Absolutely agree with the description! Only one way to kill him with low level character without cheese is roll catch or you can use cheese like Ash of War: Lifesteal Fist (or Inescapable Frenzy incantation) that continuously grab him to the death. Horn incantation also does not give him do anything. If you can do good timing, Ash of War: Stamp (Upward Cut) also can help you kill the All-Knowing.
