Sneak Attack: If a rogue can catch an opponent when he is unable to defend himself effectively from her attack, she can strike a vital spot for extra damage.
The rogue's attack deals extra damage anytime her target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the rogue flanks her target. This extra damage is 1d6 at 1st level, and increases by 1d6 every two rogue levels thereafter. Should the rogue score a critical hit with a sneak attack, this extra damage is not multiplied. Ranged attacks can count as sneak attacks only if the target is within 30 feet.
With a weapon that deals nonlethal damage (like a sap, whip, or an unarmed strike), a rogue can make a sneak attack that deals nonlethal damage instead of lethal damage. She cannot use a weapon that deals lethal damage to deal nonlethal damage in a sneak attack, not even with the usual –4 penalty.
The rogue must be able to see the target well enough to pick out a vital spot and must be able to reach such a spot. A rogue cannot sneak attack while striking a creature with concealment.
Trapfinding: A rogue adds 1/2 her level to Perception skill checks made to locate traps and to Disable Device skill checks (minimum +1). A rogue can use Disable Device to disarm magic traps.
Evasion (Ex): At 2nd level and higher, a rogue can avoid even magical and unusual attacks with great agility. If she makes a successful Reflex saving throw against an attack that normally deals half damage on a successful save, she instead takes no damage. Evasion can be used only if the rogue is wearing light armor or no armor. A helpless rogue does not gain the benefit of evasion.
Rogue Talents: As a rogue gains experience, she learns a number of talents that aid her and confound her foes. Starting at 2nd level, a rogue gains one rogue talent. She gains an additional rogue talent for every 2 levels of rogue attained after 2nd level. A rogue cannot select an individual talent more than once.
Talents marked with an asterisk add effects to a rogue's sneak attack. Only one of these talents can be applied to an individual attack and the decision must be made before the attack roll is made.
Debilitating Injury (Ex): At 4th level, whenever a rogue deals sneak attack damage to a foe, she can also debilitate the target of her attack, causing it to take a penalty for 1 round (this is in addition to any penalty caused by a rogue talent or other special ability). The rogue can choose to apply any one of the following penalties when the damage is dealt.
Bewildered: The target becomes bewildered, taking a –2 penalty to AC. The target takes an additional –2 penalty to AC against all attacks made by the rogue. At 10th level and 16th level, the penalty to AC against attacks made by the rogue increases by –2 (to a total maximum of –8).
Disoriented: The target takes a –2 penalty on attack rolls. In addition, the target takes an additional –2 penalty on all attack rolls it makes against the rogue. At 10th level and 16th level, the penalty on attack rolls made against the rogue increases by –2 (to a total maximum of –8).
Hampered: All of the target’s speeds are reduced by half (to a minimum of 5 feet). In addition, the target cannot take a 5-foot step.
