Smog is Azazel's death form. He is nothing more than a wisp of acrid black smoke. His only thought process at this time is to feed but fortunately his pull is weak and he can only draw a little life at a time. This form cannot be harmed as it is only smoke. This is Azazel's form at 0% health. It takes him a long time to build back up to enough strength to cocoon and burrow beneath the ground. At which point he will reform into the fawn and have to start the process of growth all over again. He hates this form more than anything and so fears 'death'.
