Hi there everyone. I need your help.

1. PHB says that conjured creatures get an SR check before being affected by Antimagic Field.

2. MoF (pg 77, and then cross-referred by PGtF) has a spell Antimagic Aura, one level higher, that is explicit: SR=Yes

When I read the PBH description, it is actually silent about SR more generally.

question: What are your views about whether or not a caster with SR should get a check to override Antimagic Field?

Precedents to Note

1. Also - I've seen two spells, this forum, that are "anti-antimagic fields" - and - in any case, all spells with physical effects (e.g. creating rocks above the targets head and then dropping them on the target in an antimagic field) work.

2. Add to that, the prismatic series, wall of force series (those spells that create "force" effects: Wall of Force, Forcecage) are immune.

3. Initiate of Mystra allows spells with Line of Effect to get through AMF.

4. Mordenkainan's Dysjunction

5. What about Wish?

regards

A caster does not get a SR check to use spells within an AMF. His items may recieve SR checks in order to continue operating within the field, and he may make a SR check to retain supernatural abilities (so long as they do not require line of effect, i.e. gaze attacks are out, but a celestial might keep tounges)

Sounds reasonable, but how do you form that conclusion. Do you have a written reference.

What about Initiate of Mystra (line of effect retained) in combination with SR checks.

Why don't you think spell effects are also SR checked?

:uh-huh:
What ?

There is no SR for antimagic field in any form.

As for Antimagic Aura, I am 100% sure the target to be affected gets SR to negate the spell, but still no SR of any kind is allowed to work magic within antimagic.

The ONLY exception to antimagic are artifacts and epic spells (which get chance to work).
Oh yes, I'm not familiar with new clerics of Mystra, but I heard they can do something within antimagic.

I'm going to leave out references to MoF, because I don't have it.
1. PHB says that conjured creatures get an SR check before being affected by Antimagic Field.Not quite true. Summoned creatures that are already in existence and have SR may use their SR to resist 'winking out'.

question: What are your views about whether or not a caster with SR should get a check to override Antimagic Field?

Precedents to Note

1. ... in any case, all spells with physical effects (e.g. creating rocks above the targets head and then dropping them on the target in an antimagic field) work.Assuming there is no magic functioning upon or otherwise guiding the projectile within the field, this works. I doubt you could 'create' the rocks (since unless the duration was 'Instantaneous' they'd vanish within the field), though you could use magical means to arrange for mundane falling rocks.

Note that an AMF is at once more potent and weaker than dispel magic. When a spell is dispelled, it immediately ends normally (eg see fly). An AMF instantly and (almost) totally suppresses all magics.

2. Add to that, the prismatic series, wall of force series (those spells that create "force" effects: Wall of Force, Forcecage) are immune.Be careful with your generalisations - the ability to block an AMF is a property of certain "wall" spells, not all force or all prismatic spells. For example, prismatic wall and prismatic sphere block an AMF; prismatic spray is suppressed as normal. Similarly wall of force and magic missile.

What is interesting is that the text states that an AMF "suppresses any spell or magic effect used within, brought into, or cast into the area, but does not dispel it". This very much looks to me that a spellcaster can cast a spell within an anti-magic field, but the effect won't happen if the 'target' is within the field. If the target later moves out of the field, the effect happens (as long as it has duration to do so). See D&D 3.0 FAQ, pg 53, which agress with this interpretation.

Note that secondary effects are suppressed, and don't apply. If you cast fireball from inside an AMF at targets outside the AMF, you cannot add +3 to the DC from your headband of intellect +6, since that effect is currently suppressed, and the DC bonus is calculated on your ability score at the time of casting.
3. Initiate of Mystra allows spells with Line of Effect to get through AMF.Given the above, I don't know what benefit this ability actually grants (and don't have MoF) to check. A caster can already cast line of effect spells through an AMF, and they will work just fine as long as the target isn't currently in the AMF.
4. Mordenkainan's Dysjunction
MDJ allows a 1% per caster level chance of dispelling the AMF (and only then anything within it). However, my reading of the rules suggests that the burst point of the MDJ must be outside the AMF and cascade back within it.
5. What about Wish?An instantaneous wish won't function in an AMF. These include wishes to undo misfortune, create stuff, increase ability scores, travel, heal (including resurrection), or dispel magic. Wishes may also duplicate lower level spells, but MDJ is 9th level. As DM, I'd allow a wish dispel an AMF, but only if the wish was cast [u]outside[/i] the AMF. If cast within the AMF, it would 'happen' but the effect would be suppressed and the wish wasted.

question: What are your views about whether or not a caster with SR should get a check to override Antimagic Field?Answer: no way, unless the caster is a pre-existing summoned creature and risks having their summoning suppressed by a just cast AMF.

Besides, the AMF doesn't stop you using magic, it just stops the magic you use doing anything with the AMF while the AMF if up. All the above precedents support this view; none support an SR check to make your magic happen.

A Spellguard of Silverymoon could use her Selective

So...
A Spellguard of Silverymoon could use her Selective Spell ability to make an AMF not affect some type(s) of creature inside its AoE?

I've no idea what that ability does. However...

An anti-magic field affects an area, and the thing that is affected is 'magic'. The only creatures that are directly affected are summoned creatures. Their very presence is maintained by magic; if the magic goes, so does the creature. All other effects on creatures are indirect results of magic being suppressed.
