Some spells can push the target X feet away (like thunderwave, which pushes 10 feet away on a failed save). I was wondering what happens if the target, while being pushed, encounters a wall or other rigid object. Does it take (bludgeoning) damage? To me it seems logical that it would: it is like falling, sudden force applied to a creature due to encountering resistance from an object.
I couldn't find any rules about this in the Player's Handbook nor online.
