World Events: Participating in Diablo 4 Gold world events that feature elite enemies can also be an effective method. Many world bosses and event challenges will summon elite mobs, allowing you to collect Stygian Stones as part of the event rewards.

Dungeons in Diablo 4 are another excellent source of Stygian Stones, especially when run repeatedly. Certain dungeons have higher drop rates for crafting materials, including Stygian Stones, due to their enemy density and the presence of mini-bosses or elite monsters.

High Enemy Density: The more enemies you defeat, the more chances you have to collect Stygian Stones. Look for dungeons that are packed with mobs, particularly those that spawn large groups of elite enemies.

Mini-Boss Encounters: Some dungeons feature mini-bosses that drop rare materials. These encounters increase your chances of finding Stygian Stones, as mini-bosses often have better loot tables than regular enemies.

Focus on clearing dungeons efficiently by running through them with a speed-farming build. Use AOE (Area of Effect) attacks to clear out mobs quickly and ensure that you're maximizing your time.

World bosses in Diablo 4 often drop high-quality loot, including Stygian Stones. Participating in world boss events not only rewards you with powerful gear and crafting materials but also provides a chance to gather large quantities of rare items in a short period.
