Raven Frost is a unique ring in Diablo IV, featuring a dark, metallic band with intricate engravings of raven feathers and frost patterns. The centerpiece is a glowing, icy-blue gemstone that emits a faint mist, symbolizing its frost-based properties. The ring's surface has a slightly rough texture, giving it an ancient, mystical appearance, while the gem is smooth and polished, contrasting with the band's weathered look.
