Something Dastardly Stirs in the Seasonal Questline

[Link]

Following disturbing events in Ked Bardu, meet with the assassin Shyan to root out the source of terrible new demons. Shyan belongs to the order of the Viz-Jaq'taar, responsible for eliminating demon-corrupted mages. The Viz-Jaq'taar were created by the Vizjerai after the Mage Clan Wars, a brutal conflict in Sanctuary's past. This order is now set on seeking the source of these new Chaos Rifts that spread destruction across Sanctuary. The signs point to a plot from the Fell Council, and the unmistakable return of Bartuc, Lord of Chaos, signaling Mephisto's influence among these events.

[Link]

To begin the Seasonal Questline Sands of Chaos, head to Ked Bardu in the Seasonal Realm and speak to the distraught villager to join the hunt.

Infernal Hordes Reborn

[Link]

Bartuc's return to Sanctuary has stoked the flames of the Infernal Hordes and the fires of the Burning Hells are hotter than they've even been before. The Infernal Hordes is shaking up in several key ways: Chaos Waves, the Fell Council, Bartuc, and more.

Chaos Waves

[Link]

Among the Infernal Offerings within the Infernal Hordes, Chaos Waves enter to throw your visit to hell into a bloody frenzy. Chaos Offerings will occasionally appear between waves, transforming a standard wave into a volatile crucible of randomized, rule-breaking encounters. These high-intensity combat trials aren't for the faint of spirit, with each type imbuing havoc and intense challenge. These waves will have significantly increased difficulty, but reward far more Aether should you be able to survive.

[Link]

Chaos Waves will have many different combinations to discover and master. Dodge deadly projectiles from Chaos Rifts, slay a rampaging Hellwyrm, or hunt down erratic Aether Goblins. Chaos awaits!

[Link]

Confront Bartuc, Lord of Chaos

[Link]

At the end of your Infernal Hordes run, you'll be met with a choice. Choose to fight against the tested Fell Council, or up the ante and throw down against the insidious Bartuc. Read on for more details on the Lord of Chaos' return.

Dialing up the Heat in the Infernal Hordes

We've changed the moment-to-moment combat within the Infernal Hordes in a few different ways. First, we've done an overall re-work of the Infernal Offerings revealed between each Wave. Our goal is to try and make all offerings feel valid as choices for you as you start to stack them to focus on your run. This includes additional balancing to ensure that Infernal Offerings are more balanced across the board compared to the Hellborne wave, which has been seen as essential for the best possible Infernal Hordes run.

Hell has unearthed a new monster family-Chaos Monsters-from deep within its horrid maw. Born of smoke and brimstone, some of these Chaos Monsters provide a mighty shrine-like buff when killed. Slay Chaos Bringers to earn a temporary buff, which can be increased in duration through the Urn of Sustain from Seasonal Blessings. For the advanced demon slayers, if you can manage to kill another Chaos Bringer before your first buff expires, they'll stack.

[Link]

Additionally, the door to enter the Infernal Hordes now opens much more quickly than before. Usually, people are slightly more reserved to enter the Burning Hells, but not you, wanderer.

The Fell Council

The Fell Council has had some promotions. When fighting them, one of their members will now be the designated Council Speaker and gain enhanced abilities.

Slake your Bloodthirst in The Fleeting Hordes

We're introducing a warming version of the Infernal Hordes to burn through earlier in your character journey. You can play this trimmed down version of the Infernal Hordes in pre-Tournament Tiers.

Fleeting Hordes will be four waves in total, with limited Infernal Offerings to keep the packs of vicious monsters under relative control. Upon completing the final wave, you'll fight two of the Fell Council members before you can spend your hard-earned Aether for rewards.

Bartuc Beckons

[Link]

An infamous Vizjerei Warlord known for his acts of cruelty performed in the Mage Clan Wars, Bartuc's perversion knows no bounds. He returns to Sanctuary with a new title, the Lord of Chaos.

