Transmission.
It is a method of transmitting mana in an object or a model, which leads to transfiguration. An earth magician can transmit his mana to a stone, and the stone will transform into something the magician desires, but only possible with the amount of energy the stone receives. It also applies to scale models or a scheme. As long as one is capable enough to create a configuration of their desired plan, then with the transmission, the transfiguration will commence.
