Upgrade materials/Minnie Mouse Level Up Materials

Upgrade materials are vital objects in Disney Speedstorm that are required to level up Racers. First levels require Generic materials and/or Class specific materials but with the character progression more and more Collection materials are necessary. The materials cannot be interchanged, sold, refunded, replaced, and so on. Only when all necessary materials are collected, the Racer can be upgraded. Generic materials are applicable to all Racers while Class specific materials can only be used with certain Classes, and Collection materials are unique for each Collection (cartoon/movie). New materials are added each season due to a new Collection being introduced into the game. Materials can be bought in the Shop, received as rewards for Events, obtained as Free and/or Premium rewards in the Golden Pass, given for reaching a rank in Ranked Multiplayer or found in Mystery Boxes.
The maximum character level is capped according to the Star level (1 star characters can only level up to 15, 2 stars uncap level 25, and so on), and each new level increases character statistics. To level up Racers players use special materials. Some quests require a certain character level to participate, and the custom multiplayer mode has the option to cap the character level which means the Racers will automatically be downgraded to that level (if your Racer is level 20 but the cap in that mode is level 10, your Racer will only use half of their potential).
