I really want to get at least 4 etheric light before the taken king comes out. I really want to ascend my new monarchy head and be able to be 34 in more than one set of armor. I really don't have the skill to go flawless, I have never done skolas (and probably won't because I don't have a Ghorn), and the only things I can think of are nightfall and iron banner. Is there any quick way to get etheric light or are the ways I mentioned the only ways? Thanks.
