If you want to maximize your character -- and increasing your character is the essence of Diablo is about -- you need tons of legendary gems Diablo 4 Gold: to find those that are right for your build, to roll excellent star ratings, to upgrade the gems you have and then to put them into the gem's resonance slots. It's endless.
There are a lot of Diablo Immortal's currency, upgrade paths, and reward system, legendary gems are where the business model gets bitten the hardest. Blizzard and NetEase haven't been as stupid as to sell directly through a loot container or gacha mechanism but what they have developed is, somewhat, more troubling. Legendary gems can only be obtained from the bosses of the randomly generated Elder Rift dungeons, and you can only ensure the legendary gem's drop by applying an legendary crest modifier the dungeon in advance of starting the dungeon. If not, the drop rates for gems that are legendary are very low.
For those who do not pay for the game, you can just get one legendary crest every month, and even buying an account for battle will only bring you two or three additional legendary crests per month. Then, you'll have to purchase them from the source. Legendary crests cost somewhere between $2 and $3 each. The sheer amount of gems required to increase the power of your character's equipment especially when you consider the very low drop rates of five-star gems, is one of the reason the cost of maxing out your character's potential in Diablo Immortal has been estimated at between $50,000 and $100,000 -- and perhaps more in the event you get into the gem resonance system. (Rock Paper Shotgun comes with detailed cost breakdown that is at the more conservative end of this scale.)
Diablo Immortal has been given an extremely rough ride the business model it is based on and perhaps in a way in light of the fact that free-to-play games like Genshin Impact and Lost Ark are not without similar gacha mechanisms to draw in huge-spending "whale" users. Diablo's popularity and fame with a core PC gaming community, accumulated over the span of nearly a quarter century, is certainly a factor. However, there is also a fact that this game is particularly challenging and the nature of Diablo games has something to do buy Diablo IV Gold.
