Knight of the Wall

At 1st level, a knight of the wall gains the Shield Focus feat as a bonus feat. His cavalier levels count as fighter levels for the purpose of qualifying for all feats that list the Shield Focus feat as a prerequisite. This ability replaces tactician.

At 4th level, a knight of the wall specializes in using his shield to deflect attacks. He adds a bonus equal to his shield bonus to AC to his touch AC and his CMD, up to a maximum of half his cavalier level. He does not include any enhancement bonus he has from a magic shield in this calculation. This ability replaces expert trainer.

At 5th level, a knight of the wall uses his shield as a banner, though its benefits apply only to allies within 30 feet. This ability alters banner.

At 9th level, when carrying a shield, a knight of the wall adds a bonus equal to his shield bonus to AC on all saving throws against curse spells and effects, up to a maximum of half his cavalier level. He does not include any enhancement bonus from a magic shield in this calculation. This ability replaces greater tactician.

At 12th level, whenever a knight of the wall declares a challenge, his target must pay particular attention to him. As long as the target is within the threatened area of the cavalier, it takes a -2 penalty on attack rolls against anyone other than the knight of the Wall. This ability replaces demanding challenge.

At 17th level, when carrying a shield, a knight of the wall adds a bonus equal to his shield bonus to AC on saving throws against death spells and magical death effects, up to a maximum of half his cavalier level. He does not include any enhancement bonus from a magic shield in this calculation. This ability replaces greater tactician.
