Traits
Forceful: This weapon becomes more dangerous as you build momentum. When you attack with it more than once on your turn, the second attack gains a circumstance bonus to damage equal to the number of weapon damage dice, and each later attack gains a circumstance bonus to damage equal to double the number of damage dice.
Propulsive: You add half your Strength modifier (if positive) to damage rolls with a propulsive ranged weapon. If you have a negative Strength modifier, you add your full Strength modifier instead.
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.
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.
Bow: If the target of the critical hit is adjacent to a surface, it gets stuck to that surface by the missile. The target is
immobilized and must spend an Interact action to attempt a DC 10
Athletics check to pull the missile free; it can't move from its space until it succeeds. The creature doesn't become stuck if it is incorporeal, is liquid (like a
water elemental or some
oozes), or could otherwise escape without effort.
