A device created by a Rondel born Imperial weapon designer who worked closely with various enchanters and metallurgists, it revolutionized warfare on the continent by providing some of the ability and power of a sorcerer's destructive tendencies and allowing any man to use and direct it. Composed of a 'chamber' which takes and contains a Testa typically sealed via a sliding mechanism or bolt lock. A 'striker' mechanism enchanted to break the Testa's seal is typically located under the chamber. The weapon is 'fired' by either a trigger like latch or a simple lever, the spell is then unleashed, contained and directed by a chamber that serves to both keep the spell away from the user as well as serve as a means of aiming. Skilled mages can use their abilities to change the resulting spell's direction once it exits the chamber.
