Type: General, Fighter
Source: Player's Handbook
You are adept at dodging blows.
Prerequisite: Dex 13
Benefit: During your action, you designate an opponent and receive a +1 dodge bonus to Armor Class against attacks from that opponent. You can select a new opponent on any action.
A condition that makes you lose your Dexterity bonus to Armor Class (if any) also makes you lose dodge bonuses. Also, dodge bonuses (such as this one and a dwarf's racial bonus to dodge giants) stack with each other, unlike most other types of bonuses.
