the Brotem yet? Combined with a curse on hit, that's an incredible way to stay alive as a ranged. (Skeletons with a Spell Totem) It also allows you to keep shooting, no interrupts to curse.
We talking the witch here? I do not use skeletons myself. Just zombies. Nor do I use totems for this build. I do use a curse on hit with my ranger to good effect. I tried skeletons earlier in the build but I prefer zeds as they do not have a duration. For my current witch build I do not need to worry about staying alive for the most part. Some bosses are challenging but so far my current build is blowing through most everything easily. I know I need to do more work on the build, mainly adding a couple of better armor pieces and improving some stats. I run a SRS build and it just dominates everything other than some bosses. Thats where having a friend or two comes in though. I run with a couple of friends and both can tank pretty well. Between the two or three of us we can kill bosses pretty quickly so far.
My marauder uses totems but that is the extent of my use of them at this point.
