Hey Gamers! Welcome to March of Sacrifices, part of the Wolfhunter DLC in Elder Scrolls Online!
The below video will cover this dungeon on Veteran Difficulty (although this particular achievement only requires Normal mode, veteran is needed Wolfhunter Delver Achievement).
Please note the final boss is done on "hard mode," and you do not need to take part in hard mode for these achievements, and it will actually be slightly easier.
Nonetheless the purpose of the video is to cover all the boss mechanics of the dungeon, and we hope you find it helpful!!
