The movement pushed the shaman from areas of low concentrations of Essence to areas of slightly higher concentrations. The dancing had a similar effect to what I did, which was to collect the unrefined Essence in an area and use that for incantations instead of personal Essence. I didn’t know why humans, Elves, and the like didn’t use this form of incantation. Either they didn’t know about it, or they thought it was primitive. Either way, I was just glad they limited themselves.
