Preparing and Using Formula

The Alchemist table shows how many formula slots you have to cast your spells of 1st level and higher. To cast one of those spells, you must expend a slot of the spell’s level or higher. You regain all expended formula slots when you finish a long rest.

You prepare the list of alchemist formula spells that are available for you to cast. To do so, choose a number of Formula from your Formula book equal to your Intelligence Modifier plus half your Alchemist level (minimum of one spell). The formula must be of a level for which you have formula slots.

You can change your list of prepared formula when you finish a long rest. Preparing a new list of formula requires time spent studying your formula book, gathering reagents, and brewing alchemical mixtures.

​

Formula Ability

Intelligence is your spellcasting ability for your alchemical formulas, since you learn your formula through dedicated study and experimentation. You use your Intelligence whenever a formula refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for an alchemist formula you use and when making an attack roll with one.

Spell save DC = 8 + your proficiency bonus +�your Intelligence modifier

Spell attack modifier = your proficiency bonus +�Your Intelligence modifier

​

Formula Focus

You can use alchemist supplies (found in chapter 5) as a spellcasting focus for your alchemist formula.

​

Learning Formulas of 1st Level and Higher

Each time you gain an alchemist level you can add one alchemical formula of your choice to your formula book. This formula must be of a level for which you have formula slots, as shown on the Alchemist table. On your adventures, you might find other formula that you can add to your formula book.

​

Alchemist

Whether secreted away in a smoky basement laboratory or gleefully experimenting in a well-respected school of magic, the alchemist is often regarded as being just as unstable, unpredictable, and dangerous as the concoctions he brews. While some creators of alchemical items content themselves with sedentary lives as merchants, providing alchemical fire and healing potions, the true alchemist answers a deeper calling. Rather than cast magic like a spellcaster, the alchemist captures his own magic potential within liquids and extracts he creates, infusing his chemicals with virulent power to grant him impressive skill with poisons, explosives, and all manner of self-transformative magic.

Your Formula Book

The formula that you add to your formula book as you gain levels reflect the scientific research you conduct on your own as well as intellectual breakthroughs you have had about the nature of the multiverse. You might find other formula during your adventures. You could discover a formula recorded on a scroll in an evil alchemist’s chest, for example, or in a dusty tome in an ancient library.

Copying a Formula into the Book. When you find an alchemical formula of 1st level or higher, you can add it to your formula book if it is of a level for which you have formula slots and if you can spare the time to decipher and copy it.

Copying a formula into your formula book involves reproducing the basic form of the formula, then deciphering the unique system of notation used by the alchemist who wrote it. You must practice the formula until you understand the reagents required, then transcribe it into your formula book using your own notation.

For each level of the formula, the process takes 2 hours and costs 50 gp. The cost represents material components you expend as you experiment with the formula to master it, as well as the fine inks you need to record it. Once you have spent this time and money, you can prepare the formula just like your other formulas.

If you are tutored by the alchemist who wrote the formula you are attempting to copy the process instead takes 1 hour and costs 25 gp.

Replacing the Book. You can copy a formula from your own formula book into another book--for example, if you want to make a backup copy of your spellbook. This is just like copying a new spell into your spellbook, but faster and easier, since you understand your own notation and already know how to prepare the formula. You need spend only 1 hour and 10 gp for each level of the copied formula.

If you lose your spellbook, you can use the same procedure to transcribe the formulas that you have prepared into a new formula book. Filling out the remainder of your formula book required you to find new formulas to do so, as normal. For this reason, many alchemists keep backup formula books in a safe place.

The Book’s Appearance. Your formula book is a unique compilation of formulas, with its own decorative flourishes and margin notes. It might be a plain, functional leather volume, a finely bound gilt-edged tome, or even a loose collection of notes scrounged together.

Wizard Spells. You may copy wizard spells on the alchemist list into your formula book and wizards may copy formula from alchemist books into their own. Doing so takes twice the time and gold investment however.
