Three

Three is earned by completing the Boneyard with a Mage cat. This unlocks the Three passive ability, which causes the first spell you cast each battle and every 3rd spell afterward to be cast twice. This effectively doubles the value of your most expensive or impactful spells if you time them correctly. Counting your casts carefully is key: plan your spell rotation so that your biggest damage or utility spells land on the doubled slots. Pairs exceptionally well with high-cost spells like Hyper Beam or any ability with powerful single-cast effects that benefit from being duplicated.
