Many players may feel familiar with this activity introduced in Diablo 4 Vessel of Hatred expansion - Kurast Undercity. It served as a part of Diablo 2’s third act, and has been changed into a fast-paced dungeon which shares much similarity with Greater Rifts in Diablo 3.
Players are needed to step into the core area of Undercity, slay mountains of monsters until the last boss make appearance. After completing a series task, you are available to embrace tons of rewards.
Broadly speaking, Kurast Undercity owns the identical mechanism with Nightmare Dungeon, but the rewards it offers are totally different. By advantage of Tributes and Bargains, you can access to farm Aspects and certain Affixes. And if you are desperate for those overwhelming items in Diablo 4’s endgame, then Kurast Undercity is a great place to take part in.
This article mainly details the way to unlock and finish Kurast Undercity, and the corresponding rewards that are on offer for you.
There is a post-campaign quest chain named “Deeds of a Champion,” which is designed to lead your way to complete most of Diablo 4’s endgame activities. And you will be given a task to slay Terror of Five Hills. Head to Spirit Brazier in town and to start this mission.
Once this quest being successfully completed, it comes the time to enter Kurast Undercity and kick off your new adventure at your pleasure.
The structure built in Kurast Undercity is kind of identical to Diablo 3’s Greater Rifts. This dungeon is separated into three events, and two of three are time-limited. There are three District Bosses in Kurast Undercity in total, and they are Alia, Kurast’s End in Ziggurat District, Yoche, The Golden in Temple District and Longtooth, The Wretched in Caves District, respectively.
Before you kick off, open the map and get a deep known of the layout. You’ll find out a series of icons scattered throughout Kurast Undercity, which represent those optional events or monsters. Completing the required quests or slaying enemies will award you extra time to complete those two events with time limitation.
Players are awarded an Attunement once the corresponding quests being completed. After making clear of most of the dungeon, you are surprised to see that you have already reached Attunement IV, even if some quests are still unfinished.
Braziers that scatters across the tile consists the main source of time in this dungeon. And they can also decrease your skill cooldowns. So don’t worry about wasting your ultimate skills.
Heading to the other side and making a communication with Exit Portal helps to stop the time.
After completing two floors, you are available to enter the third level - a boss arena. This is a battle without a time limit. You can employ the same approach which assists you in dealing with bosses in Nightmare Dungeons. Specifically, run away from the boss’s AoE attacks, use potions when HP remains low, and try to stagger the boss to offer yourself a DPS window for a moment.
Extending Time and increasing the amount of Attunement are two vital points to complete Kurast Undercity activity. At the first phrase of the game, you may be stressed because of the time limit. So make sure to get a deep known of each mechanic in the dungeon and distribute your time wisely.
One of the vital gameplay mechanics come to its afflicted monsters and structures, which offers your time extension bonuses after being slayed. You can check out the particular location by looking at the orange hourglass icon on the map. Based on the type of afflicted monsters and structures, the time extension provided will also vary. Here lies some details for your reference:
You will be awarded a chest that full of rewards after killing the boss. It is noticeable that most of the rewards are under the influence of Tributes and Bargains.
Kurast Undercity provides no unique rewards, in essence. Typical rewards such as some Legendary items, possibly Runes, will drop from boss’ chest. And plenty of your rewards come from Tributes, a consumable used to provide Spirit Brazier before the game kicks off. But later, you can change your rewards with Bargain, which is aimed to modify all item types dropped from reward chests.
Tributes are concluded into onetime consumables, which can be sacrificed at Spirit Brazier to make a deal for new chest rewards, ranging from Runes, Ancestral gear, to Mythic Uniques. Moreover, Tributes can also enhance the drop rate of Mythic Uniques greatly.
Tributes are divided into disparate rarities, each with its subtypes, and you can get them in most of content in Diablo 4 DLC, containing Nightmare Dungeons, Pit runs, and Helltide chests. Moerover, Season Journey and “Deeds of a Champion” quest chain also serve as great channels to get them.
Bargains serves as the payments paid to Spirit Brazier to modify Kurast Undercity for further progression. Offering Crafting Materials, Diablo 4 Gold, or Obols to Spirit Brazier and helps to modify the content kept in the chest and what Affixes are on the items.
