Mobile Legends: Bang Bang Diamonds is the in-game currency that can be used to purchase various items and features within the game. Diamonds can be obtained through in-game purchases using real money, or by participating in various in-game events and completing certain tasks. They can also be obtained as a reward from events, tournaments, and giveaways organized by the game developers. Diamonds can be used to purchase a variety of in-game items such as heroes, skins, emotes, and other cosmetic items. They can also be used to purchase certain in-game features like hero trial cards and battle points (BP) conversion.
Additionally, Diamonds can be used to purchase skins for heroes, emotes, and even converted into BP. They can also be purchased in bulk, usually at a discounted price, in the form of bundles or packages. It's worth noting that the availability and cost of these items and features may vary depending on the region or country you are in. While Diamonds can enhance your gaming experience, it is not necessary to purchase them to enjoy the game. It's up to the player's discretion to decide whether or not to purchase Diamonds.
