Wolfe was looking at the stack of arrows in the room when he got a brilliant idea. These were made with Earth magic, and that wasn't part of his skills, but why couldn't he add a spell to the bow directly to create an arrow when the spell was activated?
He could make them out of the Elements that he did know, and while they wouldn't be the same as solid arrows made of Earth Magic, and they would dispel after they hit the target, it should work just as well.
That was a complex array since it would involve a minimum of five different spells to achieve the effect that he wanted, but Wolfe thought that it might be worth trying.
Eventually, the humans would go away, and that would mean that the local villages would need to fend for themselves using whatever they had managed to capture during the winter's invasion.
