Machine Blitz
Machines go haywire when this ritual is cast. It takes effect instantly and lasts as long as the vampire concentrates on it. This ritual may be used to kill car engines, erase computer media, crash ticker-tape machines, stop life-support machines, et cetera. Essentially, Machine Blitz ceases any machine more complex than a rope-and-pulley. The thaumaturge must have a scrap of rusted metal in her possession for this ritual to work, though some vampires use a variant that requires a knot steeped in human saliva to be untied.
System: This ritual only stops machines; it does not grant any control over them. The effects of this ritual are invisible and not necessarily obvious - these things just seem to happen by coincidence.
