All the hieroglyphs in the sacrifices are only a means of aiding memory. The original intention is to allow the caster to recall the large number of details and steps when casting spells. In that era, the greatest mages were those with the highest talent for memory. However, magical invocation was too difficult, so all mages had to specialize. Even the most diligent mage, who devotes his life to magic, can only master three or four spells at most. Ordinary mages are satisfied if they can master two, but for those rural mages, it is normal to only master one spell.
