Ratatoskr's Acorn is a small, intricately designed Norse artifact resembling a real acorn but with ornate metallic embellishments. The body is crafted from aged bronze with a slightly weathered finish, featuring delicate engravings of Norse runes and serpentine patterns that wrap around its surface. The cap is made of polished gold, contrasting with the bronze body, and has a subtle luminescent glow, hinting at its magical properties.
