There are fifteen different Daedric Artifacts that are available via quests from each Daedric Lord’s shrine. The Main Quest will direct you towards Azura’s Star, but this is actually one of the most useful Daedric Artifacts for almost any character because it serves as a reusable Soul Gem. I personally used the Wabbajack from Sheogorath, but any Daedric Artifact will suffice. I’ve assembled a list of all fifteen shrines, artifacts, and a few details on how to activate the quests Here
. The list is organized according to the level of character required to begin the quest and any of the fifteen will serve to unlock the achievement once you deliver it to Martin at the Cloud Ruler Temple.
