According to both the in-game description and what is listed on the Wiki, the following feats should grant additional Shield AC:
- Shield Block (Man-at-Arms)
- Shield Specialization: Light (General)
- Shield Specialization: Heavy (General)
- Shield Specialization: Tower (General)
However, they all provide Dodge AC instead.

Shield Block
Type of Feat: Class Ability
Prerequisites: Man-at-Arms 2nd level
Specifics: Your expertise with shields allows you to position it in such a way that a normally dangerous blow is deflected harmlessly. As you gain experience your competence with shield blocking increases and you gain additional shield AC while a shield is equipped. +1 at second level, +2 at 11th level, +3 at 21st level and +4 at 30th Man-at-Arms level. This bonus AC stacks with any permanent enchantment present on your shield or other forms of shield AC.
Use: Automatic

Shield Specialization
Type of Feat: General
Prerequisite: Shield proficiency
Specifics: You gain +1 Shield AC when using the selected kind of Shield. (Light / Heavy / Tower).
Use: Automatic
Gameplay notes: The shield AC stacks with other Shield AC, it normally would not. It also stacks with the Man-at-Arms shield AC bonuses.
This has a few side-effects:
- Dodge AC cap (20) is reached before it should
- The bonus AC is lost when flat-footed without Uncanny Dodge
- The bonus AC applies against Touch Attacks when it shouldn't
While the bonus AC against Touch Attacks is obviously good to have, it is out-shined by losing it when caught flat-footed.
