Eyes in the Back of Your Head

(Complete Warrior, page 98, DnD 3.5)

[General]

Your superior battle sense helps minimize the threat of flanking attacks.

Prerequisite

WIS 13, base attack bonus +1

Benefit

Attackers do not gain the usual +2 bonus on their attack rolls when fl anking you. This feat grants no effect whenever you are attacked without benefit of your Dexterity modifier to Armor Class, such as when you are fl at-footed. You may still be sneak attacked when fl anked.

Normal

When you are flanked, the flanking opponents receive a +2 bonus on their attack rolls against you.
