Detect Evil (Sp): At will, a paladin can use detect evil, as the spell. A paladin can, as a move action, concentrate on a single item or individual within 60 feet and determine if it is evil, learning the strength of its aura as if having studied it for 3 rounds. While focusing on one individual or object, the paladin does not detect evil in any other object or individual within range.
Smite Evil (Su): Once per day, a paladin can call out to the powers of good to aid her in her struggle against evil. As a swift action, the paladin chooses one target within sight to smite. If this target is evil, the paladin adds her Charisma bonus (+2) to her attack rolls and adds her paladin level (+2) to all damage rolls made against the target of her smite. If the target of smite evil is an outsider with the evil subtype, an evil-aligned dragon, or an undead creature, the bonus to damage on the first successful attack increases to 2 points of damage per level the paladin possesses (+4). Regardless of the target, smite evil attacks automatically bypass any DR the creature might possess.
In addition, while smite evil is in effect, the paladin gains a def lection bonus equal to her Charisma modifier (+2) to her AC against attacks made by the target of the smite. If the paladin targets a creature that is not evil, the smite is wasted with no effect.
The smite evil effect remains until the target of the smite is dead or the next time the paladin rests and regains her uses of this ability.
Divine Grace (Su): At 2nd level, a paladin gains a bonus equal to her Charisma bonus (+2) on all Saving Throws.
Lay On Hands (Su): Beginning at 2nd level, a paladin can heal wounds (her own or those of others) by touch. Each day she can use this ability a number of times equal to 1/2 her paladin level plus her Charisma modifier (3). With one use of this ability, a paladin can heal 1d6 hit points of damage for every two paladin levels she possesses. Using this ability is a standard action, unless the paladin targets herself, in which case it is a swift action. Despite the name of this ability, a paladin only needs one free hand to use this ability.
Alternatively, a paladin can use this healing power to deal damage to undead creatures, dealing 1d6 points of damage for every two levels the paladin possesses. Using lay on hands in this way requires a successful melee touch attack and doesn't provoke an attack of opportunity. Undead do not receive a saving throw against this damage.
