- Your characters will retain their current levels, items, and abilities.
- If a character has completed one of the beta quests, he or she will receive credit for completing its revised, final version. (A couple will get new names as part of the switchover.)
- Honors will also translate over.
- Any incomplete quests will be removed, and your party's timeline of events will be cleared. We'll announce the switchover in advance so that you have a chance to finish them off beforehand.
You can of course choose to start fresh with a new character, and there are some advantages to doing that. The current quests will be revised significantly in many cases: their stories will be expanded, and they'll offer new combats, choices, and items to discover. Some of those choices will come with benefits later in the story, too. If you want to experience all the options that are available in the final campaign, starting fresh is the way to go.
Hope that makes sense. If you've got any questions, let us know!
