I need to get the Fragments from the raid. and the Hidden chests would help. Do you guys know where all of them? This is so I can pursue the Touch of Malice quest without having to worry about getting into raids.

I believe we looked up the location of the Calcified Fragments in our last run. I think there are 5, I only remember the location of 3.

Edit:
Hit this link and search for "raid" to find the 5 in the raid.

I imagine we'll be hitting all 3 chests.
