The new health system may help this technique gain unknown traction. Before, I would argue that any attack that lands an open wound on the target would result in their death 98% of the time, making this essentially useless. But now that we can sustain damage from attacks, that makes this a good late game jutsu. And what I mean by that is when people are running low on chakra and have taken multiple hits, they will both have open wounds and be more willing to engage in taijutsu, where this would excell. However, deciding that fateful blow is what will determine whether this has any real effect or not, still making it a disadvantage overall.
There is nothing really to tell about this technique. It's a variant of the poison mist jutsu from before, except less wide scale and a different poison. Tbh I'd add this to a list of Canon poisons before making it a technique lol.
This jutsu turns poisons into projectile weapons that release in two forms, liquid and gas. Very cool and very handy. It's a targeted range attack, so timing and setting up for it to land would be crucial, although not essential for success due to the gas element. This jutsu sets up the dilemma for your opponent, do I counter based on liquid poisons S/W or gas? With some thought, one could have a follow up combo ready for either scenario. This isn't to mention that this gives your bio access to poison smoke bombs, which could be utilized in basic Ninjutsu of the Ten Ten variety. Very useful, very cool, and I probably see myself using this more than I'd currently like to admit lol
