Siege of the Atlas Guide / Hub (PoE Archnemesis 3.17)



In Path of Exile: Siege of the Atlas, two new Eldritch Horrors threaten to consume the Atlas of Worlds. We are joining Commander Kirac’s militia and defending the Atlas and Wraeclast itself against these celestial foes. This large endgame expansion contains new Atlas systems, pinnacle bosses, one gigantic Atlas passive skill tree, Eldritch implicit endgame crafting, new unique items, the Archnemesis Challenge league.

Two New Bosses!

The Searing Exarch and The Eater of Worlds are the most powerful beings that Wraeclast has ever seen. The path to defeating them involves exploring many influenced maps and slaying their formidable subordinates, The Black Star and The Infinite Hunger, yielding valuable rewards.

Reworked Atlas Mechanics

Most Atlas mechanics have been reworked with the goal of creating deeper systems that are easier to understand. Regions have been removed, so your Atlas specialisation affects every map you run. Where you’d previously collect 16 Watchstones, you must now earn four Voidstones which let you raise the tier of all maps on your Atlas until they are uniformly tier 16. Sextants can apply to Voidstones and be itemised and traded. Commander Kirac offers a large variety of Atlas objectives that add valuable content to your maps.

The New Atlas Passive Tree

Say goodbye to regional Atlas Passive Trees and hello to one gigantic Atlas-wide Passive Tree with over 600 skills to specialise in. Every map as well as various Atlas quests you complete will earn you an Atlas skill point. In addition to the best skills from the regional trees, we have created many completely new ones that let you choose your own level of risk and reward for Atlas content.

Eldritch Implicit Modifiers

The Searing Exarch and The Eater of Worlds each have a powerful set of Eldritch Implicit Modifiers, which can be imbued onto items using Eldritch Embers and Eldritch Ichor, respectively. Although this process replaces existing implicit mods, it’s possible to have both types of Eldritch Implicits on an item at the same time.

You can use an Orb of Conflict to manipulate the tiers of these modifiers on your item, within the six tiers of modifiers available. When applied, the Orb randomly increases the tier of one modifier and lowers the tier of the other. The new Eldritch Chaos Orb, Eldritch Exalted Orb and Eldritch Orb of Annulment can manipulate the prefixes or suffixes of an item depending on whether The Searing Exarch or The Eater of Worlds has a higher Eldritch modifier on it.

Powerful New Unique Items

The four new pinnacle Atlas bosses each have their own drop pools of new unique items to find. There are more than a dozen in total and they represent some of the most powerful unique items we have introduced to Path of Exile yet, enabling exciting new character build opportunities.

The Archnemesis Challenge League

In the Archnemesis league, you’ll build your own Rare boss fights by applying new monster modifiers to petrified monsters, found throughout every area. These modifiers add dangerous behaviours to their targets but also imbue them with valuable rewards. Each subsequent petrified monster you imbue within an area keeps all of the previous modifiers applied, allowing you to build some extremely difficult and rewarding encounters. There are over 60 new boss modifiers to discover, more than half of which can be created by combining other modifiers in specific recipes to unlock the most powerful and rewarding modifiers.


Building Your Archnemesis

Recommended Builds for Siege of the Atlas and the Archnemesis league

  • GhazzyTV’s Skeleton Mages Necromancer is going to be the best minion build of the Archnemesis league; this build excels in not only getting your maps clear but it’s an excellent boss killer. With the new Atlas bosses, this build will not let you down and is described as the most OP minion build of the league.
  • GhazzyTV’s Chaos Dot Occultist is a classic build that has stood the test of time for many leagues. Giving good clear speed and consistent bossing damage, the build is perfect for both beginners and veterans alike and a solid league starter choice.
  • GhazzyTV’s Blade Blast Bladefall Poison Assassin is one of the most prominent choices for both SSF, hardcore, as well as trade leagues. This build brings very enjoyable clear speed as well as efficient bossing to the table. It has very interesting mechanics where you cast one skill on top of another skill creating massive explosions and poisoning the enemy.
  • TbXie’s Herald of Agony Juggernaut is back on the table as one of the best tanky builds around in any scenario of the game. The build has an insane damage reduction of reaching 89% elemental damage reduction and 92% Physical reduction. While this obviously makes it very tanky, it still maintains 3-5M Shaper DPS.
  • TbXie’s Arc Elementalist has seen some gigantic buffs in the Archnemesis league. Arc is going to be a very strong self-cast build. This build is amazing for Solo Self-Found where you can reach 2M boss damage and 10.000 effective health. A very strong contender in the new league.
  • TbXie’s Freezing Pulse Totems Hierophant has been one of the most popular builds for newer players for the longest of times. Especially after recent tree changes, it pushed its single target boss killing capabilities up by quite a significant amount. This build is an excellent one for both new and experienced players alike.
  • Furty’s Lacerate Gladiator has been a staple of league starts and Solo Self-Found alike. With the addition of last league Masteries and an improved tree, this build is more flexible than ever and has one of the smoothest transitions from Merveil to end game.
  • Furty’s Bladestorm Berserker isn’t one of the most known builds, but it has the potential to be one of the most powerful builds. It has extremely high damage is backed by stable leech, life, and mobility, allowing you to carve your way through the endgame with confidence. An added bonus is that Bladestorm is a great skill for leveling, making it a great choice for any melee league start.
  • Furty’s Essence Drain/Contagion and Blight Trickster – name a more iconic duo. This chaos damage combo has been tearing apart maps for years and is still virtually unmatched when it comes to raw clear speed in maps. One of the best builds for solo self-found and a solid choice for to unlock the new atlas.
