Alchemical Scholar

You gain the Alchemical Crafting feat. If you would automatically gain that feat (from your background or the alchemist class, for example), you instead gain a different 1st-level Crafting skill feat. Add an additional common 1st-level alchemical formula to your formula book when you take this feat. Each time you gain a level beyond 1st, add one common alchemical formula of that level to your formula book.
