Skills

You are taking more damage from the Omnitect's thruster the longer you stand underneath it.

Lightning Exposure

Debuff

You have less Movement Speed and take increase Lighting Damage

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 deals constant damage, ramping up the longer you stand in 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, thin rows of lightning in all directions. They deal heavy lightning damage on contact and must be maneuvered around. The wave also apply a special version of Lightning Exposure.

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.

Version history

Version	Changes
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.
