A charm to gain advantage of a man of superior strength:

I [name] breathe upon thee. Three drops of blood I take from thee: the first out of thy heart, the other out of thy liver, and the third out of thy vital powers: and in this I deprive thee of thy strength and manliness.

Hbbi Massa danti Lantien. I. I. I.
