Traits
Agile: The multiple attack penalty you take with this weapon on the second attack on your turn is –4 instead of –5, and –8 instead of –10 on the third and subsequent attacks in the turn.
Catfolk: A creature with this trait is a member of the catfolk ancestry. Catfolk are humanoids with feline features. An ability with this trait can be used or selected only by catfolk. An item with this trait is created and used by catfolk.
Deadly d8: On a critical hit, the weapon adds a weapon damage die of the listed size. Roll this after doubling the weapon’s damage. This increases to two dice if the weapon has a greater striking rune and three dice if the weapon has a major striking rune. For instance, a rapier with a greater striking rune deals 2d8 extra piercing damage on a critical hit. An ability that changes the size of the weapon’s normal damage dice doesn’t change the size of its deadly die.
Disarm: You can use this weapon to Disarm with the Athletics skill even if you don’t have a free hand. This uses the weapon’s reach (if different from your own) and adds the weapon’s item bonus to attack rolls (if any) as an item bonus to the Athletics check. If you critically fail a check to Disarm using the weapon, you can drop the weapon to take the effects of a failure instead of a critical failure. On a critical success, you still need a free hand if you want to take the item.
Finesse: You can use your Dexterity modifier instead of your Strength modifier on attack rolls using this melee weapon. You still calculate damage using Strength.
Versatile P: A versatile weapon can be used to deal a different type of damage than its listed type. This trait indicates the alternate damage type. For instance, a piercing weapon with versatile S can deal piercing or slashing damage. You choose the damage type each time you attack.
Critical Specialization Effects
Source Core Rulebook pg. 283 4.0Certain feats, class features, weapon runes, and other effects can grant you additional benefits when you make a Strike with certain weapons and get a critical success. This is called a critical specialization effect. The exact effect depends on which weapon group your weapon belongs to, as listed below. You can always decide not to add the critical specialization effect of your weapon.
Knife: The target takes 1d6
persistent bleed damage. You gain an item bonus to this bleed damage equal to the weapon's item bonus to attack rolls.
