The sling pellet gleams like polished obsidian, etched with faint, swirling runes that pulse faintly under torchlight. Its surface is unnaturally cool and smooth, heavier than lead, with a subtle iridescent sheen that hints at trapped starlight. When loosed, it whistles through the air, trailing a comet's tail of shimmering dust that erupts into blinding white fire on impact, searing retinas with unrelenting glare.
