I forgot that, during my hunt for 30 Council yesterday, I stumbled across a level 31 Devouring Earth ambush that someone had left near the tram. 6 DE minions of various types, 2 lts. There was at least one each of tree-type, rock type, mushroom-type, and gem-type. They had already dropped a Tree of Life and one other emanator. I took them all out with the use of maybe 3 or 4 inspirations, in about a minute's time, with no real danger of dying, solo.
I had meant to add that into my earlier post, but forgot.
