Primal Nature?

[Iscah]

The requirements for Primal Nature are completing the Titan Hard Mode unlock quest, which necessitates the completion of The Navel (Hard) itself. However, since you used a story skip, both the quest and the instance should be checked as complete for you, as completing Titan Hard is mandatory to begin the patch 2.5 story quests, and you need to enter the instance again as part of patch 3.4 story quests..

The quest will be completed as part of the story skip, and the trial should be available, but it isn't marked complete until you have personally done it.
