Kurast 3000 BA
DIFFICULTY: EASY


Level
Hatred : 60
Terror : 115
Destruction : 120

Location
Act 3: Travincal

There are two variants of this level. Re-roll the map to have a chance of getting another one. You can do so by, for example, changing difficulty.

Lore
This uberlevel is a recreation of the city of Kurast located at the Kehjistani frontier, 3000 years before the birth of the prophet Akarat and during the Mage Clan Wars between the Ennead, Annuit and Vizjerei clans. Kurast, a neutral town allied with the Taan, was seized by the Ennead and used as a necromantic military outpost. Can you destroy the magical fortifications and liberate the town?

Enemies
The town is well defended by armies of skeletons undead. Around the town square you will find the Ennead shadowgate totems, which periodically raise additional skeletons and emit a magical field that grants invulnerability to nearby units. The necromantic army is tended to by a contingent of Ennead Necromancers.

Bosses
Your targets are the Ennead Necromancers spread out around town. They summon more skeletons and cast the powerful Nightmare curse, slowing you down and disabling magical healing.

Reward
On any difficulty, the Ennead Necromancers drop a random Class Charm in addition to their regular drop. There are 7 different Class Charms, one for each character class. You need your Class Charm for other challenges and uberquests.

Island of the Sunless Sea
DIFFICULTY: MODERATE


Level
Hatred : 65
Terror : 115
Destruction : 120

Location
Drifter Cavern (Act 5: Glacial Trail)

Lore
The place where angels watch, once the staging ground of the heavenly host for their crusades into the abyss, is an underground cave miraculously illuminated by sunlight. When the holy legions were defeated and forced out of the dimension by the forces of Hell, a few human worshippers remained behind to stand vigil. But heavenly magic is too powerful for mortals to tolerate for long. The mutated, wretched remains of the human defenders were found and embraced by the mighty Lucion, son of Mephisto.

Enemies
The Island is defended by the demented priests and their escorts of warrior nuns. The nuns wield holy weapons which grant them divine invulnerability if they keep attacking, while the priests conjure the holy spirit in the form of a slow moving wraith projectile which should be avoided at all costs. Near them are Lucion's overseers, the Feyrs, and their unholy Nightmare curse.

Bosses
A short distance from the entrance is Lucion's high priest, Malic, wielding fire spells and a deadly homing chaos bolt. Lucion himself has a powerful poison attack, 50% resistance to all damage and emits an unholy aura that makes nearby enemies invulnerable.

Reward
Defeat Malic on Destruction difficulty to get the Six Angel Bag.

Khalimgrad
DIFFICULTY: MODERATE


Level
Hatred : 70
Terror : 115
Destruction : 120

Location
Infernal Pit (Act 5: Frozen Tundra)

Lore
Heaven. Nirvana. Celestia. Call it what you will. Home of the heavenly host, which almost destroyed the taint on creation that is the mortal plane twice and allowed it to get overrun by the forces of Hell. Far from being the beings of love they are believed to be by the common folk, the angels of the High Heavens present a clear and present danger to Sanctuary. It may be better to strike first.

Enemies
Ethereals are the physical manifestations of common angels. They attack furiously, but when you kill one of them, it shatters, reducing all resistances of other nearby enemies to -100% but inspiring them with righteous zeal. The glowing Orbitals and the Lightwell gargoyles with their deadly poison bolts are impossible for mortals to destroy and should best be avoided. Keep a close eye on the health of your minions: the death of a minion releases its soul to heaven, healing all Ethereals and Avatars. Casting Nightmare or deploying a Void Archon nearby will stop this healing.

Bosses
Zakarum's Avatars watch over the battle on wings of light. They are divine and immortal, but when an Ethereal dies nearby, the backlash temporarily makes them vulnerable, reducing all resistances to 0%. Strike while it lasts, and strike several times, because their divine grace enable them to ignore a percentage of all incoming attacks.

Reward
Defeat Zakarum's Avatars on Destruction difficulty to get the Zakarum's Ear (1/12 chance).

Zakarum's Ear

Tran Athulua
DIFFICULTY: TRICKY


Level
Hatred : 60 (location of a Hatred challenge)
Terror : 115
Destruction : 120

Location
The Twin Seas (Act 2: Halls of the Dead)

Lore
The jungle capital of the Amazon nation, Tran Athulua, is almost impossible to take by land or sea. After a humiliating defeat, a band of pirates hired you to assassinate the high priestesses and plunder the treetop city during the confusion.

