Temple of Tutankhamun (Duat)
The central location of the Duat Afterlife. You'll be brought here automatically at the end of the main questline, but you won't have much time for looting then.
One treasure is outside, in a jackalman camp northeast of the front entrance.
Drop down from the temple for a dropkill/chainkill combo of anyone in the area, then loot the red chest at the statue base.
The other treasure is inside the main hall, on the platform to the left (north) of the throne.
Snag it to complete the location.
