Diablo 4 Unbroken Bones Not Dropping: Call of the Underworld Quest Fix

Diablo 4 Unbroken Bones not dropping was a bug affecting the Necromancer class mechanic quest Call of the Underworld. Some monsters that should have contributed quest materials failed to drop them, leaving players with an incomplete objective even after fighting additional enemies.

Blizzard addressed the problem in patch 3.2.3, Build #73883, released October 14, 2026 on all platforms. If you’re returning to the quest after the update, here’s how to confirm that you’re on the fixed version and what to check before assuming your Necromancer is stuck.

Diablo 4 Unbroken Bones not dropping: what was broken?

The Diablo 4 Unbroken Bones not dropping bug affected monster kills during the Necromancer’s Call of the Underworld quest. After updating to patch 3.2.3, follow the marked objective and collect the bones from defeated enemies.

The Diablo 4 Unbroken Bones not dropping fix applies to Call of the Underworld, not unrelated crafting materials or quests.

When was the Unbroken Bones bug fixed?

Patch 3.2.3 (build 73883) launched October 14 for PC, Xbox and PlayStation. Restart after updating, then resume your tracked Necromancer quest.

If you’re reading a guide written before October 14, it may still tell you to wait for a patch. The Diablo 4 Unbroken Bones not dropping fix is already part of the released update.

How to get Unbroken Bones during the quest

Track Call of the Underworld on your Necromancer and follow the quest marker to the relevant enemy encounters. Defeat the monsters required by the quest and collect or register the Unbroken Bones as the objective asks.

Blizzard’s fix restores the missing item-drop behaviour; it doesn’t announce a new universal monster spawn, alternative crafting recipe or merchant purchase path. Use the active quest objective for the correct targets instead of hunting an unrelated dungeon.

What to do if the bones still do not appear

First check the Diablo IV client is updated to patch 3.2.3 or later. Then track Call of the Underworld explicitly and verify that the correct class and quest are active. Defeat monsters within the indicated objective area and inspect the progress.

For Diablo 4 Unbroken Bones not dropping after the fix, don’t immediately delete your character or reset the campaign. Blizzard hasn’t said that those destructive steps are needed for this quest.

Is this the same bug as Prime Evil Powers?

No. Patch 3.2.3 also prevents a seasonal questline lockout caused by using Prime Evil Splinters too early. That bug has a specific recovery route involving a new character in the same gameplay partition, because the fix doesn’t repair already stuck seasonal characters.

The Unbroken Bones problem has its own separate drop fix. Diablo 4 Unbroken Bones not dropping shouldn’t automatically be treated as a seasonal Prime Evil bug or require completing another character’s seasonal storyline.

Does the patch repair progress automatically?

Blizzard confirms the monster drop problem is fixed, but doesn’t specify a separate retroactive quest-completion grant for players who previously collected too few bones. Return to the quest after updating and check whether the normal drops now allow progress.

If the issue continues, record your build number, platform, character class and quest step before reporting it. Diablo 4 Unbroken Bones not dropping after a confirmed patch is useful information for support to distinguish from the older fixed behaviour.

Quest fix checklist

Install the October 14 patch or later, play the Necromancer, track Call of the Underworld and follow the indicated monster objective. Check for the restored Unbroken Bones drops, then complete the quest normally.

If the quest was already active when you updated, track Call of the Underworld again and defeat the monsters indicated by the objective. Check the number of Unbroken Bones you’ve collected before returning to the quest turn-in.
