Expedition: Undercroft is a Lost Zone expedition in Aurelian.

You've pressed deeper into the monastery, and it's surprisingly well preserved. Stranger still are the remnants wandering the halls—echoes of the people who once lived here. These remnants may hold the key to moving deeper into the ruins... but they may be dangerous.

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.

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.

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.

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.

Arclight Overload

Main article: Arclight Overload

Occasionally in the ruins, an Arclight Sage can be found stabilizing an orb of arclight. Upon approach, they will call to Wayfinders for Arcstone.

Clinical Trial

Main article: Clinical Trial

The event is located in Solarium's Vale, an open-air hall with staircases leading out. In the center of the room is a Memory Fragment, which will start the event when touched.

Decoder

Main article: Decoder

The event is located in the Radiant Scriptorum, a courtyard with stained glass and three decoder devices. In the center of the room is a burning light, which activates the event. The Decoder event has two variants:

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.

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.
