Thank you, now I have no doubts.

Hi everybody. How Noxious Poison (p. 244 Corebook) work with ninjutsu such as Deadly Sting and Noxious Cloud (p. 226-227 Corebook)? Do poison enchance the severity of the critical strike, which can be inflicted for the opportunity? As i see, with Deadly Sting this poison increase only physical damage by amplifying deadliness of weapon. Am i right? But then using it with Noxious Cloud doesnt make sense because we dont have any weapon with deadliness here.
