alchemical investigator and poisoner archetype

[TiwazBlackhand]

Did a cursory search and didn't find a thread on this.

How do these interact? Do they interact?

I might be wrong, but it kind of looks like they don't?

Alchemical investigator doesn't get infused reagents, it gets versatile vitals, and it's quick tincture uses those.

So level 2 18 int Alchemical Sciences Investigator with Poisoner Archetype would get 4 Versatile Vitals usable only for Quick Tincture to make Elixers and Tools, and 2 Infused Reagents usable only for Advanced Alchemy to make lvl 1 poisons?

A level 10 20 int version with Expert Poisoner would get 5 Versatile Vials usable only for QT for Elixers and Tools, and 10 Infused Reagents usable only for Advanced Alchemy to make poisons up to lvl 7?

Does this scan correctly?

That is correct, they don't mix together but that doesn't mean it's actually a bad idea since you're getting two new daily resource pools instead of having to deal with double-dipping from the save VVs or QT pools.
