Corpse Explosion Shot

I've found this certain shot to be VERY powerful for only 666 gold. It deals damage in an AoE. Requiring a corpse doesn't mean much due to the nature of the creep pathing, either, because they're usually cluttered. Once your teammates kill a single mob, you can take the rest down in basically a single shot. Seems slightly unfair, and thought I'd bring it to your attention. I don't mind it being that strong, of course, but perhaps it should cost 6666 gold instead of 666.

I made it as powerful as it is because:
Positives:
- Huge damage
- Huge AoE
Negatives ( assume the "requires a corpse" restriction ):
- Many creatures don't leave behind corpses ( i.e. Skeletons, Flyers )
- Some enemies use corpses ( i.e. Necromancers )
- Your attack ability can target units, causing a constant interface obstacle with aiming to avoid attacking at a unit instead of the desired corpse.
- Other AoEs deal 50% more damage to the target it actually collides with. ( So Fireball deals 1.8*Power to the unit it hits and 1.2*Power to others in AoE. ) Since this missile never actually collides with a valid target, you don't get that bonus.

In the end, if I was to "nerf" the gun, I would increase the firing mana cost, not its price, because the Shot is just far too circumstantial to make it worth buying for more in a game that only saves one Shot.
