Crystal Jams are upgradable items unique to Legendary Cookies. Similar to Magic Candies, they unlock a more powerful version of the Cookie's skill, and can be leveled up to increase the power of that skill, up to Lv.30 at maximum. However, they also possess unique additional buffs - a Rally Effect that grants an additional effect for the entire team, and Ascended Effects, a series of additional upgrades that are unlocked via the Cookie's Ascension levels.

Additionally, Crystal Jams may provide cinematic cutscenes of their corresponding Cookies when meeting certain conditions in battle.

Crystal Jams can only be used by Cookies of Lv.50 or higher, not including those enhanced by the Hall of Ancient Heroes.

Unique Effects[]

Rally Effects[]

Each Cookie's Crystal Jam can provide a unique Rally Effect to their team. In Team Settings, players can select any Cookie with a Crystal Jam to be their team's Leader by tapping the Select Leader button, applying their Rally Effect to the team. Only one Rally Effect can be active at a time.

Ascended Effects[]

Ascended effects are unlocked once a Crystal Jam reaches Lv.15. Each Crystal Jam has five different ascension effects, which only become active if the Cookie has reached the requisite Ascension level.

Crafting and Upgrading[]

Crystal Jam can be accessed from a Cookie's info screen. Upgrading a Crystal Jam requires Soul Essence, Sugar Crystals, and Resonant Ingredients. Each Cookie has a unique Resonant Ingredient required to craft and upgrade their Crystal Jam, and also requires one out of the three types of Sugar Crystals. At levels +10, +20, and +30, the Crystal Jam will also provide and upgrade a specific additional effect.

Similarly to Toppings and Magic Candies, the success rate of upgrading will decrease with each additional level. Failing an attempt will refund all Resonant Ingredients and some of the Soul Essence and Sugar Crystals spent, while increasing the next attempt's rate of success by 5%. Upgrading a Crystal Jam will also have a fixed 5% chance of Super Success, which if triggered will return back all Soul Essence and Sugar Crystals spent, gives 400 Crystals, and guarantee success for the next upgrade.
