This achievement can be a little complicated to figure out what you have to do, but it's not very difficult once you know what you're doing.

To get this achievement you have to "Complete the 5 Serqet locations". There are also locations in the game called "Scorpions lair's" which look the same as Serqet locations but DO NOT count towards the achievement, so don't get them mixed up.

There are 5 locations you must complete. 4 of them in the different afterlife's (1 in each Aaru, Aten, Heb Sed and the Duat), and 1 in the real world.

First, you must complete the 4 locations in the afterlife's. The 4 Afterlife locations require you to kill the king scorpion (the golden one marked with a crown around its level). It is recommended to be at least level 55 before trying. They are located at these locations:


Once you have completed all 4 locations, return to the real world. In the real world you must visit the location called "Spring of Serqet outpost" and complete the location the same as any other outpost. Once you have completed it you should unlock the achievement as well as a new outfit.


And there you have it. I hope this guide helped :)
