Metamagic and Multi-target spells

[Tels]

How do metamagic with special effects and spells that target multiple people (even the same person multiple times) interact?

Specifically, I'm referring to a dazing magic missile, would a person targeted by all the missiles have to make multiple saves? Or a toppling magic missile, do I get to make multiple trip attempts on the same person?

I ask because I've currently got a level 13 admixture Wizard with 4 Archmage mythic tiers and magic missile is one of her mythic spells. If she were to augment it, then it would fire double the normal amount of missiles (10 total) and each one deals 2d4+1 points of damage and bypasses spell resitance, spell immunity and shield spells or effects.

If dazing, or toppling were to apply to each missile she fires, then she could force 10 will saves, or make 10 trip attempts with a single spell. This same line of thought applies to spells like scorching ray, or contagious flame as they are both capable of single, or multiple, targets.

Now, I'm inclined to believe that the affects of such metamagic feats would apply to each missile or attack of the spell, as a dazing fireball would daze anyone in the area of effect that fails their save. The difference is that fireball only has one save, while a dazing magic missile could force up to 5 saves (or 10 if using mythic).

On the other hand, this makes spells that can single target, like magic missile very good choices for the effects of feats like dazing or toppling spell. Especially if combined with heighten spell. Even worse if one has a dazing metamagic rod as they could force multiple high DC will saves or lose their turn for multiple rounds.

Hmm.

You can modify a spell to daze a creature damaged by the spell. When a creature takes damage from this spell, they become dazed for a number of rounds equal to the original level of the spell.

Strictly as-written, dazing spell is far too powerful. Lots of things you can't stun can be dazed (golems, for instance, apparently). And if you put it on something that has continuing damage, it's insane.

My GM has long-since declared that you get at most one chance to daze any specific target with any specific spell.

My intuitive ruling would be: If a creature takes damage from the spell, then they get to make a single save to avoid the daze. Either that's the spell's already-existing save, or it's a will save added by dazing spell. Then they have rolled their save and are or are not dazed, and dazing spell is done.

So my opinion: It applies to each missile, but doesn't stack. If you hit five targets, then five targets make saves. If you only hit one target, no matter how often you hit it, it makes a save.

Are there any other cases where a spell can hit the same target multiple times, and allows a save? Do any of them specify that you make multiple saves, one per hit? All I can think of is that prismatic spray can require two saves, and prismatic wall can require up to seven (more, depending on how the poison works?). Oh, hey. Meteor swarm!

Quote:

If a creature is within the area of more than one sphere, it must save separately against each. Despite stemming from separate spheres, all of the fire damage is added together after the saves have been made, and fire resistance is applied only once.

Ignoring for the moment the difficulty of casting a 12th-level spell: What do you think should happen with a dazing meteor swarm? I think, just because I am feeling nerf-happy, that the answer is that if you make any of the saves, the daze is negated. :)
