An attack is very clearly defined by the PHB on page 270, and walls are attacks(by that definition).
Hmm. That's an interesting point.
Reading the description of "Attack" on p269, it says "When you attack, you make an attack roll", and it also says "All attacks follow the same basic process... 3. Make an attack roll."
Under Area Attack on p271, it says "When you make an area attack, you make a separate attack roll against each target in the area of effect."
All of this makes it sound as though an attack requires an attack roll, and if there's no attack roll, there's no attack.
However... one of the examples on p271 states "A magical wall of fog that springs from the ground to obscure a dungeon corridor is another example [of an area attack]".
Wall of Fog (Wizard Utility 6) has the Area keyword, and has the Effect keyword but not the Attack, Hit, or Miss keywords.
So does this mean that:
a/ the example is incorrect, and a magical wall of fog that springs from the ground to obscure a dungeon corridor is not, in fact, an example of an area attack?
or
b/ the example is correct; the Area keyword is sufficient to define a power as an area attack, despite it being a utility power that requires no attack roll, and all the references to attacks requiring attack rolls are general principles that don't necessarily apply to certain specific attacks?
