Student of War Abilities in Pathfinder: Wrath of the Righteous covers all the special abilities, be it passive or active, that one of the thirteen Prestige Classes of the game possesses.
Student of War Class Features/Abilities
At 7th level, the student can use Know Your Enemy ability as a swift action rather than a move action.
At 2nd level, when a student of war is using armor or a shield, she can use her Intelligence modifier in place of her Dexterity modifier for determining her Armor Class. The armor’s normal maximum Dexterity bonus still applies (limiting how much of the character’s Intelligence bonus she can apply to her AC).
At 3rd level, student of war can withstand even mental and unusual attacks with great will. If she makes a successful Will saving throw against an attack that normally deals half damage on a successful save, she instead takes no damage.
At 6th level, a student of war can aim her blows at the weakest point in a studied foe’s defense, ignoring up to 5 points of damage reduction. This does not apply to damage reduction without a type (such as DR 10/-). This ability cannot be used against creatures that are immune to critical hits or otherwise lack discernible weak points. This ability stacks with the Penetrating Strike feat.
At 9th level, once per day as a swift action, a student of war can focus on a weapon she holds and render it anathema to her studied foe. The weapon gains the bane special ability for 1 minute.
At 10th level, a student of war can find weak spots where none should exist. A student of war who uses her know your enemy ability can ignore the target's damage reduction and immunity to critical hits.
At 6th level, the student of war gets a +3 bonus to her critical hit confirmation rolls while in martial stance.
At 1st level and every two levels after, student of war gains one skill as a class skill.
As a move action, a student of war can study a foe she can see and attempt a Knowledge check appropriate to the creature's type. Success grants her a +1 insight bonus against her enemy, which can be applied via one of the following stances (chosen when the check is attempted) to the indicated statistics and rolls.
Defensive Stance: The bonus applies to Armor Class and on saving throws against the target's attacks. At 6th level, the student of war gets a +3 bonus to her AC against attacks of opportunity.
Martial Stance: The bonus applies on attack and damage rolls against the target. At 6th level, the student of war gets a +3 bonus to her Crit confirmation rolls while in Martial stance.
Tactical Stance: The bonus applies on combat maneuver checks and to CMD when initiating or defending against combat maneuvers.
A student of war can change her stance as a move action. The bonus increases to +2 at 4th level and +3 at 7th level.
At 7th level, the student can use this ability as a swift action rather than a move action.
At 2nd, 5th, and 8th levels, a student of war gains a bonus combat feat.
At 6th level, the student of war gets a +3 bonus to her AC against attacks of opportunity while in defensive stance.