That’s the relevant introduction of Kurast Undercity in Diablo 4 Vessel of Hatred expansion. In short, it’s a complex activity that requires a lot of hard work to complete. Thanks for reading.
Since Spiritborn class launched, Thorns build has been a core build, providing reliable damage output for multiple seasons, making it ideal for clearing dungeons or slaying bosses, so that you can have extra chance to farm more Diablo 4 gold.
With the arrival of the new unique item, Balazan's Maxtlatl, in Season 9, Thorns Spiritborn build has become even more powerful thanks to its thorn damage-related properties.
So how can you build on this gear's benefits and optimize your build to more effectively farm bosses and earn resources in Season 9? We'll explain.
As the core piece of gear that makes Thorns Spiritborn build even more important in Season 9, Balazan's Maxtlatl pants convert your thorn damage into poison damage to nearby enemies, and the poison damage increases with each use of thorns.
From this foundation, you can combine other core Spiritborn skills with reliable gear to create a powerful Thorns and Poison build that deals massive damage to your enemies - in fact, these pants are also the core of other popular Spiritborn builds.
To obtain this item in Season 9, you can complete world events or clear Nightmare dungeons on Torment difficulty, or more specifically, farm the bosses Urivar and Varshan.
After equipping Balazan's Maxtlatl, you must always stand within Mystic Circle when utilizing this build to effectively deal damage.
This is because, when paired with Jaguar Primary Hall, your Mystic Circle will essentially always deal double damage, bringing the total damage output of the entire build to an astonishing level.
In short, in Season 9, the only thing that really matters for this build is Spirit Hall and Paragon board selection; gear and skills should be based on standard configurations. We'll explain this further.
Spirit Hall is a class-specific mechanic for Spiritborn class, allowing you to designate primary and secondary spirit guardians. The primary spirit guardian affects all of your skills, while the secondary spirit guardian grants you additional passive effects.
For Thorns Spiritborn build, Jaguar Primary Spirit Hall is essential. This mechanic transforms all of your skills into Jaguar skills, and each time you deal 15 direct damage to an enemy with a skill, you gain an additional attack.
The secondary Jaguar Spirit Hall increases your maximum Ferocity by 1, and grants an additional Ferocity for each kill or boss damage.
For this reason, the essential Spiritborn skill for this build is Quill Volley. This skill hurls five feathers at enemies, piercing them each time, with each feather dealing 26% damage.
This, combined with the frequent feather and the extra attack opportunities provided by Jaguar Primary Spirit Hall, allows you to rack up significant damage in combat. You can also further enhance Quill Volley in the skill tree.
Other skills worth adding include:
Besides Balazan's Maxtlatl, the first piece of gear I recommend for this build is Razorplate. This universal chest armor grants you thorns, giving them a 10% chance to deal 100-200% increased damage.
Additionally, you'll need to equip some gear with runes or gems to further enhance their power. Based on this build, we recommend the following gear:
As the most important seasonal mechanic of Season 9, Horadric Spells and Jewels can provide additional benefits to most builds, provided you choose and equip the ones that best suit your style.
Horadric Spells:
Horadric Jewels:
As you know, mercenaries are a mechanic introduced in Diablo 4 Season 6 that allow you to select two mercenaries to assist you in battle, so they can also be added as part of builds.
The best mercenary build for this build is to have Raheir as your main companion and Varyana as the reinforcement, unlocking the following abilities for each:
Raheir:
Varyana:
We hope this information helps you accumulate more resources before the end of Season 9 so you can prepare for Season 10, which launches at the end of September! Thank you for reading!
Diablo 4 Season updates typically mean not only more new playstyles to try, but also the opportunity to use your creativity to create even more powerful builds that better suit the current season's mechanics.
The biggest contributors to this are usually the added seasonal powers and unique items granted to each class each season, and Season 10 is no exception.
The seasonal power of this season is Chaos Perks, and the unique items each class receives are:
Druid, a class that has been relatively underwhelming for several seasons, is expected to gain additional build crafting possibilities in Season 10 thanks to this new item, giving it a new advantage.
With this in mind, this time we'll introduce Storm Raven Build centered around the new Druid item, Kilt of Blackwing.
