Spellcasting after an Enemy Dies

[ShivenCasull]

If the enemy runs out of the range it is unaffected, but ANYTHING alive or dead will be affected in that range, much like how blizzara and flare already operate with yourself as the center point.

I would greatly prefer a system like the one above. it's easier to see what will be effected by the AOE ability, and since it would be targetable on an area there could even be different spell effects. Firaga / Blizzaga for instance could leave a fire DOT or a area of effect slow.
