Group CrossbowAmmunition Repeating Heavy Crossbow Magazine
This large crossbow has an internal chamber that can be loaded with up to five bolts. While it uses the same automated catch mechanism as other repeating crossbows, a repeating heavy crossbow's design has significant trade-offs. It has increased range and damage and is easier to learn how to use, but requires a small amount of effort to reload.
Traits
Repeating: A repeating weapon is a type of ranged weapon with a shorter reload time. These weapons can't be loaded with individual bolts or bullets like other crossbows and firearms; instead, they require a magazine of specialized ammunition to be loaded into a special slot. Once that magazine is in place, the ammunition is automatically loaded each time the weapon is cocked to fire, reducing its reload to the value in its reload entry (typically 0). When the ammunition runs out, a new magazine must be loaded, which requires a free hand and 3 Interact actions (to remove the old magazine, retrieve the new magazine, and slot the new magazine in place). These actions don't need to be consecutive and are the same as Interacting to reload.
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.
Crossbow: The target takes 1d8
persistent bleed damage. You gain an item bonus to this bleed damage equal to the weapon's item bonus to attack rolls.
