You can overcome the magical protections of your enemies.

Prerequisites: BAB +3, Base Knowledge(Arcane) score 8 or Base Survival Score 8, Mage Slayer Style

Benefit: In the Mage Slayer Style even magic used a split second grants you an opportunity to retaliate. After using Mage Slayer Strike you watch your target for one turn, during this time period swift and immediate action spells and spell-like abilities from that target provoke an attack of opportunity from you.

Special: You cannot activate styles out of combat. Activating a style is a swift action and you can have solely one active style at a time.
