Perhaps I'm missing something, but the only conclusions' I got to were: 1) pray the advies find more scrolls and 2) send our armies at the daimons to try to kill/capture as many of them as possible.
For example, Overlord said that we should all understand how the blight works by now. However, as a ruler, I've seen most of the messages going around, and I have no clue how the blight works, other than the obvious that takeovers usually allow them. Portal stones can blight a region, but they aren't needed to blight a region, so I'm not sure if they have another use than that.
