Pure Vanilla Cookie is among one of the rarest characters in Cookie Run Kingdom. After acquiring him, you will come to learn that his healing powers are outweighed by a lengthy cooldown time, which halts his power from reaching its maximum potential. This can be countered by loading on X5 Swift Chocolate toppings, ingredients which drastically reduce the overall cooldown time.
Alternatively, you can add X5 Solid Almonds for toppings, which helps increase damage resistance. Considering Pure Vanilla Cookie is a support-oriented character, having such a perk can make a huge difference out on the battlefield. But then, you can always aim for a mixture of the two. For example, X3 Swift Chocolate and X2 Solid Almonds.
Either way, you should rely on a variation of the two toppings. Doing so will boost both your survivability in battle, as well as squelch the cooldown timer to help use abilities more frequently. Once the toppings have been added, the Ancient Heroes leader will stack up as one of the best pawns on the field.