Enemies
Tran Athulua is heavily guarded by bow-wielding Amazon warriors, whose numbers and seeking arrows may overwhelm a weaker hero. Beware the jungle snakes: while seldom directly lethal, their debilitating poison will burden you for a long time, slowing you to a crawl.

Bosses
The priestesses of the three elements, Philios, Skovos and Lycander watch over the city and can be distinguished by their heavy armour. They are dangerous targets due to their Phalanx spell and the ability to call an earthquake which deals magic damage based on a percentage of your current health and is therefore nearly impossible to mitigate. Expect to spend most of the fight at a fraction of your health.

Reward
Kill the Pirate at the entrance on Hatred difficulty to get the Elemental Prism.

Fauztinville
DIFFICULTY: TRICKY


Level
Hatred : 80
Terror : 115
Destruction : 120

Location
Stony Tomb Level 2 (Act 2: Rocky Waste)

Lore
After the destruction of the Prime Evils, a new era of peace and prosperity began, eventually evolving into what we call the modern age. Humanity has all but forgotten how to deal with demons. Until out of nowhere an evil force beneath the metropolis of Fauztinville begins to corrupt the machinery and pets, turning them against their masters. Overwhelmed by the assault, the army employs its new experimental time machine to request help from the heroes of the past. Will you answer the call?

Enemies
Fauztinville has fallen under an onslaught of demonically twisted robots and demons bursting from the city's neon signs. Each battle should be straightforward, but beware their various immunities, notably the tri-elemental immunities of Neon Fiends. Summoners should eliminate Harpylisks first to prevent their bouncing blade attack from ravaging their forces.

Bosses
The invasion is led by five warped robots, Alpha, Beta, Gamma, Delta and Epsilon. Find them in the back alleys of Fauztinville and terminate them. If you have trouble finding them, look for dead-end streets and hidden passages through buildings. One of the five requires a teleport skill to access; if you do not have a teleportation spell, use an item with charges of Blink or Jitan's Gate, like the runeword Pax Mystica or the reward charm for the Lord Aldric Jitan uberquest.

Reward
Fauztinville on Destruction difficulty is the only place where you can find the following three Great Runes. These runes are required for the most powerful runewords.

The Triune
DIFFICULTY: HARD


Level
Hatred : 80
Terror : 115
Destruction : 120

Location
The Triune (Act 1: Cathedral)

Lore
The White Temple of the Cult of the Triune. The symbol of the trinity is pervasive throughout their rank and architecture, inspired by their patron saints: Dialon, Bala and Mefis. In truth, these saints of love and beauty were the three Prime Evils wearing a guise of peace, but only the High Priests and Bishop-Templars knew the truth, slowly spreading the Three's corruption through the church and its servants. Each saint had a Bishop-Templar vouchsafing her aspect. Gulag the Black Inquisitor, for Bala. Drider-King Astrogha, for Dialon. And Lucion, Mephisto's own son, for Mefis.

Uldyssian ul-Diomed broke the Templars' armies on the battlefield in his campaign to obliterate the Triune and the Cathedral of Light, even managing to destroy Gulag. Astrogha escaped to some shadowy realm, but Lucion elected to remain, hoping to corrupt Uldyssian. The Son of Hatred sent the High Priest Malic to treat with Uldyssian, but the Edyrem King knew better than to listen. Uldyssian ul-Diomed met Lucion and Malic on the field of battle and banished them, but not before the demon and his priest slew Achillios, the Sword-Corporal of the Edyrem, and Uldyssian's closest friend.

A war of subterfuge erupted following the Edyrem's campaign. With Gulag slain and Lucion and High Priest Malic banished from Sanctuary, Astrogha sought to fill the power vacuum. High Priest Primus had strangely disappeared in the late years of the war, so Astrogha took on that guise and sent High Priest Arihan, along with a troop of Peace Warders, Que-Hagan priests, and Morlu, to try and dispatch of Uldyssian once and for all. Again, the armies were dispersed and the great demons banished.

