@Crane__ Yo so, Poison Ninjutsu is special in the sense that it has multiple states, unlike most elements. These forms have different strengths and weaknesses which is important in combat because you are able to use certain techniques as either a liquid or a gas. These substances have different properties and thus interact with things, such as solids, liquids, gases, fire, lightning etc differently. Let's look them over and see if we can pick out the advantages of using one over the other in combat. At least to get you started and familiar with Poison Release.
Poison
Strong to: In liquid form, Poison is strong to Fire, requiring one rank higher to turn it into it's gaseous form and causes it's effects to speed up if inhaled. In gas form, it is strong to Lightning.
Weak to: In liquid form, Water and Earth are good counters to contain and dilute the poison. While in gaseous form, Wind is highly effective.
As you can see, poison as a substance comes in
two basic forms, liquid and gas. These forms are their states of matter and heavily affect their strengths and weaknesses. A good way to think of this is to visualize, water, water can be a liquid, a solid; ice, or even a gas; vapor or steam. We'll talk about
gaseous poison first. It's similar to wind, in some regards, but the fact that
it usually has additional symptoms is what makes it better and more useful than wind release.
Gaseous poison is strong to lightning for the same reasons wind is strong to lightning. It can work as an insulator containing and breaking the lightning down through an elemental interaction between the two. This means a gaseous poison technique can nullify and snuff out a lightning technique one rank higher, or overpower a technique of the same rank
as an example, a C-rank gaseous poison technique could deal with a B-rank lightning technique on equal terms. If instead, we pit a B-rank gaseous poison technique against a B-rank lightning technique the gaseous poison technique would
overpower the B-rank lightning technique leaving behind a C-rank remainder for the gaseous poison technique. However, gaseous poison is
weak to wind release. This is because the wind can blow away, and move the usually less dense and less abundant poison scattering it.
For gaseous poison, your main objective is to get your opponent to breathe it in. Some gaseous poisons can travel through the pores of the skin but for most applications,
the main drawback of gaseous poison is the fact that if your opponent doesn't breathe it in, the symptoms won't take hold.
Liquid poison is strong to fire but it also has a tricky application that very few elements have. This fact is one of my favorites about liquid poison because it means you can mess with your opponent. For example, let's say you used a C-rank liquid poison technique to defend from the B-rank fire technique.
The liquid poison would be able to nullify the fire technique, and it would change its state of matter from liquid poison to gaseous poison. So after the two techniques clashed, and acted upon one another what would be left would be a gaseous mist of damage-less poison. Meaning you are able to still poison your opponent even after your chakra is gone from the technique. Onto its weaknesses,
liquid poison is weak to water, because the water can dilute the poison,
and weak to earth because it can contain and stop the liquid from moving. For liquid poison,
your main objective is to get some onto your opponent's skin or into a wound as it can usually travel through their skin or the site of a wound and poison them. It can also be applied through injuries such as cuts making it very good to apply to your weapons.
All custom poison techniques can have both physical damage or side-effect based damage as well as various detriments.
Do you got all of that, or do you have any questions?
