Say an anti-magic field is pointed at me (say, by a beholder looking at me with its central eye).

Say also that I am out of range of the anti-magic field.

Can I cast an Ice Storm spell at a point behind the beholder (so as not to be in the field)?

Situation w/ arrows for facing:

ME->........................................ ............<-BEHOLDER <ICE STORM HERE>

Or is the "line of effect" blocked, and the spell doesn't work?

I would assume you would cast the ice storm above the beholder. In any case, I would rule that you can see past your opponent.

It's not seeing past the opponent that is the problem, its casting through the Anti-magic field. Does the AMF cone effect break Line of Effect? I believe that to be the true question.

There was a discussion of that in this thread (http://boards1.wizards.com/showthread.php?threadid=143257), and I believe the general consensus is that it does block LOE, though there were a few dissenting posts.

:b: I don't believe AMF will stop LOE in most cases.

From the SRD AMF
An antimagic field suppresses any spell or magical effect used within, brought into, or cast into the area, but does not dispel it.

LoE is sight only, if you can see the target area than you can cast it there. When casting Ice Strom your at point A and the spell appears at point B.
Ice Storm would appear where you want it and affect it's normal area minus the AMF. So if Party members are in it there safe, because the magic is suppressd as it enters the area.

Spells like Lighting bolt start at you and travle forward. The spell is in affect between you and the AMF and than stops. This includes cones and missiles.

One last exception to note are spell like Frie Ball that state that the magic enegry travles from you to the target area.

without over analyzing i would simply say no it wouldnt stop the spell. if the caster was in a small hallway and the area of the anti-magic cone filled up the are of the hallway but the caster was outside the spell i would say the spell wouldnt work then. i would situation rule it but most of the time the spell would work.

Wall of Force is invisible, but blocks LoE. You can see through a glass window, but it blocks LoE. You can't see through fog, but it doesn't block LoE. LoE and sight are independent.

From the SRD:
Line of Effect: A line of effect is a straight, unblocked path that indicates what a spell can affect. A line of effect is canceled by a solid barrier. It’s like line of sight for ranged weapons, except that it’s not blocked by fog, darkness, and other factors that limit normal sight.

The question is what counts as a "solid barrier" for a magic spell? It can easily be argued that an area where all magic is supressed would seem like a "solid barrier" to a spell trying to get past it. Then again, an AMF is definately not "solid" in the conventional sense of the word. Personally, I can see it just as easily either way. *shrug*

(This made me think of an interesting question. Does Solid Fog block LoE? Fog normally doesn't block LoE, but this is "solid" fog. Of course, you can still move through the fog [albeit more slowly], so it's not completely solid. The spell description does state that "magic rays and the like" are not prevented [unlike "effective ranged weapon attacks"]. Does that include LoE? Exactly how much "solidness" is required to block LoE?)

So, you're basically saying that it would block LoE, but spells can normally travel "around" it to their target. This goes against the whole LoE concept. I think it would probably make more sense to rule that it either blocks LoE or it doesn't.

Of course, I might just be over analyzing it. ;)

Look as long as you have an unbroken line of effect between you and where you want the spell to occur, then you are good. So unless you are like right at the very edge of where the anti-magic cone ends, then you should have an unbroken line of effect over top the beholder.

You don't cast ice storm straight at your opponent. You cast ice storm above your opponent and that requires an LoE which is a diagonal leading up.

If you tried to cast ice storm behind the beholder at the same height level as the beholder, then your ice storm would fail. However, if you used the spell correctly by casting it above the target, then you should have an unbroken LoE.

You actually chose one of the few spells that wouldn't have a problem with the Beholder Anti-magic cone. You could not for instance cast a fireball and have it go off behind the beholder because the fireball magic would be suppressed (just like any magic) and since the effect is instantaneous if the anti-magic Zone moved, then the fireball would not come back into existance, thus an anti-magic zone stops fireball cold.

Thank You all and have a nice day.

The cone is 150' long. That means, at the end of it it is pretty high up around 100' high. Thats a pretty big wall to get LoE around. Seeing as how ice storm is only 40' high it seems that the beholder is well protected.
UNLESS the AMF cone does not stop LoE. Which I think you are saying it does block LoE.
