I was thinking we could try to get our Reliable favor reward with The Coin Lords & at least hit level 4 next Tuesday. Here's my thoughts for quests.
First, in any order: The Kobolds' New Ringleader, Garrison's Missing Pack & Kobold Assault. We should have reliable rank after these. Then move on to WaterWorks. If I calculated the XP correctly, we should hit XP for level 4 after part 2, then we can level up & move on to parts 3 & 4.
