You’re trained in
Crafting and gain the
Alchemical Crafting skill feat. You start with a standard
formula book, which contains the
formulas for two common 1st-level alchemical items of your choice (these must be
elixirs or
tools), in addition to the formulas gained from Alchemical Crafting. Each time you gain a level, you learn the formula for one common alchemical elixir or alchemical tool of any level of item you can create.
During your daily preparations, you can create a number of versatile vials equal to your Intelligence modifier. Statistics for versatile vials appear in the
alchemist class.
You gain the Quick Tincture action, which you can use to turn one of these vials into an elixir or alchemical tool for which you know the formula. If you have the ability to create versatile vials from more than one source (such as the
alchemist multiclass archetype), you can use any of your versatile vials for any ability you have that requires them.

infused trait, but it remains potent only until the end of the current turn.
