I already have played with the alchemist, and it´s a interesting class, with some versality and good abilities, but, the problem i figured about the extracts class feature is that the number of extracts that it´s known is like the sorcerer number of spell mechanic, but for alchemy it isn't the same, doesn't work well. The alchemist has notes, scrolls with secret studies, schematics, and others things, that make more similar to the wizard and his grimory. Will be more adequated if it has the same mechanic: some 'alchemy book', were the alchemist inscribe news formulaes learned.
