Farming the best gear in Diablo 4 is essential for crafting a powerful build. Legendary Aspects and Unique items significantly enhance your character's abilities, making it crucial to know the best farming methods. This guide covers the most effective ways to farm gear and Diablo 4 gold in Diablo 4, focusing on higher-level players who have reached level 50, completed the campaign, and progressed to World Tier 3.

Key Farming Methods
There are four main methods to farm Legendary and Unique gear in Diablo 4: Helltides, Whispers, Nightmare Dungeons, and Murmuring Obols. Helltides and Whispers are generally the most efficient as they allow for target farming, enabling you to hunt for specific gear types rather than relying on random drops.

1. Helltides
Helltides are considered the best method for target farming in Diablo 4 but are only available in World Tiers 3 and 4. To access them, you must complete the Cathedral of Light Capstone Dungeon.

Aberrant Cinders: Enemies in Helltide areas drop Aberrant Cinders, which can be exchanged for Tortured Chests. These chests have a high spawn rate for Legendaries, often dropping multiple items.
Strategy: Collect as many Aberrant Cinders as possible while playing through Helltide events. This method not only provides high-tier items from the chests but also increases your chances of earning Legendary loot during the cinder farming process.

2. Whispers
Whispers are bounties available across the Diablo 4 map after completing the campaign. These are accessible in all World Tiers, making them a versatile option for farming.

Grim Favors: Complete Whispers to earn Grim Favors from the Tree of Whispers. Turning in ten Grim Favors grants caches with an increased chance of containing rare gear.
Efficient Farming: Focus on Dungeons, which grant five Grim Favors each, or quickly clear Cellars for one each. The Tree of Whispers resets available Grim Favors every 90 minutes, providing a consistent source of farming opportunities.

3. Nightmare Dungeons
Nightmare Dungeons are excellent for accumulating loot and experience. They frequently drop Legendaries and occasionally Uniques.

Loot Galore: Legendaries often drop from monsters within these dungeons, and completing a Nightmare Dungeon guarantees a Legendary item, with a chance for it to be upgraded to a Unique.
Usage: While not ideal for target farming due to random drops, Nightmare Dungeons are great for collecting Legendaries and Uniques to scrap for crafting materials or to enhance your build while leveling up.

4. Murmuring Obols
Murmuring Obols are obtained from completing World Events and can be traded at the Purveyor of Curiosities for gear.

Gambling System: Use Murmuring Obols to gamble for gear, potentially yielding Legendary items.
Supplementary Farming: This method isn't ideal for dedicated target farming but is a good way to use Obols collected during other activities to get additional loot.

Early Game Farming Locations
While extensive gear farming isn't necessary at lower levels, some locations offer quick and easy farming opportunities. These locations are especially useful for quick upgrades before reaching World Tier 3.

1. The Frozen Tunnel Cellar
Location: Southwest of Kyovashad.
Strategy: This Cellar can trigger activities granting Greater Radiant Chests upon completion. It's near a World Event, making it easy to cycle between these two locations for efficient farming.

2. Ancient Syphon World Event
Location: Western Ways, Fractured Peaks.
Strategy: This event is easy to activate and reset, offering high rewards compared to its difficulty. Defeat three enemy hordes and a boss to earn a Greater Radiant Chest, which can drop Legendary items.

3. Anica's Claim
Location: East of Kyovashad in Fractured Peaks.
Strategy: This Animus Dungeon is filled with Elite enemies, increasing the chance of dropping Legendary gear. If the dungeon doesn't reset immediately, alternate with World Events or use the multiplayer respawn trick.

4. Radiance Field Cemetery World Event
Strategy: This event in the Hold Your Ground area is a short, quick-reset event ideal for farming Legendary loot for levels 20-35. Logging out and back in can accelerate the reset process.

5. Fields of Hatred
Location: PvP areas in Dry Steppes and Kehjistan.
Strategy: These areas have high Elite spawn rates, granting increased chances for Legendary drops. Disable PvP by removing the Mark for Blood to farm without worrying about other players.

Conclusion
Farming Legendary and Unique gear in Diablo 4 is crucial for building a powerful character. Focus on high-reward activities like Helltides and Whispers for targeted farming, while Nightmare Dungeons and Murmuring Obols can supplement your gear collection. For early-game players, specific locations like The Frozen Tunnel Cellar and Ancient Syphon World Event provide quick farming cheap Diablo IV gold opportunities. Utilize these strategies to maximize your loot and enhance your Diablo 4 experience.
