Q409: The Warlock invocation GHOSTLY GAZE allows you to see through solid objects - does this allow you to see through fog and other heavily obscured areas? I assume yes as you can see through stuff.

How about magical darkness like Hunger of Hadar, Shadow of Moil, and Darkness? These spells don't specify what it is that blocks sight, just that they 'do.' Is this a case of 'don't think about it, just read the spell and it does what it does - no how is needed, logic will only make it confusing. Sure, you can see through solid stone or lead or rocks or creatures, but magical darkness isn't solid - it just can't be seen through without devil's sight."
