Extreme hypnotism induced by spoken words seems quite overpowered, especially in the political landscape of this world. This magic seems to directly influence the senses of the affected, so just to understand it, can Tanis squirt some water at anyones face, tell them its a poison that destroys vision then convince them that they are blind? Also, is it right to assume illusions and dreamwalking cant physically hurt anyone directly nor cause changes to the real environment?
