Hi there. I have a few questions regarding the alchemy craft skill. Here's the background: there's an alchemist player in my Sunday game that every creature that they defeat, he tries to extract from it something. He does this to "study them and create alchemical materials from it". Now he wants to prepare an antitoxin but i don't think he has the materials and any way to get them, since the pcs are trapped in a cavern.
My two questions are: are the alchemists capable of extracting poison from a snake? and create antitoxins from it? Or what are antitoxins, sunruds and other items created from?
What antitoxin's are made of are abstracted away by using an alchemists lab. For adventuring I suggest a portable alchemical lab. But it is assumed that anyone with Craft(alchemy) has the tools to create their alchemical items. The labs just give bonuses to the check.
I would ask for a Heal check to do extractions. DC15 or DC20 depending on how difficult to reach the item is. Also handling poison has a chance of poisoning the unwary (unless they have poison use skill). Once successfully extracted I would allow the use of the snake venom to give a bonus to either creating or the effectiveness of the antitoxin vs that specific venom (e.g. antitoxin that normally gives +5 bonus versus poison would give +6 versus that specific poison OR creating the antitoxin DC is reduced by 5).
So to answer your two questions:
Any one with a Heal check can extract poison from a snake. (GM allowing)
Using normal creation rules for alchemical items (Craft(alchemy)) e.g. DC25 to create a 50gp antitoxin. A GM can rule if they don't have the tools then they can't do it, or if they improvise the tools apply a penalty to the creation.
I would say: yes/yes to your both questions.
isn't it why the alchemist exist ? alchemists are master in poison anyway. And antitoxin needs a craft alchemy DC=25 to be done. You might give him a +2 bonus if he have a sample of the venom.
Until alchemist gets Swift Alchemy at 3rd level, the alchemist only gains a bonus to the actual Craft(alchemy) check (equal to his class level) and can't make potions any faster than any other character.
See Craft skill. Btw each check takes a week, but if they roll very well it could be done in less time. Also if the players are adventuring in this time it takes even longer (double the time spent actually crafting).
I would say: yes/yes to your both questions.isn't it why the alchemist exist ? alchemists are master in poison anyway. And antitoxin needs a craft alchemy DC=25 to be done. You might give him a +2 bonus if he have a sample of the venom.
Where does the materials to create the antitoxins come from? He just have them lay it around?

General alchemical materials are part of alchemist's kit (25gp, 5lb), portable lab, permanent lab and/or Artisan's Shop (the last one being a vanity available for 5PP in PFS play). If he has the kit, he doesn't actually _need_ any toxin from critters to make antitoxin--that's just a player adding flavor (good flavor imnsho; if it were a home game & I was gm, i'd discount crafting costs a bit). But regardless, even in PFS, just follow crafting rules for Craft (Alchemy) means he can make antitoxin (in PFS, it'd be at 1/3 cost). Time is the biggest factor in crafting, until he gets Swift Alchemy at 3rd level, and/or takes the Master Alchemist feat.
The game just sort of assumes that you acquire the materials...whatever they are. It's all abstracted, so your question doesn't really have a true "answer." It's similar to how the game abstracts material components. Have you ever glossed through what all these supposed "no significant cost" materials are? A lot are fairly exotic or odd things to find! And yet the game abstracts that, too. If you have the component pouch, you're just assumed to have (and re-fill..for free) whatever materials you my need. Hell, you can pick up a pouch from a dead enemy caster who had COMPLETELY different spells than you, and begin using it for yourself by RAW.
You're delving too deep into it. He has the skill, he takes the time, he makes the item.
