The Daimos is not simply about summoning Ciphrang, perhaps we should look more closely at it's metaphysical attributes.
Something I noted from the glossary
"
elhusioli The daimos of excess. As per standard Kiunnat metaphysics, souls directly move other souls, impart the imprint of daimos upon another daimos. Some, such as terror or enthusiasm, are set apart for the dramatic nature of their effect."
It seems that there is both Daimos as sorcery, and daimos as a concept. The Ordeal seems to experience extremes of excess, terror and enthusiasm at various times. Does the intense emotional experiences of thousands and thousands of Ordealmen provide momentum for Kellhus or Ajokli?
Also I note the contrast with the extreme dispassion of the Dunyain, who seek to become self-moving souls
