Blood Thief Exploit Hotfix Explained

Blizzard chooses from multiple steps of action against exploiters of the bug

Diablo III Hotfixes
Blizzard has completed their fixes for the recent Diablo III Blood Thief Goblin exploit, along with punishments on the accounts that were involved in exploiting it. Recent Blizzard Blues posts detail exactly what steps were taken to deal with exploit, along with other issues such as a bug in Greater Rifts, and another with the Witch Doctor Zunimassa's Haunt Set.

Blood Thief Hotfix and Account Actions
Blizzard used multiple levels of punishment for the players who exploited the Blood Thief Goblin bug, including rolling back certain accounts to the start of Season 3 or when Patch 2.2 landed. Community Manager Lylirra details the actions taken, and why.

One side effect of the hotfix is that all Treasure Goblins now only drop items for players who were in range when the goblin was killed. This makes split farming a little less rewarding. The portals that occasionally come from killing a goblin, that leads to the Realm of Greed, are still accessible by anyone who was in the game when the goblin was killed.
UPDATE – April 21 @ 6:05 p.m. PDT

While this issue is now resolved, we know a lot of players have questions about what happened and how we responded, so we wanted to take some time to discuss a few of the details with you here.

Following the launch of patch 2.2.0, players discovered an exploit that caused Blood Thief goblins to drop a larger number of Blood Shards than intended. The exploit could only occur in Greater Rifts when in a multiplayer group and required a specific sequence of steps to activate.

As soon as we were able to able to verify the exploit and identify its underlying cause, we immediately began working on a hotfix for PC. The hotfix was deployed in all gameplay regions on April 16, which made the following changes to the game:

  • In order be eligible for experience or loot from any monster (including Treasure Goblins), you must do damage to it or be in the same area when it is killed

  • If you are in a Greater Rift, you are no longer eligible for any experience or loot gained by party members outside of the rift

For console, this particular change cannot be implemented via hotfix, so we've temporarily disabled all Blood Thief goblin spawns on PlayStation 4 and Xbox One until further notice (pending a future patch).

From there, taking the complexity and impact of the exploit into consideration, we also elected to action accounts on a case-by-case basis. In general, one of three things occurred:

  • Accounts which were found to have both used the exploit excessively and publicly promoted its use were permanently banned.

  • Accounts which were found to have used the exploit excessively, but did not publicly promote it, were rolled back and their associated heroes removed from active Leaderboards (both Seasonal and non-Seasonal).

  • Accounts which were found to have used the exploit to a limited degree (or quickly stopped once realizing the scope of what was happening) were effectively pardoned. We understand these situations can inspire a certain level of curiosity and that it may not always be immediately clear if you’re undermining intended game mechanics. Mistakes happen, but we hope this leniency won’t be taken for granted in the future.

All in all, this incident has shown us that the vast majority of players, upon encountering an in-game exploit, will not only put sportsmanship and fair play above personal gain, but will also work to bring the matter to our attention quickly via channels like, our online webform and ticket system, and these very forums. (We even received a few Twitter DMs, Skype messages, and personal emails too!) So, on behalf of the development team, I just want to say thank you to those of you who took the time to notify us, as well as apologize for any inconvenience caused a result.

As noted in our original post, maintaining an enjoyable and equitable play experience is very important to us, and we’re going to continue to monitor the game as well as take steps to prevent exploits like this from happening again.

Exploiters Misusing Account Rollbacks
Some players who were given actions on their account for exploiting the Blood Thief Goblins issue, decided to use the official Account Rollback system to try to get around the punishment. That was dealt with, as well. Reportedly those accounts were once again rolled back to the start of the Season or patch so their hero progress was deleted, and all three of their official rollback allowances were removed. It is really not worth trying to cheat, folks!
Thanks for the reports! Our Customer Support team is already investigating and will be taking action as needed.

Improvements to Crafting Resource Management
Grimiku took to the forums to discuss a year-old thread, where he had originally mentioned an idea that the developers had for changing all materials into currency-style user interface. That system wasn't implemented, but there have been gradual improvements through multiple patches, to make crafting materials and gems easier to pick up and store.
As some of you may have noticed, my original post about potential updates to crafting resource management was created over a year ago. A lot of changes relating to crafting, inventory management, and looting items in bulk have happened since then, and chances are there will be more changes that affect them in the future, too. At this time, we’re no longer planning to implement a currency-style storage system for crafting materials, and we don’t have any additional related updates to provide. That said, we do plan to continue to make improvements to these systems when it aligns with our design goals, and makes sense for us to do so.

As a refresher, here are some of the more recent changes that have improved on the crafting system and/or inventory management which are already in the game.

  • All normal Health Potions are now bottomless, and regular Health Potions no longer drop
  • There is now a “vacuum pickup” system to make gathering large amounts of certain items (including gems and crafting materials) easier
  • A Wardrobe has been added, which now manages cosmetic items like pets, wings, pennants, and portrait frames
  • Players can now increase their Blood Shard cap by reaching new personal bests when playing in Solo Greater Rifts
  • When crafting gems and items, the entire quantity will be crafted at once

How about you fix arcane Dust, we can't get it and its the least rare of the mats needed in items, yet its the most rarest to get.

either make something to break crystals into dust, or dust required is 1 dust per item for any type of craft.

I don't have a problem with arcane dust. You guys just never stop crying!

LOL - I manage my arcane dust levels too. I craft Reaper's wraps and also enchant quite often which eats up my arcane dust pretty quickly. I have several stacks of 5000 of veiled crystals and Death breaths however.

The changes were very nice however, thanks devs. The potion change and the vacuum pull are both helpful. Also the gem thing is also nice, i used to hit the craft gem button and then go on a break to get coffee or make lunch. Now it's almost instant!

Need more reusable part and arcane dust drops....why do rift guardians drop 50 vc, 4 ad, 3 rp......need fixes somewhere

I don't fully understand the argument of "we've improved in some areas, so we are holding out on this area". Stash space continues to be an issue. It's great that you guys implemented the recent changes, as you mentioned, but really is there any good reason not to follow through with making materials a currency? Listing other QoL improvements isn't really relevant to this one, it just detracts from it.

Greater Rift Timer Bug
A bug is being investigated regarding the timer in Greater Rifts. Occasionally it will already be partially completed as soon as players enter the Rift.

I just get into a Public Game with a friend and when we start the Grift Level 35, the clock already was at 75% more.

Thanks for mentioning this, Xeyrruken.

We've passing any reports we’ve seen on this bug to the appropriate folks. While we don't have an ETA yet on when this issue will be fixed, we'll let you know as soon as we have an update!

Bug with Zunimassa's Haunt Set
The Witch Doctor class Set Zunimassa's Haunt was overhauled in patch 2.2.0, and is increasingly popular. There is currently a bug that pops up when multiple Witch Doctors in a party have the set, and are attacking the same monster. That bug will eventually be fixed, either by a hotfix or in a small patch, such as the patch 2.2.1 on the PTR.
Thank you, everyone, for reporting this issue! We've identified a bug that sometimes prevents players from benefiting from Zunimassa’s 6-piece set bonus when there's more than one Witch Doctor attacking the same monster(s). We’re working a fix right now, but we don't yet know if this is something that can addressed via hotfix or if it will require a client-side patch. As a result, we also don’t have a time frame to share.

Thanks again for your reports, and for your patience in the meantime. We'll be sure provide more information once it’s available.
