Using "Silvermoon Slash" didn't require Spellcasting Materials; one only needed to use their limbs to draw a Light Trace in the air. The silver Light Trace could be brought down with a slash, thereby unleashing its attack form.
Before midnight, Shard had tried many times in his room with the curtains drawn, creating traces of light and then making them slash forward. He was extremely excited. Although he had tried Telekinesis, Echo of Blood, and Light Spell before, "Silvermoon Slash" truly matched his vision of "power" and "mystery."
Unfortunately, Shard was only a beginner and his understanding of the "Silvermoon" Elemental Rune was shallow, and his Spirit was weak. As a result, those Light Traces could not even leave obvious marks on the walls.
But if it were merely to harm the fragile human body, close-range strikes would probably suffice.