But where Lucion and Malic had failed, and where Astrogha and Arihan had failed, Lilith had succeeded. Lilith, the Mother of Sanctuary, finally corrupted Uldyssian, and thereafter the Dark Edyrem sealed themselves away. Lilith reestablished the Triune and installed Arihan as the sole High Priest. However, and fortunately for the forces of light, it is said that an aspect of Primus haunts the great temple halls of the Triune, seeking revenge for his usurpation by Arihan.

Enemies
The Triune is defended by a host of powerful constructs and revenants: the ghastly Impaler Archons spitting beams of white-hot energy, the cold Kraken Guards, who will haunt their own dying grounds. The homuncular Primal Clays, and the flaming-but-static Temple Spires which rain down destruction all around them.

Boss
To defeat Arihan, High Priest of the Triune, you must find a way to convince him to fight Primus' Messenger, a strange being sent by Drider-King Astrogha. There are rumors of an even queerer creature possessed by the demon-of-deceit Lilith, that could hold the key...

Cycles
The Triune on Destruction difficulty is the only place where you can find Cycles. There are 9 different Cycles and most of them come in three sizes, with each larger size being more powerful. You can keep multiple cycles in your inventory.

Reward
Defeat Arihan, High Priest of the Triune on Destruction difficulty to get Lucion's Soulstone.

The Unformed Land
DIFFICULTY: HARD


Level
Hatred : 85
Terror : 115
Destruction : 120

Location
Act 5: Harrogath

Once you enter the Hidden Fortress - Unformed Land Level 7, you cannot go back through the stairs.

Lore
The Unformed Land, or Mbwiru Eikura, is the spirit realm that only the Umbaru Witch Doctors can see, through rituals. According to their beliefs, the mortal realm is only a veiled reality of the Unformed Land. They have ritual tribal wars in which they take human sacrifices, only the ones fallen in battle, to be worthy of sacrifice to the gods. The sacrifices are centered upon the life force that flows from the gods that inhabit the Unformed Land to the lesser physical realm that the mortals inhabit.

Enemies
Besides the gods, the Unformed Land is inhabited by other creatures. The first 5 levels are full of ancient elementals that have a ranged attack that does damage in their element, eventually they'll come to melee range. Stay away from any big clearings or keep moving!

Boss
The entrance to the sixth level - Hidden Fortress - is guarded by witches. One you enter, you will see that it is infested with unkillable Ratfinks. There are also Goliaths guards - these gigantic creatures will curse you and deal heavy damage. They can't be killed swiftly, but they are not a huge threat. They are just guarding the area until you reach the king, Terul. After you follow one of the two corridors, you will find a small spot where he is located. Terul was a servant of the mage Zorun Tzin, he was strong, but not overly intelligent, so the fight is pretty simple. He is immune to poison and physical damage, and despite his high regeneration, killing him is fairly easy, compared to his master.

Secret Elemental Runes
On Destruction difficulty you will come by the Elemental Essences and Runestones by killing the elementals there. You can cube them to get the Elemental Runes and Kabraxis' Stone rune.

Reward
Defeat Terul in the depths of the Unformed Land, on Destruction difficulty, to get the Trader's Chest charm (1/4 chance).

Crypt (Act 1: Blood Raven's Graveyard)

Lore

Ureh and everyone within are now trapped between the mortal plane and the Burning Hells, appearing in this world only once every two thousand years, when the shadow of Mount Nymyr falls upon the ruins. Be there.

Enemies
The ghostly citizens are impossible to kill, but they are more than capable of killing you. Keep moving at all costs to avoid the undead hordes.

Bosses
The plazas of Ureh are huge, there is no minimap, the lighting is very dim and the mad King Juris Khan is located at the end of a precarious bridge to oblivion. Please run around like a damsel in a zombie film until you find the narrow ledge leading to the king. Juris Khan brings more minions from beyond the grave, finish him quickly.

Level

Destruction : 120

Location
Pit of Acheron (Act 5: Arreat Plateau)

Lore
You ended the demon invasion of Fauztinville... fast forward another few hundred years. Following a global demon apocalypse, the city is in ruins. Lilith, once banished to the Plane of the Dead, broke free and corrupted the sons of the cosmic dragon Trag’Oul. Weakened by his battle against the angelic and demonic legions at the end of time in the far future, the draconic death god was unable to stop Lilith from capturing and possessing his young. There is no hope for humanity's resistance forces unless these creatures are eliminated. The old time machine was put into action once again... Will you help out Fauztinville a second time?

