By taking his mask of and using Decay Release, Ryuk Levi sprays a purple foggy mist out of his mouth that spreads around the area. The fog is a substance made by Decay Release that eats up the insides of a person that inhales the fog, it eats everything, it starts off with your lungs, and then goes to your throat cutting off your breathing system. It takes about 30 minutes and is a sure kill, unless you have the antidote which is nearly impossible to get. You can wear a gas mask to protect your self from the fog, or just try and hold your breath.
