PoE Vaal Omnitect Drops Guide - Defeat The Vaal Omnitect in Temple of Atzoatl

The Vaal Omnitect is the final boss of the Temple of Atzoatl in Path of Exile. It's a challenging encounter that tests your damage output, dodging skills, and understanding of the boss' mechanics. Here's a breakdown of what to expect:

Location:

• The Vaal Omnitect resides in the Apex of Atzoatl, the final room of the Temple of Atzoatl.

Appearance:

• The Vaal Omnitect is a colossal construct with four monstrous heads, each representing a different element (fire, ice, lightning, and chaos).

Combat Phases:

The Vaal Omnitect fight has three distinct phases:

• Phase 1: Standard Combat:

  • The Omnitect attacks with all four heads, using a variety of elemental abilities and powerful slams.
  • It's crucial to dodge its attacks while dealing consistent damage.

• Phase 2: Energized Phantasm Phase:

  • The Omnitect activates a shield, becoming invulnerable.
  • It fires projectiles that spawn into aggressive Lightning Phantoms.
  • These Phantoms chase the player and explode on contact, dealing high lightning damage.
  • Your goal is to avoid the Phantoms while destroying the projectiles before they spawn them.

• Phase 3: Standard Combat (Return):

  • The Omnitect becomes vulnerable again and resumes its attacks from Phase 1.
  • Continue dodging and dealing damage until you defeat it.

Tips for Success:

• Movement Skills: Having a reliable movement skill like Flicker Strike or Leap Slam is crucial to dodge the Omnitect's attacks and Phantoms in Phase 2.

• Elemental Resistances: Ensure you have high elemental resistances (fire, cold, and lightning) to mitigate damage from the Omnitect's attacks.

• Damage Output: The fight can be lengthy, so sufficient damage output is essential to defeat the Omnitect before running out of resources.

• Phase 2 Strategy: Prioritize destroying the projectiles in Phase 2 to minimize the number of Phantoms you need to dodge.

Rewards:

Defeating the Vaal Omnitect offers valuable rewards, including:

• High-Tier Loot: It has a chance to drop powerful unique items, currency, and maps.
• The Vessel: This is a special map fragment required to access the Uber Elder endgame encounter.

The Vaal Omnitect

The Vaal Omnitect is the final boss of The Temple of Atzoatl.

• Apex of Atzoatl is the boss room of The Temple of Atzoatl, which always contains The Vaal Omnitect.

Location(s)	Apex of Atzoatl of The Temple of Atzoatl
Resistance(s)	Resists Elemental Damage Resists Chaos Damage
Modifier(s)	Unwavering Cannot be fully Slowed

To challenge The Vaal Omnitect players need to complete 12 temporal incursions, which Alva, Master Explorer will offer in areas or maps. The topmost room needs either to be connected to the room on the bottom of the pyramid or players must make use of Flashpowder Keg from an Explosives Room.

The Vaal Omnitect has several different skills. Each of its four heads attack autonomously.

• Laser blast - Marks several spots on the ground with a red laser, which all detonate afterwards.
• Lightning beam - Channels multiple lasers that deal lightning damage in small areas.
• Explosive flare - Fires balls of fire that explode and split into smaller fire projectiles in a nova.
• Summon Phantasms - Fires a ball that spawn into Phantasms, which chase the player and detonate for lightning damage on contact.
• Thrusters - Standing too close to the Omnitect applies a stacking debuff that deals Physical Damage over Time, ramping up the longer you stand near it.

At ~75% and 25% health, it will charge up and use one of two attacks while also gaining damage reduction for the attack.

• Flamethrowers - Spews four perpendicular rows of fire. Touching it deals large amounts of fire damage periodically. The Omnitect will move around and rotate occasionally.
• Lightning Wave - Launches multiple slow blue Wave of Convictions. They deal heavy lightning damage on contact apply a stacking debuff known as Omnitect's Paralysis, which increases Lightning Damage taken and reduces movement speed.

At 50%, the Omintect goes invincible, drops down at the center of the stage and spawns Energised Phantasms at the corners of the arena that move towards the Omnitect, restoring its Energy Shield if they touch it. These can be killed and provides flask charges.

The Vaal Omnitect can be augmented by upgrading specific incursion rooms :

• Lightning Workshop / Omnitect Reactor Plant / Conduit of Lightning : Augments the Omnitect with lightning. Lightning Defenses in walls are activated, sending lightning balls across the stage periodically.
• Flame Workshop / Omnitect Forge / Crucible of Flame : Augments the Omnitect with fire. Flame Turrets in the corners are activated, spewing fire periodically.
• Hatchery / Automaton Lab / Hybridisation Chamber : Augments the Omnitect with minions. Adds two Omnitect's Guards to the fight during the Energised Phantasm stage.
• Workshop / Engineering Department / Factory: Increases the life of the Omnitect. Gives 15/25/35% increased Life to the Omnitect.

Defeat Omnitect in Temple of Atzoatl Strategy

1. First complete 12 incursions by talking to Alva within the acts or in maps. Then talk to her to view the temple layout.
2. Click the Open Temple button to spawn 6 portals to the temple around your Map Device. Enter any portal.
3. Run north to the entrance, and navigate north-west (up-left) to reach the boss room. The image depicts an open door that can be passed through.These are doors that you unlocked using the Stone of Passage during previous incursions.
4. At some point you may come across a container that holds a Flashpowder Keg.This keg is very valuable and must be saved to open a blocked passage to the boss room (if it is blocked). Do not use it on mundate blocked doors as you may get only 1 in an entire temple, if any.
5. At some point you may come across blocked doors. These are passages that you did not manage to open using the Stone of Passage.Just backtrack, and find another way to reach the room.
6. As you can see in this map, the only passage leading to the boss arena is blocked and thus we have to blast our way through.
7. You can now use the Flashpowder Keg to blast our way through and enter the boss arena.
8. Before entering the boss room, spawn a portal so you can return to this point if you die. Then enter the boss arena door.
9. Defeat the boss, The Vaal Omnitect.
10. If you die, you can return to the temple using any of the remaining portals. If you kill the boss, portals will spawn to let you return to your hideout.

Version history

Version	Changes
3.17.3b	Updated the name of the "Lightning Exposure" debuff in the Vaal Omnitect Boss fight to "Omnitect's Paralysis", as it does not reduce Lightning Resistances.
3.14.0	Previously, the temple's boss, the Omnitect, dropped random rare items with special Incursion modifiers on them. Now, it also drops rare items with Incursion modifiers based around the themes of the rooms your temple contains, and has a higher chance to drop Vials related to that room. Having higher tier rooms also causes more rare items to drop.
3.3.0	Introduced to the game.
