Limited-Time Mini Candy Boost

Mini Candy Boost uses fewer Dream Shards than the regular Candy Boost function, so this limited-time function can be easily used even by researchers who just began playing Pokémon Sleep.

Using Mini Candy Boost lets your helper Pokémon get twice the usual amount of EXP from candies in exchange for using four times the usual amount of Dream Shards per candy. This function can be used with up to 50 candies per day.

This function will be set to ON by default. You can freely toggle this function ON or OFF by tapping the button in the upper right of the Level Up screen. Feel free to use Mini Candy Boost when you want to level up your helper Pokémon!
