Items are objects that serve as aid for the player throughout the game. They can be Drop Items, which are dropped and can be collected during the game, or Boosters, which are on purchase before the game starts, or Special Items for other specific purpose.

Coins (with those converted from Crystals), Trophies, Gems, and Boss Raid Energies are the only items that can be collected and be used for other purposes, aside from scoring points, such as Sidekick Egg purchase, Character upgrades, Boss Raid Energy refills, etc.