This new unique item can also be utilized as Chaos Armor in Season 10, so while it's a unique pants item, you can actually equip it in any slot this season.
The most important combat benefits of this item revolve around Raven. In addition to the basic affix effects, it increases the damage dealt by ravens by 60-100%, allows them to transform into alternate forms, activate companion skills, and even has a chance to summon more ravens.
Beyond the benefits provided by the core gear Kilt of Blackwing, to successfully craft and utilize this build, you'll need to farm more XP and Diablo 4 gold to ensure your character's smooth leveling and survival, and try to provide more bonuses to your ravens.
Ravens are essentially a companion skill for Druid, and the core concept of Storm Raven build is to leverage Kilt of Blackwing's Raven buffs, combining them with skills, gear, and other key mechanics to make their effects even more powerful.
As one of the key features of Season 10, Chaos Perks are worth adding to any build. However, the number of perks is enormous, and the power you can equip in a single battle is limited, so you need to choose carefully.
For a Storm Raven build, we recommend prioritizing the following perks:
For this reason, you must ensure your first attack triggers poison, then utilize Raven's Hover to attack more targets. Finally, Power Siphon allows you to deal more damage with your core skills.
If seasonal Chaos perks are the icing on the cake, then skills are the foundation of any build. The first essential element of a Storm Raven build is naturally Ravens. Their abilities include:
With this, combined with Kilt of Blackwing, your build's damage output is essentially guaranteed. The next skills you should add include:
Furthermore, you'll want to minimize your ability cooldowns to ensure your build remains effective throughout combat. If your cooldown is full, you can use Cataclysm unlimited times - keeping it active at 100% is key for this build.
Besides the core item, Kilt of Blackwing, the key to adding gear to this build is, as we've already mentioned, minimizing your cooldowns as much as possible.
In general, once your Cataclysm cooldown is at 100%, feel free to swap out gear for increased DPS, increased survivability, or whatever bonuses you desire.
For this reason, we recommend prioritizing the following gear:
Shroud of False Death:
Tassets of the Dawning Sky:
Another essential Legendary Aspect is Stormcrow's Aspect, which increases the lightning damage dealt by raven by 60-100%. Raven skill itself deals full damage for half the duration, and stuns enemies within range.
In fact, the gear options for this build are quite extensive. Besides the highly recommended ones listed above, you can freely farm and equip other builds based on your preferences and combat style.
Note that the above crafting plan is based on a trial of content from 2.4.0 PTR. There may be some minor differences after Season 10 officially launches. You'll need to decide how to utilize this build based on future Diablo 4 adjustments.
That's all we've covered. We hope this helps you embark on your Diablo 4 Season 10 journey. Thank you for reading.
Due to varying season mechanics and the effectiveness of new items, the most reliable class options fluctuate between each Diablo 4 season. A class that fell out of favor one season might become a popular choice in the next.
Take Druid, for example. Several nerfs to the game meant few players initially chose it when it launched in Season 9. However, the recent patch has revived its popularity in the middle of Season 9.
After the launch of 2.4.0 PTR, based on current performance, Druids are expected to maintain their dominance in Season 10 and offer multiple reliable builds. This is likely because of the addition of new unique items.
Next, we'll analyze the reasons why Druid has dominated 2.4.0 PTR, focusing on the unique item, Kilt of Blackwing.
This item, an exclusive Druid unique item added to PTR (Season 10), initially has the following base affixes:
Adding to this, these unique pants increase the damage dealt by ravens by 60.0 - 100.0%, allowing you to transform into other forms or activate your companion's abilities, summoning more ravens to attack nearby enemies.
Notably, if you summon ravens with this item, there is a chance to inflict Unkindness for 10 seconds, increasing the number of ravens you can summon to three for the duration.
In the past, when utilizing Companion Druid build, the two key components were ravens and wolves, making up the "companion" portion of the build. While wolves previously received a damage boost through Storm's Companion-specific affixes, ravens never received the same buff.
To address this long-standing shortcoming and to substantially enhance both Druid and related builds, Diablo 4 is adding Kilt of Blackwing to enhance the raven elemental's presence and allow you to deal more damage with these builds.
