Ok. I was thinking of bringing back a concept I had a while back. The Alchemist can imbue water with special properties like from acidity or "freezes on contact" to accelerated healing, but the process takes too long to be usable on the fly, so they bottle up useful brews and use them like potions or grenades. Also they own a coffee shop.

Otherwise I can think of a less abusable power.

It's a rather unique idea, I mean as long as your aware of how it can be abused and find a way to limit it so that it's not abused I'd be cool with it. Keep the ingredients rare for more potent brews etc. 

Love the coffee shop angle.
