Defensive Study (DnD Feat)

Allows you to use your Intelligence modifier instead of your Dexterity modifier for armor class adjustments.

Prerequisite: 2 ranks of Sense Motive, Alertness

Benefit: Grants you the ability to substitute your Intelligence modifier for your Dexterity modifier when calculating armor class against a single opponent. To gain this benefit, you must be able to assess your opponent completely for at least three rounds of combat. During this period of study you are only able to take a partial action each round. Through the study of attack patterns you understand the best ways to avoid the attack methods used by your opponent.