If you're considering using the new effects provided by Kilt of Blackwing with a Companion Druid build on PTR or in Season 10, you might be concerned that both it and Storm's Companion are unique pants, making them incompatible.
While this would have been a problem in other seasons, Season 10 new Chaos Armor mechanic effectively mitigates this issue - which is why Companion Druid build has existed for so long, while Kilt of Blackwing hasn't been added until now.
Chaos Armor is a more powerful version of the unique armor added in Season 10. One of its features is that all Chaos Armor items can appear in any inventory without specific restrictions, giving you more possibilities for using unique items.
So, in 2.4.0 PTR, you can utilize both items in a single build. For example, in addition to pants, you can also equip Kilt of Blackwing on boots or gloves.
Of course, to obtain these items, you must repeatedly farm the bosses that drop them. Although PTR may provide them directly to you, after Season 10 begins you must obtain unique items and sufficient Diablo 4 gold on your own.
In short, due to the unique nature of Chaos Armor's mechanics, you can equip both unique items as a Druid in Season 10, doubling their effectiveness and making them even more powerful, giving Druids advantages unmatched by other classes both in PTR and in the new season.
As a reminder, all Chaos Armor expected to be available to Druids in Season 10 includes:
Class Exclusives:
General Uniques:
Without a doubt, Companion Druid build is a top priority in PTR and even in Season 10, thanks to the reliable buffs provided by Kilt of Blackwing.
However, assuming no additional significant nerfs are made to Druid after Season 10 officially launches, the following builds will remain reliable:
Of course, different builds have different requirements for skills, gear, Spirit Boons, and more, and you'll need to craft them accordingly to maximize their effectiveness.
More importantly, in PTR, you can also farm new enemy types to get seasonal Chaos Powers, which are also an essential part of crafting and utilizing the new builds. You can also enhance your builds by upgrading Chaos Powers.
Overall, if you're aiming for quick dominance as a Druid in 2.4.0 PTR or Season 10, Companion Druid build is the better choice, as the new unique items are specifically designed for that purpose.
Alternatively, you can develop and experiment with a wider range of builds based on Kilt of Blackwing before PTR ends, incorporating your own unique playstyle. If you find some of them work, you can put them to the test before Season 10 launches!
That's all for this introduction. The new unique items obtained by other classes also have significant new uses, if you have time, you can also test them out in 2.4.0 PTR!
Since the game's launch, Diablo 4 has added seasonal powers to almost every season. While their names and specific functions vary, they essentially all provide new combat benefits in a season-specific manner.
Season 10, the final season of 2025, is expected to launch on September 23rd. A month before that, Diablo 4 2.4.0 PTR will be available from August 19th to 26th, allowing you to preview and test the main gameplay of Season 10.
This PTR will allow you to experience the power of Season 10 new Chaos Perks in advance and, combined with them, craft new builds to farm Diablo 4 gold in new dungeons and in-game events in a seasonally specific way.
With this in mind, we'll introduce all Chaos Perks that will appear in the game and their combat effects.
Chaos Perks, also known as Chaos Powers, are divided into general and class-specific types based on their stats. They rank on four rarity levels: magic, rare, legendary, and unique.
There are three general powers of each rarity, and every class has one specific Chaos Perk of each rarity, for a total of 36. Regardless of your playable class, you have access to 16 powers.
Equipping Chaos Powers activates their effects without attaching any other items. However, it's important to note that you can only equip one unique power and three non-unique powers per battle, and some perks may offer advantages as well as disadvantages.
However, by choosing perks wisely, they can be used in conjunction with your class skills and gear to craft new builds tailored for Season 10.
In all Season 10 updates, Chaos Rift is a seasonal event. These rifts will randomly appear throughout Diablo 4, including dungeons. Killing the monsters that spawn from these rifts will reward you with Chaos Perks, as well as special rewards like Chaos Armor.
Once you've earned Chaos Perks, you can consume seasonal currency to upgrade them, up to level 10. However, upgrades only increase the inherent stats of your powers and don't grant any additional effects.
The exact currency name and the required amount per level won't be fully known until 2.4.0 PTR or even the release of Season 10. But honestly, this won't ruin your PTR experience.
