Within Diablo Immortal's array of upgrades, currencies, and reward
Diablo IV Gold system, legendary gems are the ones where the business model is at its hardest. Blizzard and NetEase have not been so stupid as to sell directly through a loot bag or gacha feature but what they have come up with is somehow, even more concerning. Legendary gems only drop from the bosses that are randomly placed in Elder Rift dungeons, and you can only guarantee that you will get a legendary gem by applying an legendary crest modifier the dungeon before starting the dungeon. Other than that, drop rates of legendary gems are incredibly low.
While you do not have to pay any money for the game, you can only receive one legendary crest each month, and even buying a battle pass will only bring you one or two more legendary crests each month. Beyond that, you'll have to buy them on your own. Legendary crests are priced between $2 and $3 one-time.
The number of gems needed to increase the power of your character's equipment, especially considering the extremely low drop rates of gems that have five stars, is the reason the cost of maxing out your character's potential on Diablo Immortal has been estimated at between $50,000 and $100,000 and possibly more when you dive into the gem resonance system. (Rock Paper Shotgun has a very thorough cost breakdown that falls on the sensible end of this spectrum.)
Diablo Immortal has been given an extremely rough ride due to this model of business which is perhaps not in the way it should, considering popular free-to-play rivals such as Genshin Impact and Lost Ark have a lot of gacha mechanics that entice large-spending "whale" gamer. Diablo's fame and reputation with the core PC gaming player
buy Diablo 4 Gold base, earned over the span of nearly a quarter century, is surely an important factor. But it's also true that this system is uniquely problematic, and the very nature of Diablo games could have an impact on that.
