This Weapon may contain spoilers from the The Fall of Plaguestone Adventure

Source The Fall of Plaguestone pg. 56
Price 25 gp; Damage 1d8 P; Bulk 1
Hands 2; Range 30 ft.; Reload 1
Type Ranged; Category Simple; Group Bow

This crossbow can deliver alchemically infused bolts. The strange weapon has a metal bracket mounted on the side of the stock near the lath. As an action, you can load a single lesser alchemical bomb into the bracket; this bomb must be one that deals energy damage (such as an acid flask, alchemist’s fire, bottled lightning, frost vial, or thunderstone). The next three attacks made with the crossbow deal 1d6 damage of the bomb’s damage type in addition to the crossbow’s normal damage. If the second and third attacks are not all made within 1 minute of the first attack, the bomb’s energy is wasted. These attacks never deal splash damage or other special effects of the bomb and are not modified by any abilities that add to or modify a bomb’s effect. The addition of the bracket serves to unbalance the weapon, reducing its range to 30 feet. It otherwise functions as a crossbow (when determining damage, reload, and so on). Creatures use their crossbow proficiency when using the alchemical crossbow. The alchemical crossbow costs 25 gp.



Alchemical items are powered by reactions of alchemical reagents. Alchemical items aren’t magical and don’t radiate a magical aura.

Critical Specialization Effects

Source Core Rulebook pg. 283 4.0
Certain 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.
