So...I've coming up with ideas for some devices the party took from the lair of a space worm (that might be the genesis of the ashen worm!) and I'm brainstorming some ideas.

I'm stealing ideas from The Lost Room.

One object sublimates brass.

I'm thinking that one device will sublimate metals. The kind based on a setting. It can also plate object with the metal on top of the device.

In the mini series the characters step back from the object when it starts sublimating brass, "I don't want to inhale metallic gas, do you?"

So, now I'm thinking of how to treat metallic gases :-)

Ingestible III looks like a decent level of lethality but survivability and onset time. You should be able to recognize you are breathing something odd but it will take a bit to notice it.
