Where I have it that if a magic-based creature such as an Elf walks into a null magic zone it had better get out quick, as if it stays in it will certainly suffer and, given long enough, die. A Unicorn, being even more magic-based, would die much faster. A Dwarf, being less magic-based, would take longer to die. However a Human, as a non-magical creature, could build a house and live quite happily in there with her horse and dog.While I can't claim this is any sort of by-the-book interpretation, my own game use of antimagic field assumes that it shuts off the concentrated magical power of the sort that powers active spells and magic items, but does nothing to affect the low-level baseline magic that suffuses a fantasy world and allows dragons to fly, vampires to live, and high level fighters to survive falls off mountains.
