Investigator can choose Alchemical Sciences as their methodology at level 1 and start learning elixir or tool formulas, 1 common alchemical elixir or tool per level. At level 4 they can choose Alchemical Discoveries class which increases the amount to 2 instead.
Do I retroactively add the additional formulas for common alchemical elixirs or tools from level 1 through 3 to my formula book?
