Resetting Quests
Every Character on an Account has a one time Reset Quest State option. You can select this option at any time. Once you have used the Reset Quest State option for that specific Character, this option will no longer be available to that Character.
What does a Quest Reset do?
If you chose the Reset Quest State option for one of your characters, every single QUEST ITEM (these are the yellow colored items on your Characters inventory) will be removed from the Character. And then every quest journal entry, tasks and any blue quest markers will all be removed. Also it states "This will also reset your virtues to a near neutral state with some residual karma from past deeds". This WILL also reset all the known locations you have visited. So all the areas you have previously visited will have to be visited again.
You will then start the game on the Overland Map, and have only one quest in your Journal and Task List: Speak to Arabella. You character will now have no yellow quest items in their inventory. And if you use a Scroll to Zone scroll, you will not have any places yet to pick from (you will need to visit them). You can now proceed to do all the various Side Quests and the Chapter 1 Main Quest when ever you wish.
Using the Reset Quest State does not delete any other items in your inventory. It will only delete the yellow quest items in your characters inventory.
