MET LARP SRD

The paranoia elders feel toward technology was not merely a product of the information age; throughout history, vampires have met technological progress with suspicion and fear. This ritual is the product of their insecurities, rendering most forms of technology inert within a confined space.

To cast this ritual, you must draw magical runes in animal blood on each wall of a room no larger than 10 square feet for each dot of the Occult skill you possess. Thereafter, any item brought into the room (or that was in the room when this ritual was cast) that is more technologically complex than a crossbow ceases to function. Any object powered by electricity temporarily becomes useless and complex weapons such as guns will not fire. The Storyteller is the final arbiter of what is affected by a Dead Zone. 

A Dead Zone lasts for a-year-and-a-day. The blood used to create a Dead Zone does not fade until the ritual’s duration ends or the magical runes are destroyed.
