Thwart Foul Magic (Ex)

At 4th level, whenever a Knight of Ozem threatens an undead spellcaster, he gains the benefits of the Disruptive and Spellbreaker feats. He counts as having these feats for the purposes of qualifying for feats or other abilities. If he already possesses the Disruptive and/or Spellbreaker feats, the effects do not stack. When he threatens any spellcaster (not just an undead spellcaster), the concentration check DC increases by 2 if the spell being cast is from the necromancy school, has the death descriptor, or has the evil descriptor. For the purpose of this ability, the Knight of Ozem counts as having automatically identified the effect as if he had made a Spellcraft check. This increase only applies if the Knight of Ozem is aware of the spellcaster’s location and is capable of making an attack of opportunity.
