Alchemist Class Features
You gain these abilities as an alchemist. Abilities gained at higher levels list the levels at which you gain them next to the features’ names.
Ancestry and Background
In addition to the abilities provided by your class at 1st level, you have the benefits of your selected ancestry and background.
At 1st level, you gain a number of proficiencies that represent your basic training. These proficiencies are noted at the start of this class.
You understand the complex interactions of natural and unnatural substances and can concoct alchemical items to meet your needs. You can do this using normal reagents and the Craft activity, or you can use special infused reagents that allow you to craft temporary items quickly and at no cost. Over time, you can create more and more alchemical items for free, and since each of them becomes more and more powerful, you advance in power dramatically, leaving behind those who don’t understand your strange science. You gain the Alchemical Crafting feat, even if you don’t meet that feat’s prerequisites, and you gain the four common 1st-level alchemical formulas granted by that feat. You can use this feat to create alchemical items as long as you have the items’ formulas in your formula book.
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 equal to your level + your Intelligence modifier. You can use these reagents for either advanced alchemy or Quick Alchemy, described below. Together, these infused reagents have light Bulk. As soon as you make your next daily preparations, your infused reagents from the previous day’s preparations are instantly destroyed, and nonpermanent effects of your previous day’s infused items immediately end. While infused reagents are physical objects, they can’t be duplicated, preserved, or created in any way other than your daily preparations. Any such artificial reagents lack the infusion and are useless for advanced alchemy or Quick Alchemy.
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, and you ignore both the number of days typically required to create the items and any alchemical reagent requirements. Your advanced alchemy level is equal to your level. For each batch of infused reagents you spend, choose an alchemical item of your advanced alchemy level or lower that’s in your formula book, and make a batch of two of that item. These items have the infused trait and remain potent for 24 hours or until your next daily preparations, whichever comes first.
If you need a specific alchemical item on the fly, you can use your infused reagents to quickly create it with the Quick Alchemy action. You swiftly mix up a short-lived alchemical item to use at a moment’s notice. You create a single alchemical item of your advanced alchemy level or lower that’s in your formula book without having to spend the normal monetary cost in alchemical reagents or needing to attempt a Crafting check. This item has the infused trait, but it remains potent only until the start of your next turn.

An alchemist keeps meticulous records of the formulas for every item they can create. You start with a standard formula book worth 10 sp or less for free. The formula book contains the formulas for two common 1st-level alchemical items of your choice, in addition to those you gained from Alchemical Crafting and your research field. Each time you gain a level, you can add the formulas for two common alchemical items to your formula book. These new formulas can be for any level of item you can create. You learn these formulas automatically, but it’s also possible to find or buy additional formulas in settlements or from other alchemists, or to invent them with the Inventor feat.
Your inquiries into the alchemical nature of the universe have led you to focus on a particular field of research. You might have a degree from an scientific institute, correspond with other researchers in your field, or work as a genius loner. Choose a field of research. The research fields presented in this book are as follows.
You specialize in explosions and other violent alchemical reactions. You start with the formulas for two 1st-level alchemical bombs in your formula book, in addition to your other formulas. When throwing an alchemical bomb with the splash trait, you can deal splash damage to only your primary target instead of the usual splash area.
You concentrate on Healing others with alchemy. You start with the formulas for two of the following in your formula book, in addition to your other formulas: lesser antidote, lesser antiplague, or lesser elixir of life. As long as your proficiency rank in Medicine is trained or better, you can attempt a Crafting check instead of a Medicine check for any of Medicine’s untrained and trained uses.
You focus on bizarre mutagenic transformations that sacrifice one aspect of a creature’s physical or psychological being in order to strengthen another. You start with the formulas for two 1st-level mutagens in your formula book, in addition to your other formulas. You can gain the benefit of any mutagen, even if it wasn’t specifically brewed for you. Whenever your proficiency rank for simple weapons increases, your proficiency rank for unarmed attacks increases to the same rank unless it’s already better.
At 1st level and every even-numbered level thereafter, you gain an alchemist class feat.
At 2nd level and every 2 levels thereafter, you gain a skill feat. Skill feats have the skill trait. You must be trained or better in the corresponding skill to select a skill feat.
At 3rd level and every 4 levels thereafter, you gain a general feat.
At 3rd level and every 2 levels thereafter, you gain a skill increase. You can use this increase either to increase your proficiency rank to trained in one skill you’re untrained in, or to increase your proficiency rank in one skill in which you’re already trained to expert. At 7th level, you can use skill increases to increase your proficiency rank to master in a skill in which you’re already an expert, and at 15th level, you can use them to increase your proficiency rank to legendary in a skill in which you’re already a master.
At 5th level and every 5 levels thereafter, you boost four different ability scores. You can use these ability boosts to increase your ability scores above 18. Boosting an ability score increases it by 1 if it’s already 18 or above, or by 2 if it starts out below 18.
In addition to the ancestry feat you started with, you gain an ancestry feat at 5th level and every 4 levels thereafter. The list of ancestry feats available to you can be found in your ancestry’s entry.

These items do not have to be the same.

Chirurgeon: When you use Quick Alchemy to create any type of elixir of life, the creature drinking the elixir gains the maximum Hit Points possible for that elixir, instead of rolling to determine the number of Hit Points regained.
Mutagenist: If you imbibe another mutagen while you are under the effects of a mutagen that you created, you can gain the benefits and the drawbacks of both mutagens at once, despite the fact that they both have the polymorph trait and would not normally function together. If you come under the effects of any further mutagens while benefiting from two mutagens, you lose the benefit of one of the former mutagens of your choice, while retaining the drawbacks of all the mutagens. If you are under the effects of two mutagens and you come under the effect of a non-mutagen polymorph effect, you lose the benefits of the mutagens while retaining the drawbacks of both.
