Events

Possible events that may spawn in this expedition.

Altar of the Phoenix

Main article: Altar of the Phoenix

The Altar of the Phoenix is an Event found in all Lost Zones. Interacting with the altar will summon a phoenix that must be defeated to earn rewards. The type of phoenix and mechanics of the event differ depending on the zone. It is possible that applying the Phoenix Eggs mutator (Greed + Solar) makes it more likely for the altar to appear in the Lost Zone.
The Loot Phoenix must be defeated multiple times within two minutes. Each defeat will ignite one of the summoning altar's rings while the phoenix will respawns. Up to eight of the rings can be ignited for maximum rewards. The event ends when the timer expires.

Deception

Main article: Deception

The Deception is group of four chests. The goal of the event is to pick the two chests without deceivers hiding inside. Hints to those chests are:

• In the distance deceivers can be seen hiding in their chests

• Close by the deceiver chests can move around

Failing means to confront both deceivers in combat.

Gloom Ambush

Main article: Gloom Ambush

A Gloom ambush will always occur at least once during a Lost Zone expedition and, in most cases, cannot be bypassed. The ambush takes place in certain rooms which will have a Memory Fragment in the center. Picking up or passing the fragment will seal the exits and initiate the event. Players outside of the ambush can pass through the one-way barriers into the room.
Various Gloom enemies will spawn in two waves, with the second wave starting after a majority of the first wave has been defeated. Tidings, Wretches, Foul Wretches, Husks, Heralds, Seers, and Oracles may spawn throughout. The high volume of enemies, as well as fighting in an enclosed space, may make certain Imbuement effects extremely hazardous.

The barriers blocking the exits will dissipate once all Gloom enemies have been slain, and the remaining enemies in the Lost Zone will have their levels increased by one.

Loot Goblin

Main article: Loot Goblin

The Loot Goblin is a special enemy unique to its own event in a Lost Zone. The Loot Goblin is a goblin toting a large overflowing treasure chest on its back, and it is always first encountered rummaging through an already opened treasure chest with a pile of treasure in front of it. Defeat the goblin before it escapes, and its spoils are yours for the taking. As the Loot Goblin is an icon of greed and avarice, it is arguably more likely it will appear if applying a Greed Imbuement to the Lost Zone.
Upon a Wayfinder approaching or damaging the Loot Goblin, the event begins, and the Loot Goblin will begin to flee. Players must defeat the goblin within one and a half minutes, or else it will completely flee the zone and cause the players to fail the event. The Loot Goblin will run away in short bursts, stopping after a few steps to taunt the Wayfinder; it will never attack back, only retreat. Breaking the goblin's Resilience will cause it to drop immobile on its back for a duration. Upon the Loot Goblin's defeat, the event is immediately concluded, and rewards are provided, including a number of the goblin's signature reward, the Gem of Avarice.

Trickster Events

Main article: Trickster Events

Trickster events are found in all Lost Zones. There are 3 variants of these luck based mini games. A player can interact with Trickster's Game multiple times per encounter. All variants share, that the wayfinder has a limited amount of attempts to get the grand price, various loot and some of the Trickster's Coins. Group members can either get the same price by staying in close proximity while the game is played, or simply open the last chest for free at a later time.

Exterminator

Main article: Exterminator

Exterminator is an Aurelian Event that exclusively occurs in Codex Halls Expeditions. A pair of crystal webs within the ruins will spawn Broodlings until they have been destroyed.
Two random locations within the Codex Halls will have a nest made of crystal webbing, which will spawn unique crystalized Broodspawns and Broodhunters. These enemies will respawn from the webbing when defeated until the nest itself has been destroyed.

On rare occasions, both nests will spawn in the same location.

Gelatinous Cube

Main article: Gelatinous Cube

Gelatinous Cubes are interactive Events found exclusively in Aurelian Lost Zones. They can be broken to reveal the contents within:

• A Treasure Chest of random size
• Encoded Tracers or a random Data Fragment
• Ichor grows from the cube's remains:
  • Three Ichorlings
  • A single Ichor
  • Rarely, Vaelor's Blood may spawn

In addition, an Unyielding Cube may be rewarded when destroying the cube.

Orbital

Main article: Orbital

The event is located in The Great Orrery, which is a large room with a ruined staircase leading to smaller, sealed room. A small device in front of the sealed room can be activated to power the orrery above, beginning the event.
After activating the device, a light travels from the device into the central orb, revealing energy rails for the smaller orbs and designated locations for them. The smaller orbs must be aligned with the illuminated diamond marks to unlock the sealed room. On the top floor of the room are three to four panels, which each control one of the orbs. Stepping on the panels will move an orb along its orbit line, and stepping off will halt its movement. A musical note will indicate when an orb has been aligned.

Tracer

Main article: Tracer

Tracer devices can be found randomly through out the Aurelian ruins. Upon activation, the device will rise from the ground and begin its defense system.
The tracer will spawn enemies in waves, typically consisting of a few weak enemies like Goblin Scavengers, Broodspawns, and Ichorlings. In the Undercroft and Repository, Codex Initiates and Codex Monks may appear. Known enemies include:

• Goblin Scavengers
• Goblin Hunters
• Goblin Hackers
• Goblin Seers
• Broodspawns
• Broodhunters
• Ichorlings
• Ichors
• Codex Initiates
• Codex Monks

After defeating all waves, the device will open to reward the data within.
