The Deathcard Key is a sinister, intricately designed key with a blade shaped like a skeletal finger, complete with jagged, bone-like ridges and a weathered, tarnished metal finish. The bow of the key features a small, eerie skull motif with hollow eye sockets that seem to glow faintly in the dark, adding to its ominous presence. The overall design is asymmetrical, with a rough, hand-forged texture that suggests it was crafted in haste for a dark purpose.
