T6 essences

Hi. Can anyone help me with T6 essences in necro settlers? Not sure how to go about it. Not sure what essences i should be targeting and all as when I look at currency exchange they aren't worth much chaos (with how much chaos is worth 1 divine now)

Are you wanting advice on how to farm them? Which ones you get are completely random. Zizaran has several videos out for farming, but that is most profitable early league when essences are coveted. In general, map tier and map modifiers do not affect your essences, so you run the hardest difficulty you can without sacrificing any speed. Keep a stack of corrupted essences on you and corrupt anything good. You'll want to pick a small, relatively linear map.

Even when not farming essences I still keep corrupted essences on me and corrupt anything with a purple essence in it.
