So I ignore the rules on humans being blind at night, it's simply wrong. Darn city-slickers.
Is that even a rule, though?
Under Vision and Light
Darkness creates a heavily obscured area. Characters face darkness outdoors at night (even most moonlit nights), within the confines of an unlit dungeon or a subterranean vault, or in an area of magical darkness.
Well then.
Next time someone here accuses me of thinking 5e is perfect, I can bring up this. This is silly.
. . . unless I interpret it as meaning there will be places in darkness outside at night (in the shadow of a wall, beneath a forest canopy) but not all the outdoors is in darkness. Yeah, that works for me. Okay. 5e is perfect again!
I am always amused at how far folks go to pretend work "within" a rule as opposed to just owning up and changing it when it fails."A creature in a heavily obscured area effectively suffers from the blinded condition (see appendix A) when trying to see something in that area."
I think the word effectively leaves some room for the interpretation that while the darkness of most nights imposes the mechanical effects of the blinded condition on humans, they are not in fact blind. For example, I would assume peripheral vision to facilitate movement outdoors on most nights.
