In Lord of Hatred, Diablo 4 completely redesigned the gem system, adjusting the attributes of various gems and introducing two new gem tiers: Horadric Gem and Flawless Horadric Gem.
Flawless Horadric Sapphire is a rare and powerful gem that increases frost damage and frost resistance. However, players typically need to spend up to twenty hours farming for just one.
But in Season 14, Season of Death Awakening, a bug allows players to farm Flawless Horadric Sapphires in just one hour. This bug has not yet been fixed.

Core Mechanics
Normally, farming Flawless Horadric Sapphire in Diablo 4 was a lengthy process:
Players needed to collect a large number of Sapphire Fragments, then use them to craft five Horadric Sapphires, and finally use Horadric Cubes to combine Horadric Sapphires into a Flawless Horadric Sapphire.
Previously, players could farm these fragments in Nightmare Dungeons and craft Flawless Horadric Sapphires, but this process was extremely time-consuming.
In Season 14, this changed. First, players could unlock Branching Pathways, nodes related to Nightmare Dungeons, through War Plan system.
Branching Pathways allowed players to choose from several bonus affixes at the end of each Nightmare Dungeon level, including Gem Reserve - which granted players more gem fragments.
More importantly, the benefits of this affix increased significantly with each level. According to player testing, level 3 is the most suitable level for farming gem fragments. This is because level 3 has moderate difficulty and offers very substantial affix rewards.
However, Nightmare Dungeons currently has a bug: according to player feedback, if a player selects escalating Nightmare Dungeons and teleports back to town, returning to the dungeon may reset it to a normal dungeon, no longer retaining the escalating status.
Under certain conditions, players can exploit this phenomenon to reset Nightmare Dungeons, causing all chests and enemies to respawn immediately, but the affixes will remain unchanged.
Therefore, players can repeatedly farm Nightmare Dungeons level 3 to obtain a large number of Sapphire Fragments in a short time, thus quickly farming Diablo 4 Flawless Horadric Sapphire. This will save a significant amount of time compared to the normal farming method.
Operation Flow
Now that we understand the mechanics, we can proceed with the specific operations.
Obtaining Affix Combination
The first and most time-consuming step in this farming method is obtaining the ideal affix combination in the first two levels of Nightmare Dungeon.
First, players need to farm Gem Reserve of the target type. Since the target is Sapphire Fragments, Sapphire Reserve is required.
Second, players need to farm Dark Omen. This affix has a special effect in Nightmare Dungeon; players will definitely encounter The Butcher in Dungeon, and there is also a chance to encounter Treasure Goblin or Helltide Boss. Defeating these monsters will reward players with additional Gem Shards.
Resetting Dungeon
Once players successfully farm the target affix and enter the third level, they should clear all chests on that level and defeat the additional boss summoned by Dark Omen, but not the final boss of that level.
Next, players need to teleport back to the main city and then randomly enter a normal dungeon, such as Seer's Reach in Skovos region.
Upon entering the normal dungeon, players need to immediately open Sanctuary map and teleport directly back to the third level of Nightmare Dungeon.
If done correctly, players will find that the dungeon level has been completely reset - all chests are openable again, Dark Omen boss can be defeated again, and the player's affix combination remains unchanged. At this point, players can begin a new round of opening chests and farming gem shards.
Additionally, players can activate Recurring Nightmare node. In Diablo 4 Season 14, this affix gives Nightmare Dungeon boss a chance to drop Escalation Sigils - essential items for unlocking Nightmare Dungeon, thus enabling infinite Nightmare Dungeon farming.
Efficiency Comparison
According to experiences shared by Diablo 4 players in the community, if this farming method is applied on Torment XII difficulty, a single chest in Nightmare Dungeon's third level can yield approximately 270,000 target-type gem shards, and defeating Dark Omen boss can yield approximately 750,000 shards.
With such incredible efficiency, this player obtained a Flawless Horadric Gem in less than an hour. In comparison, traditional farming methods would take nearly 20 hours to achieve the same result, making it dozens of times less efficient.
Potential Risks
However, since this method exploits a bug in Diablo 4 Season 14, it carries potential risks. Once this bug is fixed, players will no longer be able to farm Flawless Horadric Gems, and of course, Flawless Horadric Sapphires, in such a short time.
This bug bypasses the normal dungeon reset process and significantly increases shard acquisition efficiency, clearly contradicting the design team's original intentions; therefore, its fixing is inevitable.
In fact, some players have already reported the existence of this bug to the developers. Based on past experience, the developers may fix it when it becomes widely known in the player community. Currently, the bug is known to many players, and it is very likely to be fixed in a few days.
The above is a method for quickly farming Flawless Horadric Sapphire in Diablo 4 Season 14, Season of Death Awakening. In addition, you can follow EZG Facebook; we may be giving away gifts to followers in the future, which may include Flawless Horadric Sapphire.
If you want to use this farming method, please act quickly before the bug is fixed.
