Hello again! My intent with it is that you do not need line of sight, as you are erupting flames all around you and wouldn't need direct line of sight to have that sort of effect.
Nice, thanks! I also think that makes more sense. If not, sometimes you can get in a weird situation in which you don't have line of sight on the same row/column, but you have if you move to a diagonal, that obviously is of no use for that attack.
