List of Contents

As of Season 10, the best way to farm Shard of Agony is by defeating Grigoire and opening his boss hoard using 12 Living Steel. Keep in mind that you can get higher drop rates in Torment I or above so make sure your build is optimized enough to take on higher difficulties.

Alternatively, the Shard of Agony can also be obtained by defeating Echo of Varshan and opening his hoard using 12 Malignant Hearts.

Running Undercity of Kurast with the Tribute of Titans grants a chance of obtaining Shard of Agony along with other Lair and Uber Boss Keys. This is the second most optimal way of farming Shard of Agony as its drop rate is quite high.
Do note that the Tribute of Titans has a low drop rate that you can target farm in Nightmare Dungeons, Tree of Whispers, or Infernal Hordes.
In order to use your Shard of Agony, you first have to defeat Duriel in the Gaping Crevasse at Kehjistan. Doing so will spawn his hoard chest inside the boss area where you can use 3 Shard of Agonies to open it.
Take note that Lair Bosses are now free to summon but their rewards now drop from their respective reward chests called hoards.
