Traits
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.
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.
Hampering: A weapon with the hampering trait includes a disruptive limb or flange. After you hit with the weapon, you can use an Interact action to give the target a –10-foot circumstance penalty to all Speeds. The penalty ends after the target takes a move action, at the start of your next turn, if you attack with the weapon, or if you move out of reach of the target, whichever comes first.
Reach: This weapon can be used to attack enemies up to 10 feet away instead of only adjacent enemies. For creatures with reach, the weapon increases their reach by 5 feet.
Uncommon: Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.

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.

prone unless they succeed at a Reflex save against your class DC.
