User can generate, create, emit or otherwise produce poison/poisonous substance and somehow inflict the victim. For the sake of clarity: poison, toxin and venom are terms for any substance that injures the health or destroys life when absorbed into the system: poison is the general word, toxin is a poison produced by an organism (plant, fungus, animal); it is especially used in medicine in reference to disease-causing bacterial secretions, venom is especially used of the poisons secreted by certain animals, usually injected by bite or sting.
