If you mean the other thing I think you mean, because a 20 ft radius circle, on a grid that considers diagonal movement as 1 square(or 5ft.), becomes a square, not a circle.
I believe Merric is suggesting that the two can be independent of each other. This is true, and even works in the odd world setup I posited in the much, much longer geometry thread.
Do we have anything beyond speculation that flare squares have replaced fireballs? How do DDM2's fireballs work?
