↖ Farming with Team

Create a party, not only will this make farming easier, but it'll double your materials through rotations. To find people to group up with you can use trade channels in town or go to the front of the summoning zone and ask around. There are also special Discord servers dedicated just for teaming up.

↖ Efficient Whisper Event Farming

These will be your primary source for Mucus Eggs, all Whispers provide rewards but seasonal whispers give high ones so pay extra attention to those, they happen every 30 minutes. Another one is Tremors which happens every hour and a half which gives Whisper caches that contain Grim favors and other resources.

↖ World Bosses and PVP Whispers

Whenever there is a world boss available remember that Whisper events spawn more frequently on the same day as them. The PVP Whispers aren't as frequent but they do require you to kill specific enemies like Kazar Abomination, do these if you see them because their drop rates are good too.

↖ Harvest Whispers and Dungeon Events

Go to multiple objectives within zones during Harvest Whispers so you can turn in quickly and keep getting materials at a steady rate. Also when dungeon Whispers show up don't ignore them because they usually have codex powers that'll suit your build well.

↖ Mastering HellTide Chest Farming for Grigoire Materials

For living steel chests just go through HellTide zones until chests drop then pick them up. They give living Steel which brings out Grigoire who might give you more Shards of Agony while farming for Duriel’s ritual. Make sure to find dense areas of HellTide zones, this will make farming much faster.

↖ Optimizing Your Farming Strategy

Only focus on seasonal Whispers and combine nightmare dungeon runs with Whisper objectives. Lastly, always align your farming with HellTide events that include Whispers so you can maximize every trip.

Conclusion

Summoning Duriel in Diablo 4 is not easy at all but if you manage to do it, expect great rewards. Use this guide to farm efficiently and take full advantage of Whisper events, Bosses and HellTide zones for grinding materials needed to summon him.
