Devoted knight, divine agent, instrument of vengeance, peerless fighting machine—the crusader is a warrior dedicated to good, evil, law, chaos, or some other cause. She seeks out and destroys the enemies of her chosen faith. Strengthened by prayer or absolute devotion to a principle, armored by unshakable faith, and driven by her convictions, a good crusader is a mighty weapon against injustice and malice. An evil crusader, on the other hand, is a cruel and fearsome warrior of darkness.

Weapon and Armor Proficiency: As a crusader, you are proficient with simple weapons, martial weapons, light, medium, and heavy armor, and all shields.

Maneuvers: You begin your career with knowledge of five martial maneuvers. The disciplines available to you are Devoted Spirit, Stone Dragon, and White Raven. Once you know a maneuver, you must ready it before you can use it (see Maneuvers Readied, below).
A maneuver usable by crusaders is considered an extraordinary ability unless otherwise noted in its description. Your maneuvers are not affected by spell resistance, and you do not provoke attacks of opportunity when you initiate one. You learn additional maneuvers at higher levels, as shown on the above table. You must meet a maneuver’s prerequisite to learn it. 

Upon reaching 4th level, and at every even-numbered crusader level after that (6th, 8th, 10th, and so on), you can choose to learn a new maneuver in place of one you already know. In effect, you lose the old maneuver in exchange for the new one. You can choose a new
maneuver of any level you like, as long as you observe your restriction on the highest-level maneuvers you know; you need not replace the old maneuver with a maneuver of the same level. For example, upon reaching 10th level, you could trade in a single 1st-, 2nd-, 3rd- or 4th-level maneuver for a maneuver of 5th level or lower, as long as you meet the prerequisite of the new maneuver. You can swap only a single maneuver at any given level.

Maneuvers Per Encounter: You may use as many maneuvers per encounter as you know at your level.  

Steely Resolve (Ex): Your supreme dedication and intense focus allow you to temporarily set aside the pain and hindering effects of injuries. When an opponent strikes you, the injury does not immediately affect you. You have a delayed damage pool that allows you to forestall the effects of many injuries. This pool begins at 0 with each encounter. When you are attacked, any hit point damage the blow deals is added to your delayed damage pool. At the end of your next turn, you take damage equal to the total stored in your delayed damage pool, which then resets to 0. Any healing you receive can either increase your current hit point total as normal or reduce the total damage in your delayed damage pool. When you receive healing, you choose whether it affects your damage pool, your hit points, or both (you can split the amount of healing as you wish). Most crusaders opt to keep as much damage in their delayed damage pool as possible to maximize the benefit of their furious counterstrike ability (see below). Damage reduction does not apply to the damage that is received from Steely Resolve.
Special effects tied to an attack, such as energy drain, stun, and so forth, still affect you as normal, and their effects are not delayed by this ability. For example, if you are bitten by a venomous spider, you must still attempt a Fortitude save against the poison immediately, even though the bite damage shifts into your delayed damage pool. By the same token, any other special attack that imposes a condition, such as a medusa’s petrifying gaze, takes immediate effect on you.
At 1st level, your delayed damage pool can hold up to 5 points of damage. Any damage beyond that comes off your hit points as normal. The maximum damage your pool holds increases by 5 at 4th, 8th, 12th, 16th, and 20th level.

Indomitable Soul (Ex): Beginning at 2nd level, you draw upon the power of your unwavering faith to steel yourself against the enemies you face. Your personality, energy, and dedication to your faith make it possible for you to shrug off attacks that target your willpower.
You add your Charisma bonus (if any) as a bonus on Will saves. This bonus does not stack with that from a paladin’s divine grace ability.

Zealous Surge (Ex): Your boundless energy and dedication to your cause allow you to throw off the effect of a special attack, spell, or other attack that would otherwise hinder or harm you. Once per day, from 3rd level on, you can opt to reroll a single saving throw. You must abide by the result of the new, second saving throw, even if it is lower than the first. This ability does not require an action. You simply decide to use it after seeing the result of your saving throw roll but before the DM tells you if it fails or succeeds.

Smite (Ex): Driven by the courage of your convictions and the ironclad strength of your beliefs, you can strike back at those who dare stand against your cause. Starting at 5th level, once per day, you can concentrate all your anger, hatred, and determination into a single attack. On the next melee attack you make, you gain a bonus on your attack roll equal to your Charisma bonus (if any) and a bonus on damage equal to your crusader level. 

Die Hard (Ex): At 10th level, you gain Die Hard as a bonus feat.

Mettle (Ex): You can resist magical attacks with greater effectiveness than other warriors. Beginning at 13th level, by drawing on your boundless energy and dedication to your cause, you can shrug off effects that would hinder even the toughest warrior. If you succeed on a Fortitude or Will save against an attack that would normally produce a lesser effect on a successful save (such as a spell with a saving throw entry of Will half or Fortitude partial), you instead negate the effect. You do not gain the benefit of mettle when you are unconscious or sleeping.
