What would you think of a racial ability that prevented being in an anti-magic zone?

[SilvercatMoonpaw]

Anti-magic fields and the magical natures of some creatures bring a question to my mind: Are there any creatures in Pathfinder that absolutely can't exist inside an anti-magic field (whether because they only exist "because magic" or need magic to live/be animate)?

What if they were a PC race?

Tl;dr: What if there was a racial trait called "Can't enter anit-magic field"?

[LordKailas]

The only thing that comes to mind are summoned creatures. I seem to recall that if a summoned creature enters an anti-magic field they blink of out existence. But if the field goes away before the duration of the spell ends they re-appear.

But I could be mis-remembering.

What LordKailas said (and accurately recalls) plus:

I think you'd have to decide what happens when a PC or creature with such a trait is involuntarily place within such as area. Does Dead Magic have any effect on them i.e. count as an anti-magical region? Are they able to see or detect such an area or could they unintentionally enter?

'Absolutely can't' is somewhat akin to humans trying to enter an area utterly harmful to them such as swimming in lava, flying through outer space/the void or entering the Negative Material plane. Without magic to prevent it death will follow fairly rapidly if they are unable to remove or otherwise protect themselves. But obviously 'can't' doesn't quite apply either ... it'll just become immediately harmful/fatal to them if they do so and unless suicidal they won't voluntarily attempt to do so.

PS: footnote to the Summoned creature point above. If the creature is Summoned it will wink out upon entering or if there already can make an SR check. Creature such as Undead, Elementals or Outsiders are only effected if they are summoned but nothing prevents a Fire Elemental from existing there if they were not Summoned (popped out through a nearby portal and walked into the area, for instance)

[Fuzzy-Wuzzy]

Given that constructs work just fine in an AMF it'd take an awful lot of inherent magic for a race not to be functional within one. Any such race would probably also be destroyed by a successful dispel magic, which would suck extra.

You could have an allergy to abjuration. The creature would be sickened, because one of their ancestors was summoned long enough to sire offspring.
