Weapon and Armor Proficiency
Rogues are proficient with all simple weapons, plus the hand crossbow, rapier, sap, short sword, and shortbow. They are proficient with light armor, but not with shields.
Finesse Training (Ex)
At 1st level, a rogue gains Weapon Finesse as a bonus feat. In addition, starting at 3rd level, she can select any one type of weapon that can be used with Weapon Finesse (such as rapiers or daggers). Once this choice is made, it cannot be changed. Whenever she makes a successful melee attack with the selected weapon, she adds her Dexterity modifier instead of her Strength modifier to the damage roll. If any effect would prevent the rogue from adding her Strength modifier to the damage roll, she does not add her Dexterity modifier. The rogue can select a second weapon at 11th level and a third at 19th level.
Sneak Attack2d6
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 2 rogue levels thereafter. Ranged attacks can count as sneak attacks only if the target is within 30 feet. This additional damage is precision damage and is not multiplied on a critical hit.
With a weapon that deals nonlethal damage (such as a sap, unarmed strike, or whip), 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 total concealment.
Trapfinding
A rogue adds 1/2 her level on Perception checks to locate traps and on Disable Device checks (minimum +1). A rogue can use Disable Device to disarm magic traps.
Evasion (Ex)
At 2nd level, a rogue can avoid even magical and unusual attacks with great agility. If she succeeds at a 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.
Fast Stealth (Ex) Danger Sense (Ex)+1
At 3rd level, a rogue gains a +1 bonus on Reflex saves to avoid traps and a +1 dodge bonus to AC against attacks made by traps. In addition, she gains a +1 bonus on Perception checks to avoid being surprised by a foe. These bonuses increase by 1 every 3 rogue levels thereafter (to a maximum of +6 at 18th level). This ability counts as trap sense for the purpose of any feat or class prerequisite, and can be replaced by any archetype class feature that replaces trap sense. The bonuses gained from this ability stack with those gained from trap sense (from another class).
