what spells can penetrate an antimagic field?

[Dracorat]

Everything that bypasses SR should work fine. Acid arrow, for example.

Or use magic indirectly. You can buff yourself (true strike and the like) or use the environment to your advantage.

Sorry Kae, no dice. It doesn't have unbeatable spell resistance like some effects do (like the spell protection spells) it supresses all magic within. Spell text quoted below:

An invisible barrier surrounds you and moves with you. The space within this barrier is impervious to most magical effects, including spells, spell-like abilities, and supernatural abilities. Likewise, it prevents the functioning of any magic items or spells within its confines.

An antimagic field suppresses any spell or magical effect used within, brought into, or cast into the area, but does not dispel it. Time spent within an antimagic field counts against the suppressed spell’s duration.

Summoned creatures of any type and incorporeal undead wink out if they enter an antimagic field. They reappear in the same spot once the field goes away. Time spent winked out counts normally against the duration of the conjuration that is maintaining the creature. If you cast antimagic field in an area occupied by a summoned creature that has spell resistance, you must make a caster level check (1d20 + caster level) against the creature’s spell resistance to make it wink out. (The effects of instantaneous conjurations are not affected by an antimagic field because the conjuration itself is no longer in effect, only its result.)

A normal creature can enter the area, as can normal missiles. Furthermore, while a magic sword does not function magically within the area, it is still a sword (and a masterwork sword at that). The spell has no effect on golems and other constructs that are imbued with magic during their creation process and are thereafter self-supporting (unless they have been summoned, in which case they are treated like any other summoned creatures). Elementals, corporeal undead, and outsiders are likewise unaffected unless summoned. These creatures’ spell-like or supernatural abilities, however, may be temporarily nullified by the field. Dispel magic does not remove the field, though Mage's Disjunction might.

Two or more antimagic fields sharing any of the same space have no effect on each other. Certain spells, such as wall of force, prismatic sphere, and prismatic wall, remain unaffected by antimagic field (see the individual spell descriptions). Artifacts and deities are unaffected by mortal magic such as this.

Should a creature be larger than the area enclosed by the barrier, any part of it that lies outside the barrier is unaffected by the field.
Arcane Material Component

A pinch of powdered iron or iron filings.

Yep, that's why only instantaneous conjurations work, since they exist independant of the magic, that created them.

The orb spells are a border-case, though. The text for instantaneous conjurations is really meant for stuff like a Wall of Stone.

Sorry Kae, no dice. It doesn't have unbeatable spell resistance like some effects do (like the spell protection spells) it supresses all magic within. Spell text quoted below:

So it suppresses all magic. But I'm not talking about magic, only its effects, against which the field won't help:

An acid arrow (from Melf's spell) isn't magical. It was conjured up, which is a magical process, but once it's here, it's a perfectly mundane arrow with perfectly mundane acid on it.

And if you cast true strike and then shoot an arrow at someone, you aren't using a magical arrow, either, as the magical effect ends as soon as you shoot.

I'd argue that even shooting an arrow from a magical bow will grant you the enhancement bonus to both attack and damage, as the bow's the magical part here, and it never enters the field. It's a mundane arrow, just launched with more accuracy and power.

Finally, if you fireball this end of the bridge the guy in the field is standing on, he's sure to fall.

The draconic rat meant that part mostly.

Yep =)

Some of the critters that you can summon via the various summon spells may have ranged attacks that they can use from outside the antimagic to target those inside.

Perhaps a mephit breath weapon or a lantern archon light ray
You could have a flying creature pick up a rock and fly above the field and drop the rock
Don't think the range on a giant bombardier beetle acid spray is enough to be of use

superkurt13,

May we inquire as to why you'd want 1st to 4th level spells to penetrate an anti-magic field? Perhaps there is a magical solution to your problem we might be able to suggest if we knew the context of the situation...

 

[Kae'Yoss]

The draconic rat meant that part mostly.

Yeah. I guess, though, that most spells that don't allow SR are the kind who don't mind antimagic fields.

 

[Dracorat]

If by "don't mind" you mean "wink out of existance" then sure. =)

The other problem is whether AMF blocks Line of Effect or not.

From the 3.0 FAQ (pg. 53):
"the antimagic field blocks line of effect"
(I am unaware of any 3.5 change that would invalidate this clarification)

Also, from the Rules of the Game:
"An antimagic effect also blocks line of effect (see Chapter 10 in the Player's Handbook) for any magical ability"

and:
"some things that you can see through can block line of effect, such as a wall of force or an antimagic field."

and:
"The rules don't tell you what to do when whatever blocks the spread's line of effect isn't a solid object (for example, an antimagic field). "

and:
"Antimagic: A spell's magical effects become nonfunctional within an area of antimagic, such as an antimagic field. When a spell is aimed into an area of antimagic from somewhere outside the area, the antimagic blocks line of effect for the spell and the spell most likely fails."
