Prerequisites: Disruptive, 10th-level fighter.

Benefit: Enemies in your threatened area that fail their checks to cast spells defensively provoke attacks of opportunity from you.

Normal: Enemies that fail to cast spells defensively do not provoke attacks of opportunity.

Endzeitgeist Says: Add insult to injury when foes fail their spellcasting - great!
