Summoned Creature casts an Antimagic Field

[Tristan Windseeker]

The Movanic Deva can be summoned using Summon Monster VI if a caster has the Summon Good Monster feat from Champions of Purity. This creature can create an Antimagic Field 1/day.

Normally, AMF interacts with summoned creatures as follows:

Quote:

Summoned creatures of any type 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 (The effects of instantaneous conjurations are not affected by an antimagic field because the conjuration itself is no longer in effect, only its result.)

However, if the summoned creature itself (such as the mentioned Movanic Deva) casts the antimagic field, things get a bit weird. The field first appears as a 10-ft.-radius emanation, centered on the Deva. The Deva then automatically beats its own Spell Resistance (as far as I can tell, you cannot choose to not automatically beat your own SR), and one of the following things happens...

1) An infinite loop. The Deva winks out, which winks out the Antimagic Field, causing the Deva to wink back in, causing the Antimagic Field to wink back in, which causes the Deva to wink back out...etc.
2) The Deva winks out and cannot return, but the Antimagic Field remains in place where the Deva cast it.

What is the correct answer?

3) The summoner has a stroke.

Read the short story "Convergent Series" by Larry Niven. It has all you need to know.

The Deva disappears for the length of the spell effect.

I'd treat the result as a blink spell. More accurately, I would have anybody trying to interact with the AMF or the Deva to roll percentile dice to see witch of the two they get.

Is there some rule that effects created by summoned creatures disappear if they do?

I don't think there is, but if there is then the antimagic field disappears as soon as the deva winks out. The deva reapears and there's no longer an antimagic field there.

If not, then the deva winks out and returns when the duration of the antimagic field is up.

Either way I'm not sure where the confusion is.

I like Zodin's idea. However, if this is in reference to a PFS scenario, the creature involved was not summoned, it was called.

Hmmm, a tricky one. The spell moves with its caster (and makes no exceptions for extraplanar relocation). However, a summoned creature is not 'really' there, and I don't think current spell effects remain in place when a summoned creature returns to the location it occupied before the spell was cast. I'd probably say that the spell A) turns off the summoning, B) which causes the deva's "spirit" to return to its home, C) which removes the antimagic field. Since summon monster is an effect centered on the consciousness of the deva (which is transplanted to a 'new body' and appears elsewhere, shown by the fact that it can be dispelled to banish the deva again - which would not be so if the spell stuck to the deva's actual body and was thus beyond the range of any dispelling), there is no spell effect on the deva's original body, and thus no spell calling the summoned deva back to the summoner.

I think.
