Bardic Knowledge (Ex)
A bard adds half his class level (minimum 1) to all Knowledge skill checks and may make all Knowledge skill checks untrained.
Bardic Performance
A bard is trained to use the Perform skill to create magical effects on those around him, including himself if desired. He can use this ability for a number of rounds per day equal to 4 + his Charisma modifier. At each level after 1st a bard can use bardic performance for 2 additional rounds per day. Each round, the bard can produce any one of the types of bardic performance that he has mastered, as indicated by his level.
Starting a bardic performance is a standard action, but it can be maintained each round as a free action. Changing a bardic performance from one effect to another requires the bard to stop the previous performance and start a new one as a standard action. A bardic performance cannot be disrupted, but it ends immediately if the bard is killed, paralyzed, stunned, knocked unconscious, or otherwise prevented from taking a free action to maintain it each round. A bard cannot have more than one bardic performance in effect at one time.
At 7th level, a bard can start a bardic performance as a move action instead of a standard action. At 13th level, a bard can start a bardic performance as a swift action.
Each bardic performance has audible components, visual components, or both.
If a bardic performance has audible components, the targets must be able to hear the bard for the performance to have any effect, and many such performances are language dependent (as noted in the description). A deaf bard has a 20% change to fail when attempting to use a bardic performance with an audible component. If he fails this check, the attempt still counts against his daily limit. Deaf creatures are immune to bardic performances with audible components.
If a bardic performance has a visual component, the targets must have line of sight to the bard for the performance to have any effect. A blind bard has a 50% chance to fail when attempting to use a bardic performance with a visual component. If he fails this check, the attempt still counts against his daily limit. Blind creatures are immune to bardic performances with visual components.
Aura of Good (Ex)
The power of a paladin's aura of good (see the detect good spell) is equal to her paladin level.
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 Cha bonus (if any) to her attack rolls and adds her paladin level 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. 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 deflection bonus equal to her Charisma modifier (if any) 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. At 4th level, and at every three levels thereafter, the paladin may smite evil one additional time per day, as indicated on Table: Paladin, to a maximum of seven times per day at 19th level.
