Anti-Magical
Magic never behaves normally around this person, and spells, friend or foe alike, sometimes simply fail to take hold at all.
Magic has never worked quite right around you. Perhaps you have become a magic-user in spite of that, or perhaps you use your unique ability to fight magic-users.
Choose two attribute boosts. One must be to Constitution or Wisdom, and one is a free attribute boost.
You're trained in a Lore skill of your choice, though it can't be about a magical subject (as determined by the GM if it's unclear). Whenever you would be affected by magic, even your own magic or that of an ally, the originator of the effect must attempt a DC 3 flat check.
On a failure, the magic doesn't affect you (though it still has its normal effects on anyone else). On a success, the magic affects you and there is no need to attempt further flat checks for the same magical effect, even if it affects you again later.
