I know you guys have heard this question thousands of times, I just know it.

A sorceror with a brew potion feat, could he create alchemist fire with DM help and something that would make sense to help create it? Perhaps a fire beetle belly?

How about an Acid Vial?

The list goes on.

Brew Potion has nothing to do with Alchemist's Fire creation. I don't remember how the creation of grenade-like weapons works, but I'm pretty sure it's already available IG (and if it isn't, there's probably a good reason).

It is (but figuring out the recipe is virtually impossible!).

lol, thanks for that!
