Bull of Heaven
The goddess Inanna (also known as Ishtar) once sent an enchanted bull to kill the hero Gilgamesh. To grant the bull supernatural power, she bathed it in precious oils and coupled with it. An ashipu can similarly enchant any animal (not just bulls), although instead of sex he bites the animal while feeding it some of his own vitae. The animal not only gains a ghoul's strength, the magician gains a psychic link to the animal for the rest of the night.
System: The animal becomes a normal ghoul, with one dot of Potence and one dot of another Discipline (either Fortitude or one possessed by the magician at the magician's option (though no animal is wise enough to Dominate its foe or cast a Thaumaturgical ritual upon it, for example). For the rest of the night, the magician can use the animal's senses and direct its actions whenever she wants. This ritual's effect resembles the Animalism power Subsume the Spirit, but has much less power.
