It's REALLY easy to make in lethal quantities... You just need some rock salt, (NaCl, aka common 'table' salt) water and electricity to synthesize it, plus your container. As for weaponization, realize that the stuff, as typically produced, is already a poison that is suitable for weaponization. All that weaponization of chlorine means is that you've built a system to disperse it in atmosphere. That's not hard to do. Fans work, as do bombs of a certain type. The concentrated stuff would be DC 15-17 to make with such a system.However, I think you're all underestimating the damage. This was one of the most widespread means of chemical attack in WWI, along with mustard gas, which is a chlorine-containing compound. They are both rather lethal, though somewhat obvious when used.I would use something like this: Fort save: DC 20Damage: 1d6 Con, 3d8 Con(it's not immediately lethal, but after a minute minute or so, chances are you'll be dead or nearly so.)As a result, this should have a high PDC, to render it inline with most other poisons, but... it's actually really cheap to make. The main problem with giving it a low PDC is that it's not readily available in mass quantities, and storage is somewhat difficult, due to it's reactivity. It should probably be PDC 12-16 (it'll take some searching, but it's cheap...) or so.However, for various reasons, I'd give it a Lic (+1) restriction at the least, possibly even increasing to Res (+2), as owning it in mass quantities will incur some regulatory hassles and oversight (OSHA-type groups, the FBI, the EPA, and various police agencies) and thus, you probably don't wanna buy it too often. Most people who need it in large quantities are prone to recycling it if possible, synthesizing their own, or buy it in extreme bulk. Therefore, quantities in the level most PCs would have access to would in fact be signs of it being used for terrorist-type activities. (However, there are more effective poisons, some of which are just as easily made.)EDIT: to point out just how dangerous this stuff is, my chemistry professors (my being a chemistry student in a university, I've had a few of them) have lists of various chemical experiments. One of them involves reacting pennies with hydrochloric acid to produce copper (II) chloride. It's not a safe one to do, because even with a small (2-3, IIRC) number of pennies per person, the chlorine produced is enough to kill ~30 people easily, and very easy to produce. Once you're moving into the multi-kilogram range, you're talking warhead-worthy.Plus, it has a nasty side ability apart from burning your lungs.. it asphyxiates you, being heavier than air. Asphyxiation is nasty.</blockquote>
