So for the poison detailed in the Contract, is there a time it takes for the poison to take place? It just says how long they have for an antidote. Also, the reductions are insane, -4 tiers at Epic constitution? That's like, double S-Rank worth of reductions. Is this the generic poison for all of the Salamanders?
Ibuse is able to release a Poison Mist from its mouth, which is capable of making the entirety of a victim's body numb just moments after inhalation and may eventually prove fatal, although these effects can be counteracted with the correct antidote. The poison must first be generated and then stored for a total of five minutes within Ibuse's body before it can be expelled again.
Ibuse is capable of concealing itself and navigating underground. It can then resurface beneath Hanzō's enemies and swallow them, trapping them in its mouth until they have succumbed to the fatal effects of the poison.
This is the abilities of the Canon Salamander contract. In canon this poison was uncounterable once it hit. I did not think that was kosher - hence my scaling. If you inhaled it you were paralyzed. You could get an antidote, but the most anyone who inhaled it could do is stumble to their feet. It has no other effects and can only be used once every five posts... which limits its usage to once or twice. If you dodge the poison you likely won't have to worry about it until the summon is already dispelled- or you get ample time to kill the Summon, the Summoner, or to flee the battlefield.
Are its effects potent? Yes. They're supposed to be. Otherwise they have no value at all.
Are they OP? No. They have counters. Earth Release lets you go underground and avoid the poison. Wind Release can potentially blow the poison gas away. You can run from the gas's range (it's listed as short-mid range in the wikia so we can give it a 20m range). You can possess some kind of item that lets you filter out the gas like the Samurai in canon. Kaito used to possess such an item.
Here is our sites poison system and their scaling:
Journeyman – Poisons of a journeyman level are costly, take more time to synthesize, but will kill their opponent far more quickly. Assume around a five-six turn kill time for a standard poison (ie something applied to a blade). At this level, poisons can begin to gain effects leading up to the “poison payload”, ie on turn 1 this happens, on turn two this happens, etc. Adding these abilities in may increase kill time on a case by case basis.
Ibuse's poison is supposed to be a Master-Level poison, but I scaled it it fit a more Journeyman level poison.
Anyways I gave all the effects a timer. The Epic Constitution/Legendary Constitution effects are debuff over time now for every other post meaning it takes a total of six posts to fully apply (which is extra time to kill the summon, the summoner, or flee the battlefield). Keep in mind I'm doing these things despite feeling I shouldn't have too as the amount of counters that exist to this thing are astounding. If I hit you with a B rank Lightning Gian I can pierce your skull and kill you. :/ If I hit you with a B rank Fire Dragon Bullet I can literally burn you to ash. If I hit you with a B rank water dragon I can crush your bones with substantial force.
I see no reason why the effects of this should be any less potent.
