Lore Warden (Legendary Fighter Archetype)

Scholastic (Ex)
A lore warden gains 2 additional skill ranks each level. These ranks must be spent on Intelligence-based skills. All Craft and Knowledge skills are class skills for lore wardens, as are Linguistics and Spellcraft.

This ability replaces the fighter’s proficiency with medium armor, heavy armor, and shields.

Skillful Expertise (Ex)
At 2nd level, a lore warden qualifies for feats and other abilities as though she had the Combat Expertise feat. At 10th level, she gains Combat Expertise as a bonus feat, even if she would not normally qualify for the feat. If she already has Combat Expertise, she instead gains any one combat feat that includes Combat Expertise as a prerequisite (and for which she otherwise qualifies).

This ability replaces determination.

Maneuver Mastery (Ex)
At 3rd level, a lore warden adds his weapon training bonus on all CMB checks and to his CMD. This ability replaces the advanced armor training options gained at 3rd level and 7th level and the prowess options gained at 4th level and 8th level.

Enemy Assessment
At 7th level a lore warden gains access to the know thy enemy advanced weapon training option (see below). At 9th level if the lore warden has the know thy enemy ability he can replace an advanced armor training option to use his know thy enemy ability as a move action, and at 11th level he can replace a second advanced armor training option to also be able to use it as a swift action.

Know Thy Enemy (Ex)
When the lore warden succeeds at a Knowledge check to identify a creature’s abilities and weaknesses, he can also use a standard action to grant himself a +2 insight bonus on all attack and weapon damage rolls made against that enemy. This bonus lasts for a number of rounds equal to half his class level, or until the lore warden uses this ability against a different creature.

Crucial Avoidance
At 12th level, a lore warden gains access to the following prowess option:

Hair’s Breadth (Ex)
When subject to a critical hit, the lore warden can attempt an Acrobatics check to reduce the damage as an immediate action. If the result of this Acrobatics check is greater than the opponent’s confirmation roll then the lore warden negates the critical hit; the attack still hits and deals normal damage.

Know Weakness (Ex)
At 19th level, a lore warden can automatically confirm a critical hit once per round when he threatens a critical hit.

This ability replaces armor mastery.
