Hello, I've been told that Ecto is a good way to make money seeing as I'm a Necro........... What is Ecto? I know you get it in the UW, but how do I get it? is there a good guide anywhere on the internet? what kind of tactics should I use? I.E is MM a good tactic? Is it only worth doing it on hard mode?

I'm level 20 with a few good Necro skills.
Any answers would be greatly appreciated.
Edit: Sorry if this is in the wrong section
