The key to winning the season 10 of Diablo 4 is not only the build that you have chosen, but also the knowledge of the complex systems of gears and economy of the game. The important thing about the endgame is to get the right items and amass enough Diablo 4 gold to maximize the power of your character and have an enjoyable experience going through the endgame.
Powerful characters in Season 10 are based on the fact that the itemization system is sophisticated. There are Common equipment up to Mythic Unique equipment, with Ancestral and Unique being the most desired equipment to play at end game. These top level items, beginning to drop in Torment I difficulty, have Greater Affixes: stat rolls that are 1.5 times stronger than regular ones. There is a unique sound and visual indicator that their drop is approaching, which informs you of a potentially game-changing piece of gear.
There are some important operations where one can best acquire better equipment. One of the most popular endgame activities is the Infernal Hordes, which provides a flexible form of reward, where you can acquire Burning Aether through each run and to obtain different prizes. Likewise, the Tree of Whispers is offering consistent rewards at the end game; once you finish the campaign and earn Grim Favors, which you earn by completing world objectives to get cachees with Legendaries, Uniques, and precious material. These activities will also be effective in filling your arsenal with the best available items.
After having a good base of gears, the Occultist would be necessary to fine-tune it using Legendary Aspects. Using this system you can use legendary items to pull powers and make them permanent on a well-rolled Rare or Legendary piece of gear, effectively adding the effects of powerful items to objects with the best possible stats. Subsequent upgrades include Tempering and masterworking at the blacksmith that brings affixes and dramatically increase the power and stat of items.
World Events and specific Dungeon farming can work very well to achieve a diverse gaming experience but with high rewards. Accomplishing things on your map, especially the ones that are especially effective such as the ones close to the Bear Tribe Refuge in Fractured Peaks give you direct buy Diablo 4 gold rewards and loot to sell. One such strategy is to teleport to town to sell unwanted products and come back to the town with the next session with the event being reset.
