Apex of Atzoatl is the boss room of The Temple of Atzoatl, which always contains The Vaal Omnitect.
The Vaal Omnitect is the final boss of The Temple of Atzoatl, introduced in the Incursion leagues.
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.
Untiered (or T0) incursion rooms are rooms with no resident Architect.
A T0 room will contain two random Architects who are not currently a resident in the current Temple layout.
During the present-day Temple run, untiered incursion rooms are not occupied by an Architect, and have no additional modifiers or effects on the rest of the Temple.
