"The Diffuser is a clockwork marvel equipped with a ripspike launcher and a sophisticated arcane relay. The individual ripspikes bear tiny fins controlled by a clockwork mechanism. This allows the arcane relay to adjust the trajectory of each ripspike, maximizing the probability of every shot striking true. The relay sends similar signals to other vectors, clockwork vessels, and priests of Cyriss to direct their efforts toward targets marked for immediate termination." - Privateer Press
