The Pathfinder 2 alchemist gets the Advanced Alchemy feature, which lets them spend their daily Infused Reagents resource to create alchemical items. The class description suggests that alchemist's tools are involved with this process. However, neither the Infused Reagents feature nor the Advanced Alchemy feature mention that alchemist's tools are required.
You infuse reagents with your own alchemical essence, allowing you to create alchemical items at no cost. Each day during your daily preparations, you gain a number of batches of infused reagents...
During your daily preparations, after producing new infused reagents, you can spend batches of those infused reagents to create infused alchemical items. You don’t need to attempt a Crafting check to do this...
These features are different than the Craft downtime activity, which requires tools.
Searching through the Core Rulebook, the only mentions of alchemist's tools are:
- pg 72: Quick Alchemy, a different alchemist feature that consumes infused reagents
- pg 81: Improbable Elixirs, an 18th level alchemist feat
- pg 245 & 480: the Identify Alchemy action (no reference to the alchemist class)
- pg 287-289: Alchemist's Tools listing in the "Gear" section (no reference to the alchemist class)
- pg 445: The definition of "Item bonus" uses alchemist's tools as an example.
Does an alchemist (or a non-alchemist with the alchemist archetype) actually need alchemist's tools to use Infused Reagents or Advanced Alchemy? Or can they make their daily preparations via Advanced Alchemy without using alchemist's tools?
