Weapon and Armor Proficiency: Rogues are proficient with all simple weapons, plus the hand crossbow, rapier, shortbow, and short sword. Rogues are proficient with light armor, but not with shields.
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 any time 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 it 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. A rogue can’t strike with deadly accuracy from beyond that range.
With a sap (blackjack) 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, because she must make optimal use of her weapon in order to execute a sneak attack.
A rogue can sneak attack only living creatures with discernible anatomies—undead, constructs, oozes, plants, and incorporeal creatures lack vital areas to attack. Any creature that is immune to critical hits is not vulnerable to sneak attacks. 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 or striking the limbs of a creature whose vitals are beyond reach.
Trapfinding: Rogues (and only rogues) can use the Search skill to locate traps when the task has a Difficulty Class higher than 20. Finding a nonmagical trap has a DC of at least 20, or higher if it is well hidden. Finding a magic trap has a DC of 25 + the level of the spell used to create it.
A rogue who beats a trap’s DC by 10 or more with a Disable Device check can study a trap, figure out how it works, and bypass it (with her party) without disarming it.
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 (such as a red dragon’s fiery breath or a fireball), she instead takes no damage. Evasion can be used only if the rogue is wearing light armor or no armor. A helpless rogue (such as one who is unconscious or paralysed) does not gain the benefit of evasion.
Trap Sense (Ex): At 3rd level, a rogue gains an intuitive sense that alerts her to danger from traps, giving her a +1 bonus on Reflex saves made to avoid traps and a +1 dodge bonus to AC against attacks made by traps. These bonuses rise to +2 when the rogue reaches 6th level, to +3 when she reaches 9th level, to +4 when she reaches 12th level, to +5 at 15th, and to +6 at 18th level. Trap sense bonuses gained from multiple classes stack.
Disruptive Attack (Ex):
Replaces: If you select this class feature, you do not gain uncanny dodge at 4th level. Instead, you gain uncanny dodge at 8th level (when you would normally gain improved
uncanny dodge).
Benefit: Beginning at 4th level, through careful study you’re able to find exploitable flaws in any creature’s tactics and defenses. Whenever you hit a target that is flat-footed against your attack, or whenever you hit a target that you flank, you can choose to sacrifice your sneak attack damage in order to apply a –5 penalty to that creature’s AC for 1 round. Multiple hits on the same target don’t stack. This extraordinary ability works even against creatures normally immune to extra damage from sneak attacks, such as undead.
Uncanny Dodge (Ex): At 8th level, rogue can react to danger before her senses would normally allow her to do so. She retains her Dexterity bonus to AC (if any) even if she is caught flat-footed or struck by an invisible attacker. However, she still loses her Dexterity bonus to AC if immobilized. If a rogue already has uncanny dodge from a different class (a rogue with at least two levels of barbarian, for example), she automatically gains improved uncanny dodge instead.
Special Abilities: On attaining 10th level, and at every three levels thereafter (13th, 16th, and 19th), a rogue gains a special ability of her choice:
Feat: A rogue may gain a bonus feat in place of a special ability.
