Guys, so ehm... was searching for wikies... Couldn't find anything clear.

I want to ask you all about alchemy mechanics, that I discovered for myself. If I understand it right, IT IS RETARTED.

So I need some ingridients to make a potion (grass X, moster part Y, some alcohol, bottle, etc).
And for the bomb - let's say saltpeter and some other shit "Z".

So when I make them the first time - it really looks like a propper alchemy - i need everthing in order to make 3 portions of a potion (ok, 3 portions, not one as b4), and i need something for 2 bombs.
OK.

BUT when i am running out of them - means I have an empty bottle (that used to contain 3 portions of a potion) and i have NO bombs left at all (although they are in inventory as 0\2) - all I need then is ONE BOTTLE OF RYE (alcohol) to replenish ALL potions AND bombs without any other ingridients.

What the hell? Oo Really?

so basically i have to make each potion only once? what is the point of gathering and harvesting then?

thx

That's correct, and there's not much point except to craft higher-level recipes.

This approach might make sense for potions and even oils, but it doesn't make sense for bombs. Still, I'm guessing CDPR chose this implementation so that bomb- or potion-reliant character builds wouldn't be stuck harvesting for 100 hours of gameplay. For better or worse, this does make the Green skill trees much more convenient.

Makes sense? No it doesn't)
When you are making a potion you need empty bottle, ingridients and alcohol. When you drink it, you drink all of it until the bottle is empty. Addin JUST alcohol makes it an ALCOHOL - not a potion.

Same with oils. U can't just rub greese on a blade. And what the hell is up with refreshind BOMBS - with alcohol? not even powder...

So I guess they made it all super casual?

And what do you mean by That's correct, and there's not much point except to craft higher-level recipes.

Thanks for trying, yes, i was looking for this, but still unrealistic - this way it wouldn't last forever and he would need another bottle for concentrate))

I don't know what are enhacned and superior formulae - do they work the same way? I mean do they require another set of plants and parts or dozens?

Should I collect now or just when I need?

Enhanced and Superior formulae are, in effect, leveled-up versions of the potion, oil, or bomb. You'll need the previous version to create them (It goes normal -> Enhanced -> Superior), and in the case of potions and bombs, each successive level adds another dose, a strengthening (and lengthening) of the effect; and the highest (Superior) level most often adds yet another effect that works well with the standard effect of the potion.
(Example: Swallow regenerates health, but its effect freezes for two seconds if you take a hit. Superior Swallow eliminates that freeze.)

Collect as you go, you can usually sell what you don't need.