Here are all 12 general Chaos Powers and their effects, listed below by rarity:
Magic Chaos Perks:
Rare Chaos Perks:
Legendary Chaos Perks:
Unique Chaos Perks:
Specialized powers add benefits to your character based on the characteristics of their class, making them more targeted than generic ones.
Barbarian
Druid
Necromancer
Rogue
Sorcerer
Spiritborn
That's all for you, but the number of powers and their specific effects are subject to change after 2.4.0 PTR or Season 10 launches, so be sure to stay tuned for any game updates!
Perhaps because of the delay of the second DLC until 2026, Diablo 4's overall performance this year has been rather mediocre, seemingly lacking the appeal of other popular ARPGs. However, the reality is that no game can avoid this phase.
As the final season of 2025, Season 10 is expected to launch on September 23rd. The gameplay should remain largely the same as before: buffs from seasonal powers or items, new dungeons and events, and various minor optimizations.
While the gameplay isn't significantly different, there are still some subtle differences. Without a thorough understanding of these, it's difficult to fully enjoy Season 10. Therefore, it's worth checking out this guide to get your hands on 2.4.0 PTR.
PTR will launch on August 19, 2025, and will run until August 26th. Next week, in addition to previewing Season 10 content, you can also experience new changes coming to Vessel of Hatred.
2.4.0 PTR is expected to highlight Chaos Amor, Chaos Perks, and a revamped Infernal Hordes from Season 10. The game will continue to refine the content based on your feedback and that of other players participating in PTR, aiming for an even better Season 10 in September.
As the name of Season 10, Infernal Chaos, suggests, the first feature of this season is the addition of several Chaos-centric seasonal content, including new Chaos Perks and Chaos Armor items.
Chaos Perks, like Horadric Powers and Boss Powers from the previous two seasons, will provide new ways to gain combat benefits and will be available in four tiers:
You can expect to equip three non-unique perks and one unique perk per battle, and the maximum number of perks that can be obtained per class is 16.
As for Chaos Armor, it's an item that adds to your Chaos Perks and offers more combat possibilities. They're enhanced versions of existing Unique items. If you already own a Unique item, it can be used directly as Chaos Armor in Season 10.
Therefore, Chaos Armor should remain the same as before, dropping from certain bosses along with Diablo 4 gold. It's worth noting that the unique items added to each class in Season 10 are also Chaos Armor:
As one of Diablo 4's most significant endgame events, Infernal Hordes has become not only popular but also a valuable resource farming location since its introduction in Season 5.
Season 10 is expected to feature updates to Infernal Hordes, which will refine the event's gameplay and provide more value by adjusting offerings and base monster counts.
For example, the game will grant you an Infernal Offering upon entering the event, instantly igniting embers to inject a burst of fire into your battles, allowing you to clear enemies more quickly.
Infernal Hordes will also feature Chaos Monsters and Chaos Waves based on Chaos mechanic. Killing Chaos Monsters grants you special buffs, while Chaos Waves increase the difficulty of subsequent waves, giving you the opportunity to farm more loot.
Previously in Infernal Hordes, Fell Council was the final enemy type you encountered. In PTR and the official Season 10, one council member will be designated as the council speaker and gain enhanced skills.
Adding to this, you can also play the newly added Fleeting Hordes in PTR. After completing its four waves of attacks, defeat two Fell Council members before consuming Aether to redeem rewards.
In addition to the existing Fell Council, Season 10 will also add Bartuc, the Vizjerei Warlord, as the final boss of Infernal Hordes. If you enter Infernal Hordes as a group, every member must consume Aether to fight him.
Another new feature worth keeping an eye out for is the seasonal Chaos Rifts, which randomly spawn monsters and demons in Helltides and Nightmare Dungeons. Completing these events may reward gold, XP, gems, and Chaos Armor.
If you're lucky, you might encounter Mythic Chaos Rifts, and completing these events might even grant you Mythic Uniques.
2.4.0 PTR is expected to be available in the major regions of North America, Europe, Korea and Japan, South America, and Australia. And as with most previous PTRs, you can earn additional PTR boosts through vendor Mrak.
