So, I have completed the "Ugly Baby" quest, and now I'm about to head in to. I don't have any quests that are lower level than this main quest, so I guess I should be okay to go here and then come back out to do the high level quests later? How many levels will I rougly gain in this area? Just so I know if I should complete a few quests couple of levels above me before going in or not."The Isle of Mists"
Do the Redania's Most Wanted, Deadly Plot etc quests, I believe you can fail the Deadly Plot arc if you start the Isle of Mist quest before finishing them.
