Mage Slayer

You have studied the ways and weaknesses of spellcasters and can time your attacks against them expertly.

Prerequisites: Spellcraft 2 ranks, base attack bonus +3.

Benefit: Spellcasters you threaten take a penalty on their Concentration checks made to cast spells defensively. This penalty is equal to your base attack bonus.

Special: Taking this feat reduces your caster level for all your spells and spell-like abilities by 4.
