GW2 Halloween

GW2 Behind the Mask achievement guide

GW2 Behind the Mask achievement guide with detailed walkthrough. Behind the Mask is an explorer achievement released with the new Halloween patch. It is also a skritt burglar/treasure chest related achievement and therefore will have a number of possible locations within the zone. For this achievement, you will want to look for chests in Plains of Ashford, Diessa Plateau, Fireheart Rise and Fields of Ruin.


  • Press ctrl down while looking for these chests as it will highlight their names.
  • Best to do this with a friend so you can find the skritt burgler faster and reduce the waypoint costs
  • Do not use any pets/clones if possible as the skritt may transform your pet instead. This is especially a concern for rangers.
  • Focus on low damage attacks so you don’t kill the skritt burgler too quickly
