Why..

Actually, if you can cast overlapping HDs on either side of the target and he takes damage from both that would imitate two meteors hitting.

And, 7seven7, about your point about my hypothetical situation being uncommon it very much is not. MS is a 7x7 area skill that can drop meteors centered on any area in that 7x7 area. Each meteor hurts things within a 7x7 area of where it falls (giving the spell a potential coverage of 13x13). Thus, if you're in the middle of the spell's AoE you will receive damage from most of the meteors since even the corners should be hitting you when they are hit by a meteor. So no, it doesn't take an insane amount of Wizards to stack up massive damage.

Finally, I don't believe that the final post is necessary Ayu. That's just the game checking for a valid path from target point to target. If you'll notice, when you cast in oddly shaped areas you seem to get less meteors (if you cast around a corner, for example). Only the meteors which would have line of sight (I believe to the casting point, but possibly to the caster) will actually fall. Therefore, if you cast MS around a corner, only meteors which fall in a way that they could target the cast point with a skill (as if they were players) will actually be created. The fact that it does not posses the no iteration flag should mean they will stack with other occurrences.
