After some time, Alaric looked at Kat and raised his sword. "How do I turn this off?" The link between him and the formation had been transferred to the spell still active on the sword.
"Just imagine it going off and it'll naturally do so," Kat said. "Or just cut off the flow of arcane into the spell, cutting off the flow is much better."
Alaric held the link with his mind, it felt to him like a rope, thin yet strong that transferred arcane from his core to the spell. He thought of the arcane pumping into it to slow down and immediately the thick grey covering the sword lessened until only a whisp remained.
"Well? Aren't you going to practice with it?" Cook asked with a glint in his eyes.
Alaric increased the arcane and his sword flared with grey again. "But why is it covering the sword? I thought it would...I don't know shoot something out."
