Some have theorized that drow-Tavs don't suffer Sunlight Sensitivity because of the OP tadpoles (like Astarion having less...life threatening weaknessess...as in none). I like that idea but it would be nice to have it explicitly mentioned in game. This could also give a bit more incentive for drows to agree with Astarion (who wants to control the tadpole).
I think if you appear to be a drow, the goblin that speaks to you when you enter the blighted village the first time comments on your being a drow in sunlight, and assumes you’re a true soul because of that. So there’s some implication there that the lack of sensitivity is tadpole-related.
I’m still not convinced though. I had thought drow sunlight sensitivity was a natural adaptation to living in low light in the Underdark, whereas a vampire’s inability to go out in sunlight was more supernatural in origin. Of course, it’s not really possible to say what does and doesn’t make sense for a fantasy tadpole, but somehow the idea of it changing supernatural attributes seems more reasonable to me than changing natural ones.
That aside, if I were suggesting a way to do it, I think I'd start with the idea of saying that it gets dark after two short rests and then gets light again after a long rest.
It sounds as good a way of moving time along as any. But there’s still the question of what happens at night. Unless there are important differences to the world during darkness hours, I personally would not be hugely keen.
Plus, unless you effectively wanted to “waste” your second short rest, you’d be forced to spend some time exploring the world during darkness every day, when sensible, non-drow adventurers would be more likely to want to camp for the night.
