Diablo 4 Season 15 has already run into quite a few issues during its first week, but this week has also brought plenty of content worth exploring. With so many classic elements returning, who would have thought we could challenge Baal in D4 again? Various bugs and unusual interactions have continued to appear, and Blizzard has already released multiple Hotfixes to deal with them.
September 22 Hotfix mainly focused on bug fixes, making it important for players progressing through Season 15 content and directly affecting Season of Hell's Legacy experience.

Next, EZG.com will take a look at what this Diablo 4 Hotfix fixed, along with some of the gameplay changes and hidden content in Season 15.
Uber Tristram
Diablo 4 Season 15 brings back some very recognizable classic Diablo content, and Uber Tristram is one of them. To access it, you first need to collect three types of Primeval Splinters, then place the three Splinters into Horadric Cube to craft Wirt's Lucky Coin.
After that, put Wirt's Lucky Coin into the fountain in Old Tristram to open a portal to Pandemonium Event, where you can challenge the three Prime Evils: Diablo, Mephisto, and Baal.
The problem occurred after Wirt's Lucky Coin was crafted. Some players put Wirt's Lucky Coin into Tristram fountain, only to find that Wirt's Lucky Coin was consumed without Portal appearing, effectively wasting an attempt to enter Uber Tristram. Diablo 4 Hotfix released on September 22 has fixed this issue, so the entire process should now work properly.
Hotfix 4 also fixed an issue that allowed players to gain excessive experience and Diablo 4 items from Prime Evil Council fights, while increasing the loot cooldown for Prime Evil Council. You now need to plan your number of attempts and routes more carefully.
Abnormal Damage
Hotfix also addressed several issues that could cause abnormal damage. Damage-related bugs have been one of the main areas targeted by the repeated Hotfixes released since the launch of Diablo 4 Season 15. Hotfix 2 had already fixed an issue where Rogue's Dance of Knives could deal far more damage than intended.
Hotfix 4 has now addressed a Warlock damage issue. Lesser Demon Bonus upgrade for Fiend of Abbadon could previously cause Warlock to deal unintended damage, so the upgrade was temporarily disabled. After Hotfix 4 fixed the issue, Diablo 4 re-enabled Lesser Demon Bonus.
There was also an abnormal damage interaction between 5-set bonus of Old Mountain Talisman and Diablo 2 Runeword Grief that returned in Season of Hell's Legacy.
Old Mountain Talisman causes Petrified enemies to explode when the effect ends or when the absorbed damage exceeds their remaining life, dealing damage equal to 200% of the absorbed damage.
Grief provides Deadly Strike Chance and Damage to Demons. When the two were used together, they could trigger unintended damage results. Diablo 4 Hotfix has now fixed this issue.
The Butcher
The infinite The Butcher spawn issue came from an unusual interaction involving War Plans in Diablo 4 Season 15. It allowed players to repeatedly trigger The Butcher inside Nightmare Dungeons, theoretically creating infinite spawns.
More importantly, repeatedly killing The Butcher could also reward Mythic Uniques, allowing some players to quickly fill out their Mythic gear.
This exploit directly affected Season 15 leaderboard. Players noticed that some characters had already obtained large numbers of Mythics, or even complete sets, very early in the season. These abnormally obtained items put players competing normally on Diablo 4 Leaderboard at a disadvantage.
Diablo 4 Hotfix has fixed the infinite The Butcher spawn issue. As for whether players who used the exploit will be banned, have their items rolled back, or have the leaderboard reset, we still need to wait for Blizzard's official response.

Seasonal Progress
Another notable issue affected the final reward from Seasonal Reputation. Some players opened Resplendent Cache from the final Seasonal Reputation reward but did not receive Diablo 4 Resplendent Spark they were supposed to get. Hotfix has fixed this issue, which directly affects progress toward Season of Hell's Legacy rewards.
Horadric Cube Materials
Diablo 4 has also fixed an issue where Horadric Cube crafting materials were not properly granted through the corresponding Kurast Undercity tributes. Kurast Undercity tributes can increase rewards for specific types of resources.
For example, Tribute of Refinement is used to obtain Masterworking Materials, while Tribute of Harmony mainly provides Runes. Other Tributes focus on rewards such as Boss Summoning Materials and Unique Items. With the issue fixed, you can now farm Diablo 4 Undercity more effectively for the specific resources you need.
Hidden Content
Season 15 also has some hidden content that players are gradually discovering. Mephisto has entered the game, and defeating it can give you a chance to obtain the new pet Marquis Milky for free.
Diablo 4 Season 15's Runewords also include some interesting mechanics. If you are missing a specific Rune, you can craft it directly through Horadric Cube instead of relying entirely on drops.
For example, if you are missing a Ber Rune, you can use two lower-level Runes and a Grand Topaz to craft it. Runes can also be upgraded through amalgamation. Place five Runes of the same level into it to combine them into a higher-level rune.
Diablo 4 Season 15 is still only in its first week, and our exploration of these new and returning mechanics is far from over. As more players dive deeper into the various seasonal systems, previously undiscovered interactions may continue to appear. For players progressing through the season, Hotfix changes can directly affect current farming methods and gameplay choices.
