This is a collaboration technique that is usually used bewteen a kenjutsu specialist and a komodo dragon or any summon that utilizes poison. However, a single person should be able to use the technique if they have poison and are Water Release users.
After weaving the needed hand signals, the komodo dragon sprays some liquid on the sword's blade and reinforces it with chakra. The liquid contains a very toxic poison that can kill within minutes, cause acidic burning, and can even eat away at metal and concrete. The liquid is augmented by chakra to not only to prevent the poison from eating away at the blade, but the liquid can now gather water particles in the air and infuse it with itself, causing the liquid to slowly drip from the sword. The user's attacks with the sword are now more lethal. If the sword cuts into the opponent, the poison will travel from their wounds to vital organs faster than before, causing a quick death. It can also eat away at clothing and armor to remove defenses. The user can also release a spray of poison at the opponent with the sword when at a distance. The liquid's use of gathering atmospheric water keeps the sword from losing its poison when in battle.
