Improved Combat Casting

You can endure pain to finish your spell.

Prerequisite: Combat Casting, Concentration 6 ranks.

Benefit: You get a +4 dodge bonus to Armor Class against attacks of opportunity caused when you cast a spell. A condition that makes you lose your Dexterity bonus to Armor Class (if any) also makes you lose dodge bonuses. Also, whenever you are struck for damage during spellcasting the Concentration DC is reduced to DC10 + half the damage dealt.
