Rainbow Crystals

Rainbow Crystals are a currency in Cookie Run: OvenBreak. They are exclusively used to buy Costumes, cosmetics which give extra bonuses to Cookies. Rainbow Crystals are rare compared to other currencies, but as more costumes have been added, Crystals have become easier to obtain.

Obtaining Rainbow Crystals
Rainbow Crystals are uncommon due to the mostly optional nature of costumes. The only way to obtain them is to pull duplicate Costumes from the Costume Gacha, which requires Rainbow Cubes. Different duplicate Costumes produce different quantities of Rainbow Crystals. While Costumes bought through the Rainbow Crystal Shop are set at a consistent price, when a Costume is in Gacha rotation it will be priced at a lower quantity.

The only Costumes exempt from providing Rainbow Crystals are Champion Costumes- for they cannot be obtained more than once.
