The Armlet of Mordiggian is a powerful, semi-realistic fantasy artifact with a dark, menacing aura. It features a central, ornate blood-red gem encased in twisted, gothic metalwork that resembles skeletal fingers clutching the gem. The metal is dark iron with a slightly weathered finish, showing faint engravings of ancient, forbidden texts. The armlet's design is asymmetrical, with one side extending into sharp, claw-like protrusions, suggesting its cursed nature. When activated, the gem pulses with a sinister glow, and the metal parts seem to tighten around the wearer's arm, as if alive.
