This Diablo 4 farming guide will provide valuable information on obtaining ultra-rare items in the game. We have gathered community knowledge on the best farming locations for these items. Recently, the developers confirmed that these items could be dropped at or above level 85, with an item power of 820. Many players have already reported obtaining these ultra-rare items, so let's investigate the details.

Identifying Targeted Items and Best Farming Locations:
a. Ultra Rare Weapons: The one-handed sword, "Tomb Raider," and the two-handed sword, "Grandfather," are among the ultra-rare weapons available.
b. Ultra Rare Helmets: Two ultra-rare helmets, including the highly desired "Harley Quinn's Quest of the Shackle."
c. Rings and Amulets: These accessories are dropped randomly throughout the game.
The best farming locations for these items are Earthenwood and Cultist Refuge. Cultists specifically increase the drop rate of helmets, making them ideal for farming ultra-rare helmets.

Farming Strategy and Tips:
a. Saving Maps: Save dungeon maps for Earthenwood, Cultist Refuge, Even Concave, and Golem Slums, as these locations have monsters that drop the targeted items.
b. Magic Find: Look for dungeons with the "Magic Find" attribute, which increases your chances of finding rare items.
c. Estimating Drop Rates: obtaining items like Harley Quinn's Quest may require killing around 800,000 monsters. Drop rates can be extremely low, so be prepared for a lengthy farming process.
d. Resetting Dungeons: Resetting dungeons is an effective way to farm the same dungeons repeatedly, increasing your chances of obtaining ultra rare items. Find groups of players with similar maps to maximize your farming efficiency.

Additional Considerations:
a. Amulets and Rings: Keep in mind that these accessories have random drop rates, making them more challenging to farm for specific ultra rare items.
b. Exp-Focused Maps: Some maps prioritize experience gain, but if your goal is to farm monsters for ultra rare items, focus on maps that increase the drop rate of helmets, such as those with cannibals and cultists.

Conclusion:
By following this Diablo 4 farming guide, you'll be equipped with the knowledge to farm for ultra-rare items and D4 Gold efficiently. Identify your target items, choose suitable farming locations, and use monster family and type bonuses. Save maps, prioritize magic finds, and consider resetting dungeons to increase the chances of obtaining these items.
