Re: A Few Questions About the Evoker Wizard (Nuclear Wizard)
You could definitely make it bigger and would cover more overall squares if you did. So let's say we use the full 20' diameter. You would exclude 9 squares in the middle and then it would go 3 squares out form there. So it would cover a total of 72 squares, 9x9 for 81 less the 9 excluded.
The small radius just excludes the fewest number of squares in the middle, but especially if it's around you and you're not in melee yet, a larger circle could be useful. Just be careful because that could give the enemy a safe square to stand in and attack you. With only one safe square, you occupy it and anyone trying to attack you has to stand in the wall.
I just looked up AOE placement on different forums and some people require it to start at a grid line intersection and exclude squares in the corners, which would change my math, but the overall idea is the same.
I think the thing to keep in mind for wall of fire is if you make the circle up to a 20' diameter and then point it out, it covers a pretty good area.
