@The bolded part, what's the difference with regular gens? Also, is the rank increase only meant to justify breaking through gen deterrents ( and what do these deterrents entail, btw? Seals mostly? ) or does the pain needed to break it increase accordingly? I'll also assume it doesn't take extra time to apply this technique, right? It's performed at the same time as the gen tf-wise?
Basically, a gen empowering technique that is used in conjunction with the illusion for additional power and to possibly bait out a technique from the opponent. For example, whilst employing the Snake gen and Earth, the snake would look like it's a simple doton technique and not much different from a common restraining technique. The average RPer would use a lightning surge to free themselves but you could have followed with a water technique that is suddenly electrified, amplifying it's power.
On the other hand, Nagashi is a simple yet effective defense against illusions given it's an A-rank full body chakra surge. As such, if you were to imbue water to the snake gen, it would act as a deterrent to nagashi unless the opponent was looking for a quick death. Lightning/Wind snakes could be used in the same fashion, the only difference being what type of sensation the opponent experiences. I'd say lightning would give the feeling of numbness, whereas wind would make you feel as if the skin in contact with the snake was slashed away. Earth would feel heavy and solid whereas water should feel like most liquids do on the skin.
