3. Strongholds and Whisper Caches
Clearing Strongholds: Clearing a stronghold for the first time on any character provides substantial rewards, including the chance to obtain runes.
Whisper Caches: Complete Tree of Whispers activities to accumulate Grim Favors, which you can exchange for Whisper Caches. While rune drops aren’t guaranteed, these caches offer a chance to acquire them.
4. Jeweler’s Rune Crafting
If you need a specific rune and farming isn’t yielding the results you want, the Jeweler can help you fill the gaps.

Craft Runes: Combine three identical runes to create a new, random rune for 4,000 gold.
Strategic Use: Use the Jeweler to convert unwanted runes rather than farming duplicates. This is especially helpful for completing your rune collection.
