This weapon can be used to launch vials of alchemical substances great distances much like a regular crossbow.
Description: The most common form of this weapon superficially resembles a crossbow without a bow. The other is simply the magazine and firing mechanism which is then installed on the underside of an existing crossbow. Both versions bear a rotating metal cylinder with ten chambers. Each chamber can hold up to five spellvials or alchemical splash weapons.
Activation: Loading a spellvial or alchemical splash weapon into a chamber is a standard action that provokes attacks of opportunity. Each of the ten chambers can hold up to five vials in any combination. Vials are fired from a chamber in the order they were loaded.
Rotating a chamber into firing position is a swift action that does not provoke attacks of opportunity. The topmost chamber of a vial launcher is considered to be the primary firing chamber and the weapon fires vials in this chamber until the chamber is empty, at which point another chamber containing vials must be rotated into firing position.
You can launch as many vials in a round as you have attacks, just as if you were using a repeating crossbow. A vial launcher has a maximum range of 150 feet and no range penalties.
