What is the Dark Citadel in Diablo 4?

The Dark Citadel is a massive and mysterious structure located deep within the heart of Nahantu. It serves as a monument to the First Khazra and represents one of the most difficult co-op raids introduced in Diablo 4. This raid marks a new era of endgame content, where players must team up to overcome three distinct wings, each filled with tough challenges and powerful enemies, before reaching the final boss.

Unlike traditional dungeons, the Dark Citadel requires more than just slaying enemies quickly. Players will need to collaborate and coordinate, as each wing introduces unique mechanics that demand teamwork and strategy. Simply defeating foes won’t be enough; solving complex challenges is crucial to progression.

Why Should You Compete in the Dark Citadel Raid?

The Dark Citadel is more than just a difficult raid—it is the pinnacle of endgame content in Diablo 4. It pushes players' builds, focus, and teamwork to their limits. However, the rewards are equally impressive. Those who conquer the Dark Citadel will be granted access to treasures and rewards unlike anything else in the game, making it well worth the effort.

Beyond the loot, this raid's cooperative nature encourages teamwork, communication, and camaraderie. It’s the perfect opportunity to bond with your friends—or make new ones—as you tackle challenges together, much like the old days of multiplayer gaming.

Who Can Access the Dark Citadel?

The Dark Citadel is open to all players who have reached the maximum level of 60. However, it’s important to note that this raid cannot be tackled solo—you need a minimum of two players to participate. The raid's difficulty scales with your world tier, and while having a great build and high Paragon level will make things easier, it’s not a strict requirement for attempting the lower difficulties. Nevertheless, for the highest world tier—Torment 4—you’ll need both a solid build and a well-coordinated team to succeed.

What is the Dark Citadel in Diablo 4?

The Dark Citadel is an enormous structure located in the depths of Nahantu, serving as a tribute to the First Khazra. This raid is a brand-new type of endgame content in Diablo 4, designed for cooperative gameplay. Players must form teams to venture through three distinct wings, overcoming challenges and defeating formidable enemies until they reach the final boss of the raid.

New mechanics have been added, meaning that simply defeating enemies as fast as possible won't be enough. Each wing of the Dark Citadel requires at least two players to cooperate and navigate through the raid’s various puzzles and unique combat scenarios.

Why Should You Compete in the Dark Citadel Raid?

As the pinnacle of endgame content, the Dark Citadel will test your build, teamwork, and patience like never before. However, the rewards you’ll earn from completing the raid are unmatched, offering exclusive items and gear not available in any other content.

Additionally, the cooperative nature of the Dark Citadel allows players to bond with friends, strengthen communication, and perhaps even make new allies. It’s a perfect blend of challenge and camaraderie, reminiscent of the social aspects of earlier Diablo games.

Who Can Access the Dark Citadel?

The Dark Citadel is accessible to all players who meet the basic requirements, except for those who wish to enter solo, as it is designed strictly for team-based play. To enter the raid, players must reach the maximum level of 60. However, simply reaching level 60 will not be enough to guarantee success in this challenging raid. A strong build and a high level of Paragon will be key to competing, especially on higher difficulties like Torment 4.

Where Can You Find the Dark Citadel?

The Dark Citadel Raid is located in the newly added zone of Nahantu, which was introduced with the Vessel of Hatred expansion. However, players must meet certain prerequisites to access the raid, such as completing the necessary introductory quest and reaching the required level.

Once the raid is unlocked, the Dark Citadel can be accessed directly through the in-game map. Additionally, the raid is featured in the newly implemented Group Finder tool, which allows players to quickly team up with others for cooperative activities.

---

Is the Dark Citadel Only Available for Co-op?

Yes, the Dark Citadel is strictly designed for cooperative gameplay. It requires a group of two to four players to participate, and solo play is not an option. The recommended group size is four, as this provides the optimal balance for dealing with the raid's numerous enemies, solving complex puzzles, and navigating the various paths that separate the wings of the raid.

While there have been rumors about a potential single-player version of the Dark Citadel that would utilize a Mercenary as the second player, this is unlikely to happen. The reason is that controlling mercenaries to complete the puzzles in the raid would be too challenging, making solo play impractical for this particular content.

Party Finder

In addition to the Dark Citadel Raid and other new features, the long-awaited Party Finder has finally been introduced into the game. This tool is incredibly useful for activities where playing with a group brings significant benefits to all participants, such as farming tormented boss rotations or participating in group-specific content like the Dark Citadel, which requires at least two players.

The Party Finder can be accessed in multiple ways, providing flexibility to players. It can be reached quickly through the in-game map, the main game menu, or even the emote wheel. It offers a wide range of functionality, from assembling teams for nightmare dungeons to gathering players for specific wings of the Dark Citadel. It’s also ideal for players looking to group up for tormented boss rotations or farming legendary aspects for the Codex of Power.

Mercenaries in the Dark Citadel Raid

In the Dark Citadel, mercenaries play an important support role, supplementing the team’s efforts in two primary ways:

• For the group leader, mercenaries can be summoned to assist actively in battles, providing both combat support and reinforcing the player’s stats and skills.
• For the other group members, mercenaries function as reinforcement aids, offering stat support under certain specific circumstances, referred to as opportunities.

