Psystorms
Source GM Core pg. 100
A psystorm is a magical weather pattern that occurs on some planets. Winds that howl with alien voices, sudden flashes of color and sound, and other bizarre phenomena accompany psystorms. Creatures without shelter take minor to moderate mental damage each minute during a psystorm. There's also a chance that a character might be struck by a bolt of magical energy during a psystorm. An energy bolt usually deals moderate damage of a randomly determined type.
