Id like to see it implemented in the following way: You set the target square for the spell, and the code indicates which other squares relative to the target are hit zones (x,y). This way you could cook up pretty much any aoe shape you wanted (like a customizable version of what disgaea uses for coding purposes anyway).
so something like (x+1,y+1) would allow it to also target the square diagnal from the target
possible friendly fire- but hey, sometimes sacrifices have to be made 
For the greater good, of course.