To fight Bartuc, each member of your party will need to spend Aether for the chance to eliminate this cruel threat. The first member of your party who selects Bartuc decides for the rest of the party.

[Link]

Bartuc will harness Chaos portals to shoot projectiles at your location and deploys an arsenal of malevolence to claim your life. Master his tactics and use the teleport pads strategically to gain the upper hand.

Similar to other bosses starting with Season of Infernal Chaos, Bartuc's invulnerability phase can only occur after 10 seconds of the fight has elapsed.

Upon defeat, Bartuc's rewards will appear on the ground, so you do not have to spend additional Aether to earn these rewards.

Back to Top

Harness Entropy with Chaos Armor

[Link]

The only certainty is that nothing is certain. No entity is free from Chaos's grasp-human, Horadrim, Angel, or Demon. All dance in its path, so rather than succumb to its erratic forces, harness this untapped power for yourself.

A new Unique Armor type has entered Sanctuary. Chaos Armor is a more fearsome version of existing Unique items that come with a diabolical twist. Chaos Armor are existing Unique items which appear as more formidable counterparts fit for other item slots, leading to entirely new ways of dispensing carnage.

[Link]

Chaos Armor can appear in the following item slots:

  • Helm
  • Chest
  • Gloves
  • Pants
  • Boots

Chaos Armor will only appear as an item fit for anything other than its original slot, and the color of their item names are distinct. For example, Flickerstep won't have a Chaos Armor version in the Boots slot. The aspects on Chaos Armor are also more potent than their normal counterpart, always appear at Maximum power, and have at least one Greater Affix.

[Link]

Note: you won't be able to equip the same Unique item between Chaos Armor and standard Unique.

For example, you could have Fists of Fate drop as a Helm instead of Gloves, allowing you to equip a different set of Unique Gloves to compound those affixes in a combination that was previously unavailable. Theorycrafting is the name of the game this season.

[Link]

To earn Chaos Armor, defeat Bartuc in Torment III and IV for a guaranteed drop. Defeating Bartuc in Torment I and II also has a smaller chance to drop Chaos Armor as well.

The following Uniques will be available as Chaos Uniques:

Seal Chaos Rifts

[Link]

Strange portals of crackling energy have appeared across Sanctuary, unleashing the Burning Hells' legions through their wicked rifts. Chaos Rifts materialize to terrorize the denizens with untold fury.

Chaos Rifts appear within Helltide and Nightmare Dungeons. Put down the demons pouring from them and seal them away for seasonal reputation and Infernal Warp, which is used to level up your Chaos Perks. They're also a great source of chaotic loot, granting additional experience, gems, and Chaos Armor in Torment difficulties.

In extremely rare cases, when playing in Torment difficulties, you may even come across a Chaos Rift of Mythical proportions...

[Link]

Chaos Rift Nightmare Dungeons

Chaos has seeped into the fabric of Sanctuary's Dungeons, delivering bloodthirsty Chaos Monsters through these grim halls of carnage. These Nightmare Dungeons are rife with Chaos Rifts, which are great sources of fleeting Hordes Compasses. Since the PTR, these Chaos Rifts now provide similar rewards to their overworld Helltide counterparts. Additionally, the stacking getting hit by an attack from a Chaos Portal no longer increases your overall damage taken.

Back to Top

Wield Devastating Chaos Perks

Invulnerability phases can now effectively bypassed if the player exceeds certain damage thresholds.

At 2/3 and 1/3 Life the boss gets a shield, which lasts for five seconds. At 2/3 of remaining Life, the shield's value is 1/3 the boss' max life. When the boss is at 1/3 Life, the shield's value is 2/3 the boss' max Life. If they player breaks the shield with those five seconds it's active, the boss does not become invulnerable.

One such rarefied find from the far reaches of Sanctuary is the Rogue Shadow Viper Armor set, which contains the Shadow Viper Armor set, Sinuous Suffusion marking, Sunken Fan Dagger skin, and Sidewinder Crossbow skin. This can be purchased from Tejal's Shop for 2,800 Platinum.
