Diamond (Dr. Mario World)

Diamonds are the premium currency in Dr. Mario World mainly used to summon new doctors, assistants, and single-use items. They can also be used to purchase more hearts if the player runs out, to give the player more capsules if they run out in a certain level, to give the player more time in challenge levels, or to start a level with a completely-filled skill meter. Diamonds are usually purchased via real money, though there are some instances in which Diamonds may be collected for free during gameplay.
