There are five locations in total: 4 in the Afterlife, 1 in each area (Aaru, Aten, Heb Sed, Duat), and 1 in the real world. The 4 Afterlife locations require you to kill a level 58 scorpion, so I recommend reaching level 55 before trying. The scorpion with the crown over its level is the one that needs to be killed to complete the location. In the real world, you must visit the Spring of Serqet outpost and complete the location. Upon completion of the 5 locations you will also receive a new outfit.
