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.
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.
Tengu: A creature with this trait is a member of the tengu ancestry. Tengu are humanoids who resemble crows. An ability with this trait can be used or selected only by tengu. An item with this trait is created and used by tengu.
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.
Sword: The target is made off-balance by your attack, becoming
flat-footed until the start of your next turn.
