“Nine nights I hung on the bare tree, my side pierced with a spear's point. I swayed and blew in the cold winds and hot winds, without food, without water, a sacrifice of myself to myself, and the worlds opened to me.
'For a tenth charm, I learned to dispel witches, to spin them around in the skies so that they will never find their way back to their own doors again.
'An eleventh: if I sing it when a battle rages it can take warriors through the tumult unscathed and unhurt, and bring them safely back to their hearth and their home.
'A twelfth charm I know: if I see a hanged man I can bring him down from the gallows to whisper to us all he remembers.
' A thirteenth: if I sprinkle water on a child's head, that child will not fall in battle.
'A fourteenth: I know the names of all the gods. Every damned one of them.
'A fifteenth: I have a dream of power, of glory, and of wisdom, and I can make people believe my dreams.'
His voice was so low now that Shadow had to strain to hear it over the plane's engine noise.
'A sixteenth charm I know: if I need love I can turn the mind and heart of any woman.
'A seventeenth, that no woman I want will ever want another.
'And I know an eighteenth charm, and that charm is the greatest of all, and that charm I can tell to no man, for a secret that no one knows but you is the most powerful secret there can ever be.”
