Diablo 4 Season 14 Greystone Pet Guide: How to Unlock the Auto-Loot Pet and Boost Endgame Farming Fast?
Having a pet that automatically loots your gear in Diablo 4 Season 14 sounds pretty cool.
Greystone Pet was officially released on July 17th as a limited-time reward for Season Journey Rank 6.
With the recent Server Hotfix 1 update on July 21st, obtaining it has become even easier. Equipping it allows for zero-latency automatic looting of a huge area of gold, crafting materials, and Gem Fragments, making it a powerful aid for leveling up this season.
Therefore, now is definitely the best time to get a Greystone Pet and use it for your runs.

How to Unlock?
The only way to obtain Greystone Pet is to complete all the milestone quests in Diablo 4 Season of Death Awakening Season Journey Chapter 6. The core quest of Chapter 6 is to successfully defeat the season finale boss, Corrupted Reaper, on T6 difficulty.
After fulfilling all the conditions and defeating the boss, the system will automatically complete the quest and unlock Greystone Pet. The boss drops Reaper's Hoard upon defeat. If you have extra Superior Lair Keys, you can open the chest; otherwise, you can choose not to open it, as this won't affect your pet acquisition.
After unlocking, remember to return to Wardrobe in any major town, switch to Pet page, and equip the stone dog with the blue glowing mouth. Combined with Server Hotfix 1 update, this allows for a perpetual, highly efficient monster-farming strategy.
Gameplay Flow
Helltide Ruptures and Reputation
This is the first step in Diablo 4 Season 14 perpetual farming strategy. The core idea is to quickly accumulate season reputation to obtain a large amount of high-level boss challenge resources for free, thus forming a stable gear farming loop.
After the July 21st update, Diablo 4 Superior Lair Keys were officially added to the reward pool of the infinitely repeating season reputation reward, Glints of Hope Cache.
This means players no longer need to rely on the traditional key-based upgrade path, but can obtain the necessary tickets to challenge high-level bosses in a more direct and efficient way.
Therefore, all you need to do is take your Greystone Pet to Helltide and farm Ruptures and Realmwalkers like crazy.
Since the monster density is much higher in Helltide's Ruptures, you only need to focus on pulling monsters and bursting down enemies.
Your Greystone Pet will automatically and without delay absorb all the gold, high-tier materials, and the massive amount of Gem Fragments needed to craft Flawless Horadric Gem over a huge area.
This not only reduces the time players spend frequently stopping to pick up resources but also prevents the farming rhythm from being disrupted by sorting loot, significantly improving overall farming efficiency.
With proper route planning and team play, you can accumulate reputation faster and continuously obtain the resources needed to unlock higher-level boss challenges, preparing for the subsequent bulk acquisition of Mythic Uniques.
Kurast Undercity
The second step is to quickly farm Undercity. The core objective is to use Tributes you've accumulated from Helltide, Pit, etc., to selectively farm Mythic Uniques in bulk.
Server Hotfix 1 significantly boosted the loot drop rate after completing Diablo 4 Season 14 Undercity using Mythic Tributes of Armaments, especially on T10 and higher difficulties.
Upon completion on T12, the drop rate is now guaranteed to be at least one Mythic Unique, drastically reducing the uncertainty of obtaining endgame gear.
It's important to note that Undercity requires a time limit, so avoid wasting time there. Greystone Pet's auto-pickup ability is crucial here, automatically collecting Gold, materials, and other resources along the way without requiring players to return, minimizing the risk of failure due to time constraints.
Combined with the abundant Superior Lair Keys and Tribute resources obtained in Helltide, players can create a complete loop: farming Helltide for resources, entering Kurast Undercity to challenge the boss, and acquiring Mythic Uniques.
This is one of the most efficient Mythic Unique acquisition routes in Diablo 4 Season of Death Awakening.
Pandemonium Rift
The core objective of this step is to utilize Superior Lair Keys accumulated by players in the first phase through Helltide Ruptures and Realmwalkers, converting them into more consistent boss challenge opportunities and unlocking greater endgame rewards.
Players need to travel to Zarbinzet area to enter Pandemonium Rift and, at Torment VI or higher difficulty, repeatedly activate Reaper's Hoard using Superior Lair Keys.
Following Diablo 4 Season 14 Server Hotfix 1 improvements to key acquisition, players can access this area more often, repeatedly activate Hoard for extra rewards, and progress through the main objectives required to unlock Greystone Pet content.
Furthermore, after the latest patch removed the limitation of equipping only a single Mythic Unique, players can now use multiple Iconic Mythic Uniques at the same time, including Harlequin Crest, The Grandfather, and more.
Combining the gear advantages and key resources accumulated in the first two phases, Pandemonium Rift will be the final element in the entire gear-farming cycle: unlocking rewards with Superior Lair Keys, defeating Corrupted Reaper for additional gains, and further enhancing character gear to prepare for tackling increasingly difficult endgame content.
In short, Greystone is absolutely essential as you enter Diablo 4 Season of Death Awakening endgame. It directly boosts your farming efficiency and speed, especially in the later stages when you desperately need large amounts of gold and materials. All you need to do throughout the entire process is unleash your skills and grind monsters.
