The Bone Digger Sigil is a sinister, hand-drawn emblem with a dark, pixel-art aesthetic, featuring a skeletal hand emerging from the ground, clutching a pile of bones. The design is asymmetrical, with jagged, uneven lines that give it a rough, textured appearance. The color palette is muted, primarily consisting of dark browns and blacks, with subtle hints of eerie green luminescence to highlight the magical nature of the sigil.