Enemies
The Howling Spirits materialise directly on top of you when you approach their hiding spots. You have no choice but to take some hits unless you have inhuman reflexes. Defence is very important.

Bosses
The shadowy Dark Star Dragon is one of Trag’Oul's young, twisted and bent to evil. It summons additional Howling Spirits and has a double rotating death beam that will make short work of you unless you seek cover as the beams pass by.

Reward (requires your class charm)
Bring the appropriate Class Charm you found in Kurast 3000 BA. Defeat the Dark Star Dragon on Destruction difficulty within 3 minutes after entering the level and without dying.

Duncraig
DIFFICULTY: EXTREMELY HARD


Level
Hatred : 95
Terror : 115
Destruction : 120

Location
Cave Level 2 (Act 1: Cold Plains)

Lore
The powerful demonlord Assur is on the move, burning a wake of destruction across the Western Kingdoms and turning the inhabitants of the towns he razes into mindless minions on his side. All efforts to stop him so far have failed thanks to Assur's powerful invulnerability rune. Find a way to kill him before he takes over the world.

Enemies
The possessed citizens and their Necromorb overseers are straightforward battles, but beware the ones that rush at you with lit powder kegs! They can throw the kegs over large distances and then light the fuse, which will burn down towards the keg and cause a devastating explosion that is almost always fatal to nearby adventurers.

Bosses
Assur wields powerful fire magic, but his main threat is the invulnerability shield. It is impossible to damage Assur directly. You will have to wrestle the secret to destroy Assur from his henchmen.

The secret
Retrieve the five demon seals from Assur's lieutenants: Skinrender, Spinecracker, Eyegouger, Fleshcutter and Bonehexer. On Destruction difficulty, each lieutenant drops his own seal. To reach some of them, you might have to use a teleporting skill. When you have the five Seals, kill Lost Souls and Necromorbs until a Ring of the Five drops. Cube it with all five seals to create Assur's Bane. Go back to Assur, then select your ring's Purify spell. This spell bypasses Assur's invulnerability and will take him out in a few hits.

Reward
Defeat Assur on Destruction difficulty to get Demonsbane.

Terror : 115
Destruction : 120

Location
Spider Cavern (Act 3: Spider Forest)

Lore
Valthek, a powerful mage of the Vizjerei Brotherhood has built a giant Empire, to reign for the rest of the days, and to serve him as a strong defense for anyone trying to steal the Ancient Repositories, which shall never be obtained by mortals. For this, he built his own Reign, the Yshari Sanctum. This gigantic maze is split in several stages with different powerful creatures. This subterranean dimension is guarded by the Prime Evils: You will need to face each one of them before you can destroy the Seal of the Gods, where Valthek is being protected, in order to keep the Ancient Repositories safe. Accessing them will reward any warrior greatly by enchanting his abilities.

Enemies
There are numerous powerful monsters throughout the maze that will test your battle prowess and running speed to the limit. You must be well versed in the various deadly arts and damage types to even think of venturing far into the maze.

Boss
Each stage will have a special boss, protected by several smaller bosses that also appear on the specific stage. You have to find them, they are located in special 'boss areas' hidden in the maze. Each boss might drop a set piece of the Brotherhood of the Vizjerei. Their fellow guardians will also have a bias to drop set parts of the Horadrim set. This means, you will need to obtain the 5 set pieces of each boss, and the 5 set pieces of their guardians, in order to be able to fight the last boss, Valthek. Each boss and minion has a chance to drop only their own set piece. While wearing the two sets simultaneously, you will be granted with new very powerful skills which are required to defeat Valthek, the Vizjerei Sorcerer.

DIFFICULTY: IMPOSSIBLE


Level
Hatred : 95

Location
Wretched Sands (Act 2: Duriel's Lair)

Enemies
On the first level, there are two types of monsters. Sand Maggot Eggs will spawn young Ghost Worms which are untargetable and will use a deadly poison attack, while the Eggs will prevent your heal. In other words, you just have to run like crazy and avoid dying, and get high poison resistances, because you cannot use potions.
The second level features no untargetable worms. You will be fighting Mothers, Eggs, Young Worms and Snakes. Once again, defense and poison resistances will be very handy here. You also need to have a decent kill-speed, because these worms will reproduce very fast.

Boss
Xazax will used ranged attacks and magic to try to kill you or drive you away.
