So I have always been a fan of “weird science alchemy” in a RPG. SO here is a page of rough notes in case it becomes needed. No Healing stuff here though moved that purely to the Herbalists.

Generally you’ll need to justify having this skill to attempt it. Any Sorcerer is OK, probably most Elf mages as well.  Thieves can roll to make Poisons/Antidotes & Incendiaries without needing to justify why they have the knowledge.

Skys the limit peoples. Role play it I can allow it 🙂 If you actually rolled “Alchemist” on your Background that’s gotta be worth a +2 on success dice over and above any other adjustment I rule 🙂

Before the roll the would be alchemist needs to state what they  are attempting to make: It will be presumed they have access to the right tools and or ingredients before they even try! If they are improvising then a -1 to – 4 Penalty will apply. A really good lab or exotic materials will grant a similar level of BONUS to the roll (each) Basic materials can be obtained in any city or town, Assume that the character pays out the stated cost to attempt each roll in buying/making the components for the attempted brew. A roll greater than 14 is ignored unless the Alchemist spent DOUBLE the base cost on components first. Score of 20+ Can only be applied if Four times the base cost was risked before the dice was cast!

Add the characters Exp level as a bonus. Adjust some more to their luck modifier. Luck may be burned on the roll of course! (This might explain why in the wide world many alchemists may have a level of thief! – Snake oil sales man anybody?) I might be persuaded to allow INT modifiers as well in some cases. but not all: Alchemy is more about luck than precision its NOT Chemistry after all!

The list of types here is not the be all and end all. Its just what I could think of off the top of my head. Anybody with added ideas please feel free to comment and we’ll see if we can build it in 🙂

• Typically these will have a reverse effect after they are through = 2x the effect but perhaps on other attributes.
