As you progress through the season, your focus should shift to more challenging activities, such as Nightmare Dungeons and the Horadric Vault. These higher-difficulty dungeons introduce tougher enemies and significantly increase the number of vials dropped. In addition to Horadric Vials, you'll also find a wealth of other upgrade materials, making these dungeons a vital source of Diablo IV gold resources for late-game progression.
Once you start obtaining high-level rewards, you'll want to prioritize farming the Horadric Fortress. This area, designed for endgame players, drops the largest quantities of D4 Gold Horadric Vials and other critical items, making it an invaluable location for powerful upgrades.
