A temporal incursion is a short-duration visit to the past wherein two Vaal architects are vying for control of a room within the Temple of Atzoatl. The objective is to murder one of the architects so that the other can prevail, thereby altering the Temple in the present time.
After completing No Time like the Present, Alva Valai will have a chance to spawn in most zones, allowing the player to enter three Incursions - There will be three seperate entrance points throughout any map she spawns in. She does not spawn in side areas or if the zone is more than 10 levels lower than the level of the player. Alva can also appear in maps. You can guarantee Alva to spawn by using an Atlas Mission.
During the Incursion League, she would appear in almost every zone, but would only allow access to one Incursion per zone as opposed to the current three.
Players have a short time, initially 10 seconds, to spend in each temporal incursion. During this time, they can (in descending order of priority):
- Kill one of two Vaal Architects who guide the temple's construction. This will either change the room in the present-day Temple of Atzoatl to a different type with different features, or upgrade it to the second or third tier of the same room for better loot. Damaging the Architect does not extend the incursion duration.
- Pick up a Stone of PassageStone of PassageThis item can be placed into an Altar of Passage to create a connection between two adjacent rooms in the Temple of Atzoatl. This item will drop on the ground when leaving an Incursion. that drops as loot and use it to open one of the locked (red) doors. This will open the corresponding passage in the present-day Temple of Atzoatl, allowing the player to access more of the dungeon.
- Kill monsters to extend the incursion duration and gain loot. The loot will drop all at once after the end of the incursion.
Notes: You cannot get the same incursion room more than once in one zone. To maximize the chances of fully upgrading a specific room, you will have to run multiple incursions over extra encounters.
Temple of Atzoatl
After 12 incursions, the completed Temple of Atzoatl dungeon can be entered and looted. Which rooms are accessible and what they contain depends on the player's actions during the incursions.
