Roblox WikiGems
Developer product descriptions associate Gems with summoning at the treasure chest and with evolutions. They do not provide a complete evolution cost table. [2]
Trait Crystals
Trait Crystal product descriptions place hero trait rerolls at Castle Lemongrab. Trait rerolls are distinct from the stat-grade rerolls described for Juice. [2]
Juice
Units of Juice are described as rerolling a hero’s stat grades in the Reconditioning Chamber. The source does not list the possible grades or their probabilities. [2]
Enchiridion Pages
Enchiridion Page descriptions say evolutions at the Enchiridion Shrine require Pages. The number required for each hero is not given. [2]
Summon modifiers
Lucky Summons advertises twice the Mythic odds and 1.5 times the Legendary odds. These are multipliers; the base probabilities are not supplied. [3]
Hero capacity
Big Backpack advertises doubling hero capacity. The catalog does not give the unmodified capacity. [3]
Match rewards
The 2x Gems pass covers wins, challenges and Infinite waves. The separate 2x Drops pass covers match items such as evolution materials, Trait Crystals, Enchiridion Pages and XP candies. [3]
