The little bit of discretion had been enough to draw Gil toward the crystal healer. The two easily hit it off when the crystal healer had begun to show how he was able to use the elemental crystals to heal. Walker had also watched carefully though.
The way that Gil channeled the elemental energy in to an arrow had some requirements. He had to have a place for the mana to go. It couldn't just be melded around the arrow and held there because it would just dissipate. It would also potentially cause the elemental crystals to shatter which was dangerous for everyone. That was why it was very common for the elven archers to have protection against such accidents when making arrows.
