Okay one on contact poisons just exist in real life and in Dresden files there's just an outsider material called mordite that just is poisonous so much so that it causes death on contact.
Active defenses and armor. Contact poisons on the face of the stone idol covering our shoulder do nothing. If they have to break armor to touch bare skin they have to get past soak.
Contact poisons that kill you on the spot are rarer than you're presenting them to be, and just demonstrating that an extremely rare magical substance exists which could harm us doesn't actually change the equation here at all.
I'm also not going to quibble about the fact of proper lab procedure just exists I don't know if you ever went to high school chemistry but they taught you how to safely handle chemicals at least mine did, be in place with high ventilation, keep your equipment clean and clear, understand what chemicals you're working with and how they interact
That isn't what I meant and I'm almost certain you know it.
High school lab procedures aren't sufficient to make highly concentrated chlorine gas and not screw up. Doing this safely in significant quantities isn't a trivial task even with the aspects that can be offloaded to civilization as a whole.
It is possible to do this, it is not possible to do it trivially.
That's the over problem with your entire argument, you're not putting enough thought into the practical details of things and just making convenient simplifying assumptions.
It really seems like you have a problem more with Alchemy 1 being capable of doing that rather than my point but that's neither here nor there.
Then why have you consistently pushed it as the basis for super poisons being a threat?
Mundane poisons that could be a problem do exist and we've talked about them, but I just quoted the argument you've been making. It wasn't incidental to your fear mongering then.
So I will reiterate my point we are uniquely vulnerable to poison. I would like to not be hence the marble. I believe none of our opponents are above using poison and are in fact well disposed in the practice of using it.
Mine is that exalts are in fact extra resistant, and all the factors that make using chemical weapons hard in canon are significantly more difficult to overcome when they're involved as well.
It could be a threat, but not with the ease you're suggesting. The fact that people don't do this all the time is instructive on the issues involved.
