Duelist Abilities in Pathfinder: Wrath of the Righteous covers all the special abilities, be it passive or active, that one of the thirteen Prestige Classes of the game possesses.
Dualist Class Features/Abilities
When wearing light or no armor and not using a shield, a duelist adds 1 point of Intelligence bonus (if any) per duelist class level as a dodge bonus to her Armor Class while wielding a melee weapon. If a duelist is caught flat-footed or otherwise denied her Dexterity bonus, she also loses this bonus.
A duelist gains the ability to strike precisely with a light or one-handed piercing weapon, adding her duelist level to her damage roll.
When making a precise strike, a duelist cannot attack with a weapon in her other hand or use a shield. A duelist’s precise strike only works against living creatures with discernible anatomies. Any creature that is immune to critical hits is also immune to a precise strike, and any item or ability that protects a creature from critical hits also protects a creature from a precise strike.
At 2nd level, a duelist gains a +2 bonus on initiative checks. At 8th level, the bonus increases to +4. This bonus stacks with the benefit provided by the Improved Initiative feat.
At 2nd level, a duelist learns to parry the attacks of other creatures, causing them to miss. Whenever the duelist takes a full attack action with a light or one-handed piercing weapon, she can elect not to take one of her attacks. At any time before her next turn, she can attempt to parry an attack against her or an adjacent ally as an immediate action.
To parry the attack, the duelist makes an attack roll, using the same bonuses as the attack she chose to forego during her previous action. If her attack roll is greater than the roll of the attacking creature, the attack automatically misses. For each size category that the attacking creature is larger than the duelist, the duelist takes a –4 penalty on her attack roll. The duelist also takes a –4 penalty when attempting to parry an attack made against an adjacent ally.
Starting at 3rd level, when wearing light or no armor and not using a shield, a duelist gains an additional +4 bonus to AC against attacks of opportunity caused when she moves out of a threatened square.
You may make a number of additional attacks of opportunity per round equal to your Dexterity bonus. With this feat, you may also make attacks of opportunity while flat-footed.
At 4th level, a duelist gains an additional +2 competence bonus on all Reflex saving throws.
Starting at 5th level, a duelist can make an attack of opportunity against any creature whose attack she successfully parries, so long as the creature she is attacking is within reach.
At 6th level, a duelists movement speed is no longer reduced on difficult terrain. Depending on the circumstance, she may still need to make appropriate checks to move over the terrain.
At 7th level and higher, if a duelist chooses to fight defensively or use total defense in melee combat, she gains an additional +1 dodge bonus to AC for every 3 levels of duelist she has attained.
At 9th level, a duelist gains the benefit of the Deflect Arrows feat when using a light or one-handed piercing weapon. The duelist does not need a free hand to use this feat.
At 9th level, enemies adjacent to the duelist that take a withdraw action provoke an attack of opportunity from the duelist.
When you confirm a critical hit using a light or one-handed piercing weapon, you can apply one of the following penalties in addition to the damage dealt: reduce the target's movement speed by a half, 1d4 points of Strength or Dexterity damage, –4 penalty on all saving throws, –4 penalty to Armor Class, or 2d6 points of bleed damage. These penalties last for 1 minute, except for ability damage, which must be healed normally, and bleed damage, which continues until the target receives magic healing or leaves combat.
