Black Sapphire Cookie was introduced to Cookie Run: Kingdom in February 2025 after appearing on loading screens and in promotional material. You can learn more about him in the newest addition to Beast-Yeast, episode eight. Together with Shadow Milk and Candy Apple Cookie, he is part of the “Deceitful Trio.”

This addition to Cookie Run: Kingdom is a support cookie that defaults to the middle of the team. Though there are better choices for healing and support cookies alone, Black Sapphire is worth investing in, or at least obtaining, for game modes focusing on team composition and/or elemental damage. So, how should you build the final deceitful cookie to its fullest potential?

Like most support and healer cookies, Black Sapphire Cookie benefits the most from chocolate toppings. Though regular Swift chocolate toppings will work just as well, he can also use deceitful toppings. This will allow him to continuously heal and buff the team. Though he does deal with some damage, he doesn’t consistently do enough by himself to make other toppings like searing raspberries worth using. It's much better to allow him to stack up his poison effect.
