The Blast Sling is a medium-sized, handheld weapon with a sleek, futuristic design that combines organic curves with angular mechanical components. It features a central sling mechanism made of reinforced synthetic fibers, housed within a metallic frame that has a weathered, brushed finish with subtle blue energy accents. The weapon's surface is detailed with intricate engravings and small, glowing power nodes that indicate charge levels. Its proportions are balanced for quick handling, with a slightly elongated body that tapers towards the grip, ensuring ergonomic use during combat.