As players approach the later stages of the raid on Torment 4 difficulty, maximizing the use of mercenaries will be essential. Players will need fully optimized builds with best-in-slot gear and maxed-out paragon boards to stand a chance at success in this extremely challenging content.

---

Dark Citadel Difficulty

Although the Dark Citadel is challenging on its own, the difficulty of the raid scales with the world tier, starting from Torment 1. Each wing of the raid increases in complexity and difficulty, with each subsequent wing being more difficult than the previous one. Along with this increasing difficulty, the rewards also improve, allowing players to earn more Citadel Coins as they progress through the raid.

Comparison Between Dark Citadel and Other Activities

In comparison to other endgame content in Diablo 4 that typically requires a key-type item for entry—such as Nightmare Sigils, Infernal Compasses, or the Artificer's Stone—the Dark Citadel raid stands apart as it does not require any special item to enter. This makes the raid more accessible to players, as they can dive right into the challenge without needing to gather specific resources.

For other dungeon-based content, the difficulty is often determined by the world tier, with items like Nightmare Sigils dictating the challenge. However, in the Dark Citadel, the difficulty is tied directly to the wings of the raid, which scale with the world tier. As you progress through the raid’s wings, the complexity of enemies, bosses, and puzzles also increases significantly.

Unlike many other game activities, the Dark Citadel cannot be brute-forced by just focusing on high damage output. Each wing contains powerful enemy packs, elites, and bosses that require strategic play and coordination. Furthermore, the raid includes intricate puzzles and mechanics that must be tackled as a team, such as reflecting boss projectiles or interacting with the environment to progress.

---

Dark Citadel Wings

The Dark Citadel raid is divided into three unique areas, known as wings, each with its own set of bosses, puzzles, and rewards. The wings can be completed individually, and once one is completed, the progress is saved for each player in the group. This means that players can complete the wings at different times without any penalties or restrictions, allowing flexibility in scheduling raid sessions.

---

Dark Citadel Raid Bosses

Based on the limited information available so far, we have identified four of the First Khazra raid bosses in the Dark Citadel:

• Shredder
• Pulverizer
• Breathtaker
• Trampler

These bosses are said to have unique mechanics and are expected to provide a significant challenge to even the most experienced players. As more information is released, details about their abilities and strategies for defeating them will become available.

Dark Citadel Boss Mechanics

As mentioned earlier, relying solely on power and damage to quickly defeat bosses will not be enough in the Dark Citadel. Cooperation between group members is crucial, as each boss comes with its own set of unique mechanics. Every wing requires players to split up, face different enemies, and interact with the environment to solve complex puzzles and overcome challenges.

One of the boss mechanics introduced so far is projectile reflection. In this case, one party member must collect an item that allows them to reflect a projectile thrown by the boss back at it. This mechanic temporarily staggers the boss, providing an opportunity for a full attack from the entire party.

---

Dark Citadel Rewards

In addition to the usual loot from defeating mobs and elites, completing a wing of the Dark Citadel rewards players with exclusive items and currencies. One such reward is the Scroll of Restoration (also known as the Retempering Scroll), which gives players one final chance to upgrade a damaged item into a best-in-slot (BiS) item. However, this scroll can only be used once per item, and once the tempering rerolls are complete, the item becomes irreversibly locked.

During your journey in the Dark Citadel, you can also obtain a Weekly Cache containing unique items like cosmetics and valuable materials. Don’t forget to claim this cache each week to get exclusive rewards!

---

Citadel Coins

One of the most important types of currency in the Dark Citadel is the Citadel Coins. These coins are a unique form of loot that can be used to purchase exclusive items from the Citadel Vendor.

---

How to Obtain Citadel Coins?

You can earn Citadel Coins by defeating almost any enemy within the raid. Similar to other materials and currencies, these coins are automatically stored in your "Stats and Materials" tab. However, unlike other currencies, Citadel Coins are non-tradeable and must be spent within the Dark Citadel.

---

What Can You Spend Citadel Coins On?
At the Citadel Vendor, players can use their coins to purchase a variety of rewards, including:

• Crafting Cache, Gem Cache, and Gear Cache
• Cosmetic items
• Exclusive Scrolls
• Elixirs & Incenses

The majority of these items are exclusive to the Citadel Vendor, meaning that playing through the Dark Citadel is essential if you want to acquire these powerful and rare rewards.

Best Builds for the Dark Citadel Raid

Before diving into the best builds for the Dark Citadel, it’s important to understand that this raid is designed to challenge even the most powerful players, especially on Torment 4 difficulty. Your build will need to focus on both single-target damage for bosses and AoE damage for the waves of enemies that attack from every direction.

In addition to maximizing damage, survivability is key. Players will need high life pools and maxed-out resistances to mitigate incoming damage. Utilizing unique items like Tyrael's Might or incense to increase resistances will be essential for staying alive in the raid’s toughest moments.

Here are some of the best builds for the Dark Citadel:

• Lightning Spear Sorcerer: One of the top builds in Season 5, this build remains powerful in Season 6 and excels at melting enemies with high damage output.
