The earth proved to be the easiest yet again for Walker. A small spike easily rose from the ground with minimal mana from him. Next Walker held it and began to manipulate it like clay in to the form of the basic arrow that Gil held. All in all the fins were nearly exact when it came to comparison. The weight proved to be the issue. When Walker formed the arrow heads, he was compressing them to be sharper. Yet this was also causing the problem of making them heavier.
O know if it isn't heavy that they will fly straight. But if I don't condense the arrow head then they will not pierce something. I don't want you to hold an arrowhead that will just shatter when it hits anything slightly tougher." Walker was focusing on the form and making sure the shape was exact.
