The Diablo IV Gold Immortal character comes with six legendary gem slots. Each gem is assigned the corresponding rating, which ranges from one to five stars, which cannot be changed, and can greatly impact the power of the gem. Gems with five stars are much more scarce than ones with one star. Legendary gems are upgradeable and the simplest way to do this is taking in other gems of legendary status. A gem that is upgraded can later be further enhanced with an "gem resonance" system that requiresguess what -the addition of more legendary gems as much as five additional gems per gem slot.

If you want to maximize your characters -- and maximising your character is what Diablo is all about, you'll need plenty of legendary gems. You need to choose the best ones that best suit your needs, to get good star ratings, to upgrade the gems you have, and then to put them into the gem's resonance slots. It's endless.

Within Diablo Immortal's array of options for upgrading, currencies, and reward system, legendary gems are the ones where the business model is at its hardest. Blizzard and NetEase have not been so extravagant as to market them directly through a loot container or gacha mechanism, but what they have created is, in a way, even more troubling. Legendary gems only drop from those bosses found in the randomly generated Elder Rift dungeons, and you can only ensure an epic gem drop by applying the legendary crest modifier the dungeon prior to starting the dungeon. In other words, the rates of drop for gems with legendary status are extremely low.

If you don't spend any money on the game, you can just get one legendary crest every month. Buying one of the battle passes will bring you one or two more legendary crests each month. Beyond that, you'll have to buy them directly. Legendary crests work out at approximately $2 and $3 per piece. The sheer amount of gems you'll require for your character's best equipment and abilities, particularly when you consider the extremely low drop rates of five-star gems. This is the reason the total cost to max your character's abilities within Diablo Immortal has been estimated at approximately $50,000-$100,000 -and buy Diablo 4 Gold possibly more in the case of getting into the gem resonance system. (Rock Paper Shotgun offers an extensive breakdown of costs that is at the more conservative end of this scale.)
