Wpn/Arm Prof: The Ironclad gains proficiency with Simple and Martial Weapons as well as with Shields (including tower shields). (Note: They do not gain armor proficiency because the feat Heavy Armor Optimization requires Heavy Armor Proficiency)

Ironbound (Ex): While wearing medium or heavy armor, the Ironclad reduces the armor check penalty and increases the Max Dex Bonus of their armor by their Str bonus (if any).

Additionally, the Ironclad is able to move at full speed in medium and heavy armor, as if it were light armor, and may sleep in medium or heavy armor without penalty.

Tough as Nails (Ex): At each level, the Ironclad gains Toughness as a bonus feat. Additionally, while wearing medium or heavy armor, the Ironclad increases the Armor bonus of their armor by 1 for every two instances of Toughness they possess.

Metallicize (Ex): Starting at 2nd level, at the start of each turn while wearing medium or heavy armor, the Ironclad gains temporary hit points equal to the Armor bonus of their Armor + 1 for each instance of Toughness the Ironclad possesses. These temporary hit points last until the start of the Ironclad's next turn.

Barricade (Ex): Whenever a 3rd level Ironclad fights defensively, uses the total defense action, or uses combat expertise to gain at least +2 to their Armor Class, they increase the duration of any Temporary Hit Points they possess by one round and may stack Temporary Hit Points they gain for that round.
