Forbidden Arcana introduced an atomizer that grants a RAW way to make alchemical compounds with a contact trigger that would normally require a command trigger.

So, two questions:
1) Does it allow any health category alchemy to be made as a contact trigger?  Or is this effect limited to just those preparations with the compound tag for some reason?

2) Does the prep have to be applied via the atomizer, or can you just use the atomizer during the creation process in order to get its contact-trigger effect?

If both questions should get the less restrictive answers, then that means we can actually make/buy/sell RAW-legal health potions, etc.  If not, well... then we need new RAW. ... Still.

1) Yes

2) Yes: "The nature of the atomizer itself keeps contact with the device from activating the contact trigger."
So you need the atomizer to apply the preparation as pulling the trigger substitutes the command

What it really turns on is the line
"Compounds made with a contact trigger are not enacted until they contact a substance after being fired from the atomizer."

Normally, contact trigger means "contact with an aura."  So how important is the use of the word "substance" here? Does it actually mean that an LOS contact prep doesn't need to actually touch an aura to activate?  Meaning that if it's sprayed on a wall, the effect will then jump to whichever aura is closest to the spot on the wall?

Actually, since it repeatedly uses the word "compounds," does it even work on regular preps at all by RAW?
