Mmoexp Diablo 4 Items: Plan for Resource Farming from Rozemondbell's blog

6. Plan for Resource Farming

Whisper Caches are an excellent source of materials and Diablo 4 Items resources, especially if you’re farming for specific crafting materials. When planning your Whisper runs, keep an eye on caches that yield the items you need. Some caches contain rare materials, salvageable items, and potions that can support item upgrading or resource management.

7. Know When to Stop and Turn In

You can turn in Grim Favors for Whisper Caches at the Tree of Whispers as soon as you have enough for a cache (10 Grim Favors), but it can be more efficient to accumulate a few caches’ worth and turn them all in at once. This approach minimizes downtime and ensures you’re always out completing Whispers instead of constantly returning to the Tree.

8. Group Up for Faster Completion

If possible, complete Whispers with friends or other players. In a group, you’ll tackle objectives faster, and everyone benefits from the collective completion of Whispers. This can be especially useful in high-density areas with elite enemies or tougher objectives. Plus, shared loot from cheap Diablo 4 Items elites and events can make the run even more profitable.
