Prism Strike

Morning rays hit the yard, and my shiny amber marble was begging for a tactical test. I rolled the heavy glass sphere onto an upturned slate shard along the path. Pure elemental lens. Lining up my katana, I adjusted the angle until sunlight focused through the sphere into a blinding beam straight onto a dried weed stalk. Smoke sizzled! A tiny black crater burned into the stem in three seconds flat. The perimeter is fortified, and my solar strike canon is officially operational.
