The Dew drops from the Desert Jinn are not guaranteed, they never were, so having a run of no drops would be normal. I would like them to be a guaranteed drop because of how much the Jinn cost, but getting a few more is a bonus to help towards the timed component. I think I'm going to give myself a bigger margin between parts 2 and 3. I'm now waiting for the dew to do part 2's desert offering. Kinda can't bring myself to start crafting for part 3 yet, but there's no hurry either.
