Characters with the Alchemy Skill can use and create Alchemical substances such as poisons, gas globes and more. Alchemy is a Production Skill (see the “Production Skills” section for details). To produce an Alchemical substance, you must have a formula book and the specific formula for that substance. Formulas must be in a book much like the spell books used by spellcasters and must abide by the same rules.
This book is an IG item and can be stolen. If you lose your book, you lose all the formulas within. You will have to find someone with the formulas and recopy them into your book again before you can create any new Alchemical substances. Note that unlike spell books, you do not have to pay game money to use a special ink to write the formulas into the book, although the person from whom you get the formulas may demand payment IG.
When you learn a formula, you learn all the ways to make it such as a gas, an elixir, or a coating. You choose what form the formula will take at logistics.
You may not “reverse engineer” an Alchemical substance to learn the formula.
Even though they are available IG, some Alchemical substances exist which can never be made by characters. For instance, you should never find a formula book containing Enslavement or Euphoria. It is possible, however, to find unusual gas globes or elixirs which although they cannot be made by characters can still be used.
