Do any Pathfinder supplements have a gas mask?


Homebrew and House Rules


I need one. If no supplements have one, does anyone have any suggestions for what a WW1 era gas mask should do in Pathfinder terms? Total immunity? Save bonus? How large should the penalty to perception be? Should your line of sight be effected?

Alternatively, a magic item that casts some sort of gust of wind spell, or even just provides it's own air supply.

EDIT: It should be known that this isn't a truly legitimate item, as I believe it was user created.

If a penalty to vision is there, i'd suggest no more than a -2, a -4 if it has shaded goggles.

You could also try checking the ravenloft books, as I think there was also a rudimentary gas mask in there.

Thanks. I think I'll hand out shaded ones that give out a -4 to sight based perception checks and a -2 to hearing based perception checks. If donned hastily, it has a 15% chance not to function properly.

Typically, at least modern masks, don't have any hearing diminishing effects. Since the mask is just that, it doesn't cover the ears, and this creates no penalty to hearing. Granted older ones might be hoods of some sort, since they might not have rubber/something similar to easily cover the gaps.


You can look at the doctor's mask in the second volume of curse of the crimson throne.

As a matter of fact, a modern mask (or a mask from WW1) should probably grant total immunity, there should be magic mask in Golarion which grant total immunity, and a mundane mask in Golarion should only gives a bonus.

Also note that holding your breath doesn't prevent a cloudkill to affect you. I don't think a mundane mask can work against such a spell.

I'm not using a spell. I'm using chlorine gas. Total immunity with donning hastily giving a 15% failure chance it is.

A gas mask would not provide complete protection from chlorine gas. Any exposed water would react with the chlorine and turn into hydrochloric (as well as hypochlorous) acid. Of course, keeping the gas out of your lungs is a priority, but it won't protect you completely - for example, any sweat on your skin will react with the gas and turn to acid.

I'd say that against something like chlorine, a gas mask would provide +4 to the Fort save as well as the equivalent of evasion.

Early WW1 masks were hoods, but the one I'm handing out (small box respirator) seems to leave the ears free. No hearing penalty it is.

It does that if it gets into the lungs, but I've never heard of sweat being acidified. In fact, even a wet cloth is somewhat effective against chlorine. That's why chlorine was replaced with phosgene and mustard gas during WW1. I want to use chlorine because it isn't overly efficient. Phosgene is worse because you cannot detect it easily and it can take over 24 hours to manifest symptoms, whereas mustard gas can injure through contact with bare skin. I want to gas the PCs, but I don't want to slaughter them.

The effects of sweat on exposed skin being acidified would be far less than having the humidity in the membranes in your lungs be, especially if you aren't exerting yourself and thus not being particularly sweaty. Less fluid, and the fluid is in a far less dangerous place. That's why I'd give a pretty hefty bonus to the save, as well as "mettle" (the Fort equivalent of evasion). But it's not like you could put on a gas mask and nothing else and walk through a room filled with chlorine and not be affected by it at all.

Points if you get the reference.

Simplicity is key, but gas masks predicate two types of poisonous gas. Those that must be breathed in and those that simply must touch your skin. Define poisonous gas' as such then allow the mask to bypass breathable and not exposed.

Another option would be to have the gas mask grant DR against breathable/airborn poisons or allow it to absorb a set amount of ability damage. That way the really nasty stuff remains nasty and you could justify carrying additional filters.

Just some thoughts.

I didn't get it.

There are some things like mustard gas I could throw around that can harm with contact, and phosgene is incredibly difficult to detect, so a gas mask that gives immunity to inhalants isn't a foolproof method of protection.

Could I please get a link to more information? I've always understood gas masks to be perfectly adequate against chlorine, which is why mustard gas and phosgene were placed into use.

Ah. As much as I love British television, I never did get into Doctor Who.
