Spawned from related: What does it mean "to see" when casting magic missile?
A circumstance occurs when I am no longer able to see my opponent. Fog Cloud was conjured over me, and I am blinded. I now lost sights of my opponent.
If I use Clairvoyance, and take the "seeing" sense, would I then be able to use a ranged attack or spell against my opponent? If examples are necessary, a ranged attack will imply an arrow being shot, and a spell would imply Magic Missile, for argument sake.
In the case of a physical object being in the way of you and your target, say a wall, I understand that you lose a clear path to your target, although it would generate a lot of "cool" points if your Magic Missile would bend around a wall and hit your target. I am uncertain, however, about the interaction between being blinded, Clairvoyance, and ranged attacks/spells.
I am looking for RAW, as opposed to any house rules, and primarily focused on targeted spells and attacks, and not area-of-effect such as Fireball.
We can safely assume that range limitations of all attacks, spells, and Clairvoyance are not being exceeded.
