Witcher Dice Set. Yennefer - The Obsidian Star Focus on the star. Inspired by The Witcher franchise, this dice set is dedicated to Yennefer of Vengerberg — the raven-haired bearer of the Obsidian Star. The set contains 8 pieces; 7 polyhedral dice, and a metal coin featuring Yennefer's depiction, which acts as a D2. Each die is painted black with silver engravings. The highest value faces and coin reverse share imagery with Yen's pendant. The Witcher Dice Set is officially licensed by CD PROJEKT RED.
