Multiclassing Alchemist

Alchemist

Whether their methods are explosive, transformative, or restorative, Alchemists transmute the world around them to their liking.

Explosive Reactions

One of the first things an Alchemist learns is which chemicals react explosively with one other. Ostensibly, this is to prevent deadly accidents, but adventuring Alchemists regularly apply this knowledge to create Bombs.

An alchemical bomb is a one-pound, apple-sized, spherical glass or clay flask filled with a reactive chemical. A smaller vial of thin glass containing a reagent is suspended in the liquid, and the whole thing is sealed with a cork or wax seal. When the inner vial breaks, usually on impact, the chemicals react with a violent explosion. With experimentation, an Alchemist can even infuse these explosions with elemental fire, lightning, or frost.

Serums and Tinctures

Experienced Alchemists learn to brew potions, alchemical concoctions that replicate magical effects. These range from the medicinal, such as Potions of Healing, to the transformative, such as Potions of Gaseous Form. Undisputed masters of potion-brewing, an adventuring Alchemist should have a surplus of potions to distribute among their allies.

Elemental Sciences

The source of alchemy’s power is the Elemental Planes. Therefore, it is no surprise that Alchemists strive to tap deeper into that power, researching and discovering new elemental compounds. The pinnacle of alchemy is the Philosopher’s Stone, which is rumored to grant its bearer supreme command of the elements. Few Alchemists have succeeded in creating a Philosopher’s Stone, and fewer still remain alive to divulge its secrets.

Class Features

Bombs (Level 1)

You can create volatile alchemical Bombs using the statistics shown in the Bomb sidebar.

Bomb Mastery. You have proficiency with Bombs and you can use the Bomb’s mastery property.

Priming Bombs. When you take the Attack action on your turn, you can prime a Bomb to increase its potency. Make one attack using a Bomb or use the Bomb’s Explode property; you can’t make any other attacks using this Attack action. Add your Intelligence modifier to the damage roll.

When you prime your Bomb and deal damage with it, its damage increases by 1d10 when you reach Alchemist levels 5 (2d10), 11 (3d10), and 17 (4d10).

Alchemist Save DC. Some of your Alchemist features require your target to make a saving throw. The save DC equals 8 plus your Intelligence modifier and Proficiency Bonus. You can use this saving throw for your Bombs instead of the DC specified in the Explode property.

How Many Bombs Do I Have?

As an Alchemist, you can use Alchemist’s Supplies to effectively make as many Bombs as you need for the adventuring day at no cost. If you prefer to track your inventory of Bombs manually, you can create a number of Bombs equal to 10 + twice your Alchemist level when you finish a Short or Long Rest. After 24 hours, an unused Bomb becomes inert.

Reagents (Level 1)

You have a collection of powerful reagents that you use to brew potions and empower your Bombs. You have 2 Reagents. You regain one expended Reagent when you finish a Short Rest, and you regain all expended Reagents when you finish a Long Rest. You gain additional Reagents when you reach certain Alchemist levels, as shown in the Reagents column of the Alchemist Features table.

Empowered Bomb. When you deal damage with a Bomb, you can expend a number of Reagents up to your Proficiency Bonus and add 1d10 to the Bomb’s damage roll for each expended Reagent.

Additionally, if you use the Bomb’s Explode property, you can increase the radius of the explosion by 5 feet. You can do so once for each expended Reagent. For example, if you expend 2 Reagents, you can choose for the Sphere to be a 5, 10 or 15-foot radius.

Potion Brewing (Level 1)

You can spend 10 minutes and expend any number of Reagents to brew potions, which can be done during a Short Rest. You can have a total number of potions at one time up to your Intelligence modifier (minimum of 1). These potions retain potency until you finish a Long Rest, after which they become inert.

When you brew potions, you can also distill potions you have already brewed, destroying them and recovering the Reagents expended to brew them, up to a maximum of the number of Reagents listed on the Alchemist Features table. You can expend these Reagents immediately to brew new potions.

Your potions don’t have unpredictable effects if a creature drinks one of your potions while still under the effects of another.

The number of Reagents and the Alchemist level required to brew a potion are given on the Potions table.

Bomb Formulae (Level 2)

Your research has uncovered new formulations for your Bombs that you can apply just before throwing them. Choose three Bomb Formulae from the “Bomb Formulae Options” section later in this class’s description.

Replacing and Gaining Formulae. When you reach certain Alchemist levels, you learn additional formulae of your choice, as shown in the Bomb Formulae column of the Alchemist Features table. Additionally, whenever you finish a Long Rest, you can replace one of your Bomb Formulae with another formula of your choice.

If another Alchemist feature gives you a Bomb Formula, it doesn’t count against your number of formulae.

Applying Bomb Formulae. Once per turn when you prime a Bomb, you can apply a Bomb Formula to it, granting it special effects and potentially changing its damage dice.

Reagent Synthesis (Level 2)

When you finish a Short Rest, you can regain an additional number of expended Reagents up to your Intelligence modifier (minimum of 1).

Once you use this feature, you can’t do so again until you finish a Long Rest.

Alchemist Subclass (Level 3)

You gain an Alchemist subclass of your choice. A subclass is a specialization that grants you features at certain Alchemist levels. For the rest of your career, you gain each of your subclass’s features that are of your Alchemist level or lower.

You gain the Ability Score Improvement feat or another feat of your choice for which you qualify.

Discoveries (Level 5)

In the course of your research, you have made a number of discoveries regarding the nature of alchemy. You gain one discovery of your choice from the “Discovery Options” section later in this class’s description

Whenever you gain an Alchemist level, you can replace one of your discoveries with another one for which you qualify. When you gain certain Alchemist levels, you gain more discoveries of your choice, as shown in the Discoveries column of the Alchemist Features table. You can’t pick the same discovery more than once.

Potion Brewing (Level 5)

Your Potion Brewing feature gains new potions for you to brew.

Subclass Feature (Level 6)

You gain a feature from your Alchemist Subclass.

You don’t benefit from this feature if you have the Incapacitated condition.

Ability Score Improvement (Level 8)

Epic Boon (Level 19)

You gain an Epic Boon feat or another feat of your choice for which you qualify.

Philosopher’s Stone (Level 20)

You gain the crowning achievement of alchemy: a Philosopher’s Stone, a dynamo of alchemical energy in a fist-sized, glowing jewel.

Constructing a New Philosopher’s Stone. If your Philosopher’s Stone is destroyed, you can construct a new one using Alchemist’s Supplies, materials worth 1,000+ GP, and 7 days of work. You can only have one Philosopher’s Stone at a time.

Philosopher’s Stone Benefits. As long as you possess the stone, you gain the following benefits:

Regenerating Reagents. When you roll Initiative, you regain expended Reagents until you have 6 if you have 5 or fewer.

Quick Brewing. You can brew potions as a Utilize action, instead of over the course of 10 minutes.

Longevity. For every ten years that pass, your body ages only one year.

Nuclear Bomb (Level 20)

You can utilize the most devastating Bomb Formula imaginable. By replacing your Bomb’s explosive contents with your Philosopher’s Stone, you can change it into a Nuclear Bomb. You must use the Bomb’s Explosive property. This Bomb deals 10d10 + 100 Force damage instead of its normal Fire damage, and its explosion is a Sphere with a radius of 1 mile. A creature within 60 feet of the center of the Sphere gains no benefit from Evasion or similar features.

This Bomb completely destroys your Philosopher’s Stone.
