Longtooth may currently be forgetting his half of the deal.
Two fresh bug reports from September 5 describe players using Mythic Tributes in the Undercity only for the final Longtooth encounter to fail in ways that leave the Tribute consumed and the player with no reward. In one case, Longtooth reportedly froze after being killed and continued his spinning animation indefinitely. In another, a player says they killed him twice using Mythic Tributes and received no drops at all.
These are player reports, not confirmation from Blizzard that every Longtooth run is affected. But Mythic Tributes are valuable enough that even an occasional failure is considerably more painful than the average boss deciding to behave strangely.
Longtooth Apparently Died Without Actually Dying
The clearest new report comes from a player who used a Mythic Tribute for an Undercity run on September 5.
According to the bug report, Longtooth reached the end of the fight but then became stuck instead of completing his death sequence. His whirling animation continued, the encounter never properly resolved and no loot appeared.
The player attempted to teleport out of the Undercity and return.
Longtooth was still there.
Still spinning.
Still refusing to acknowledge the minor administrative detail that his health bar had reached zero.
The Mythic Tribute, meanwhile, had already been spent.
The player understandably asked either for the Tribute back or for the Mythic reward they believed the run should have produced.
A Second Report Says Two Mythic Tribute Runs Dropped Nothing
Another bug report appearing the same day is even more direct. Its title states that the player killed Longtooth twice while using Mythic Tributes and received no drops at all.
That does not necessarily prove both reports share the same technical cause. One describes a boss death sequence becoming stuck. The other describes completed kills that apparently failed to produce loot.
But from the player's perspective, the distinction is not terribly comforting.
In both situations:
- a Mythic Tribute was consumed
- the player completed or effectively completed the Longtooth encounter
- the expected reward did not arrive
That is the part that matters.
Mythic Tributes Are Supposed to Make Undercity Runs Worth More
Tributes are not ordinary dungeon keys. Blizzard designed them as modifiers that let players deliberately influence an Undercity run and its rewards.
Higher-quality Tributes increase both the challenge and the potential spoils, creating a simple risk-reward relationship: spend something valuable, accept a more demanding run and receive something better if you succeed.
That relationship becomes especially important at the Mythic tier.
Players do not casually throw Mythic Tributes into every run. They are exactly the sort of resource people save for the right character, difficulty and farming session because the expected payoff can be extremely valuable.
Which makes a boss animation bug considerably more expensive than it sounds.
If an ordinary dungeon boss freezes, you lose a few minutes.
If Longtooth freezes after accepting a Mythic Tribute, you may lose the ticket as well.
This Is Not Diablo 4’s First Undercity Tribute Problem
Unfortunately, this is also not the first time players have reported the Undercity consuming Tributes without delivering what they expected.
Back in April, we covered players completing Undercity Tribute runs and receiving almost nothing. One Mythic Tribute run reportedly ended with a single blue item, while another player said an Armaments Tribute produced literally no loot.
Then in July, the problem became even stranger. We looked at Undercity bonus chests that could consume Tributes and open completely empty. Players also reported Mythic Armaments chests refusing to open despite apparently meeting their requirements.
Those older issues may not be technically related to the current Longtooth reports.
But they create a larger confidence problem around the same system.
Players need to know that when they spend a rare Tribute, the reward pipeline is reliable.
Longtooth Has Had Bugs Before
The boss itself also has some history.
Blizzard has previously fixed an issue where Longtooth could temporarily become invisible during a particular attack. That does not establish any connection to the current death-animation problem, but it does show that the encounter has required technical fixes before.
The new report appears to involve something different: the game recognizes enough of the boss's defeat to stop normal combat progression, but not enough to finish the encounter and release the rewards.
That is a particularly nasty category of bug because the player has already done everything correctly.
You entered the activity.
You spent the Tribute.
You completed the objective.
The game simply forgot the final verb:
pay.
There Is No Obvious Workaround Once the Tribute Is Spent
The September report also demonstrates why this bug is difficult for players to protect themselves against.
Teleporting away and returning did not fix Longtooth.
There is no reported method for reclaiming the Tribute from the run.
And unlike a bad random drop, this is not something another five minutes of farming necessarily replaces.
The only cautious advice at the moment is therefore frustratingly simple: be careful with Mythic Tributes until we know whether the Longtooth problem is isolated or reproducible.
That does not mean everyone should stop running the Undercity. Two reports do not establish a widespread failure rate, and most players may complete Mythic Tribute runs without encountering anything unusual.
But if you only have one particularly valuable Tribute left, there is no prize for volunteering it to quality assurance.
The Cost of a Bug Matters as Much as the Bug
Diablo IV has bugs. Every large live-service game does.
The interesting question is often not simply how frequently a bug appears, but what the player loses when it does.
A visual glitch costs almost nothing.
A stuck boss might cost several minutes.
A stuck boss after consuming one of the game's more valuable targeted-farming resources can cost substantially more.
That is why these new reports deserve attention even before we know how widespread the problem is.
Longtooth does not need to break every run to become dangerous.
He only needs to eat the Mythic Tribute you were actually saving.
