Environmental
The area is on fire. Anything flammable is either already burning or will be soon.
Effect: All characters suffer a –2 to all rolls due to smoke and heat. After two turns, any character that breathes also suffers 2 bashing damage per turn due to smoke inhalation. After three turns, characters also suffer 1 lethal damage per turn from burns and must succeed on a Dexterity + Stamina roll each turn to avoid catching fire (see Chronicles of Darkness p. 98).
Ending the Tilt: Different types of fire require different methods to extinguish; in general, cutting off the fire from its fuel sources does the trick. Water, carbon dioxide, sand, and baking soda can be useful, depending on the size and type of the fire. Eventually all fires burn themselves out, but that can be cold comfort in the aftermath of a destructive blaze.