After creating a new PTR character, you can find Mrak near the main waypoint in Ked Bardu. He will provide segmented boosts for testing specific items. All available 2.4.0 PTR boost content includes:
Crafting & Materials
Equipment
Paragon
Progression
Seasonal
Expect further changes to the above content after Season 10 officially launches, which will also include new Season Journeys, Blessings, and Reliquary Battle Pass. While everything will be finalized with Season 10, until then, enjoy 2.4.0 PTR!
Thanks to the rapid development of social media, it's now possible to communicate with the creators of your favorite games directly! Some games even host exclusive panel discussions to gain a deeper understanding of player opinions.
For Diablo 4, this event is Sanctuary Sitdown - or, until August of this year, you might have been more accustomed to calling it Campfire Chats.
Regardless of the name, the two events' purpose remains to provide a platform for communication between the development team and players.
So, what is the purpose of this Sanctuary Sitdown, and how will you participate? What will it reveal about the future development path of Diablo 4? We will provide you with an introduction and speculation.
The event will begin at 11:00 AM PDT on August 14, 2025. It will feature a host, members of Diablo 4 development team, and players joining Sanctuary Discord to engage in discussion and answer questions from players in the channel.
This event is expected to focus on discussing and answering questions about Season 10 and its PTR. If you're interested and would like to ask the developers questions by participating, please follow these steps:
It's important to note that the specific content of Season 10 that will be discussed during Sanctuary Sitdown is currently unknown, and the players' questions that will be answered will be random, making the duration of the event uncertain.
While this isn't the first time Diablo 4 has held a Sanctuary Sitdown, developers are more accustomed to using Campfire Chats to communicate with you before the launch of a new season in the past.
Campfire Chats are typically broadcast live on Twitch or YouTube, allowing you to watch the live stream or replay it even if you don't have an account. However, due to platform changes, Sanctuary Sitdown on Discord not only requires a platform account but also doesn't offer replays.
This means that if no participants record the livestream content, you won't be able to view the interview content without participating in Sanctuary Sitdown.
As for the changes in live content, Campfire Chats will be more focused on "interviews," allowing the development team to directly inform you about changes related to the new season and PTR, such as possible new content and changes to Diablo 4 gold drop rates.
However, Sanctuary Sitdown will clearly place greater emphasis on communicating with you and other players, answering valuable player questions to share Diablo 4's plans and development schedule for the new season, allowing you to feel more engaged.
To be honest, this change in communication format has both advantages and disadvantages. On the positive side, Sanctuary Sitdown can raise the barrier to entry and ensure that players who participate are genuinely interested in game development.
This will ensure that questions received during the event are more targeted and valuable, avoiding interruptions from "guest" users and improving the effectiveness of the event.
However, the increased barrier to entry may also discourage some players from participating, and the inability to replay the event livestreams will deprive players of sufficient access to the new season's changes.
Given the mediocre performance of recent seasons, you might even consider this a "cop-out" strategy for Diablo 4: while avoiding more public feedback, the selected questions may already be predetermined.
While the livestream hasn't yet begun, it's clear that Season 10 will be the focus of discussion. However, the change in format also means that the season may lack sufficient content for developers to discuss, necessitating the use of Q&A to fill the time.
Currently known information about Season 10 primarily includes Chaos Powers, Infernal Hordes update, new pets, and more IP collaborations announced in the 2025 roadmap.
Therefore, we anticipate that Season 10 will not differ significantly from the previous two or three seasons in terms of overall season mechanics, continuing the same formula of new season power, dungeon updates, and other new events.
As the final Diablo 4 season in 2025, you might have hoped that S10 would deliver truly compelling new content, like S6, which launched at the same time last year, such as a new class or dungeon.
However, Season 6 was able to do so primarily because it launched alongside the first DLC.
Considering that the second DLC will launch sometime in 2026, likely not far from the end of Season 10, a lackluster performance for Season 10 as a transitional season is entirely acceptable.
In fact, rather than innovation, addressing long-standing shortcomings is more important for the current Diablo 4 regular season, such as increasing loot drop rates, further improving class balance, and adding player leaderboards.
Overall, we expect Sanctuary Sitdown to offer only a few details about Season 10 and PTR, with no surprise announcements expected unless they discuss the development progress of the next DLC.
However, if you have the time, you can definitely participate. While there are some requirements, it's not difficult to do. If your question is selected, it's a great experience! Good luck!
