An Alchemist turns careful observation and portable reagents into battlefield support. Rather than relying on conventional spellcasting, an Alchemist brews short-lived draughts that bolster allies, hinder foes, and turn preparation into a tactical advantage. Their craft rewards choosing the right formula, timing its use, and staying close enough to help.
A measured hand, a useful vial, and one more chance to turn the tide.

Intelligence
ConstitutionYou gain proficiency with alchemist’s supplies and herbalism kits. You can use Intelligence instead of Dexterity for Sleight of Hand checks made to handle or administer a potion, and you learn the Brew Potions feature.
You learn two options from the Potion Formulae list. Your formula save DC equals 8 + your Proficiency Bonus + your Intelligence modifier, and your formula attack modifier equals your Proficiency Bonus + your Intelligence modifier.
You have reagent points equal to your Proficiency Bonus + your Intelligence modifier (minimum 2). You regain all spent points when you finish a Long Rest; you also recover 1 spent point when you finish a Short Rest.
With suitable materials and alchemist’s supplies, you can spend 1 hour to brew three doses, rolling randomly on Potion Formulae for each, or 30 minutes to brew one dose of a formula you know. Each dose costs 1 reagent point, lasts until your next Long Rest, and can be administered to a willing creature as a Bonus Action or thrown at a point you can see within 30 feet as an action. A dose’s effect and save DC are determined when it is used; an unwilling creature can resist a dose by succeeding on its listed saving throw. You can have no more than your Proficiency Bonus doses at once.
When you or a creature you can see within 30 feet takes damage, you can use your Reaction and expend 1 reagent point to reduce that damage by 1d8 + your Intelligence modifier. The reduction increases to 2d8 at level 10 and 3d8 at level 18.
Choose Chemist, Alchemancer, or Blood Alchemist. Your subclass grants features at levels 3, 6, 10, and 14.

Ability Score Improvement
When a creature you can see within 30 feet fails a saving throw against one of your doses, you can use your Reaction to let it reroll the save. You can use this feature a number of times equal to your Intelligence modifier (minimum once), regaining all uses on a Long Rest.
Your Alchemical Discipline grants a feature.
Your reagent reserve increases by 2. Once per Long Rest, you can brew one dose you know without spending a reagent point.

MulticlassingPrerequisite: Intelligence 13. When you multiclass into Alchemist, you gain proficiency with alchemist’s supplies. Your Alchemist levels determine your Alchemist features; reagent points and prepared-dose limits use your Alchemist level and Proficiency Bonus as specified by those features.
When brewing randomly, roll a d8 to select a formula. Each dose is one-use; an enemy targeted by a dose makes the listed saving throw against your formula save DC.

An Alchemist turns careful observation and portable reagents into battlefield support.
Rather than relying on conventional spellcasting, an Alchemist brews short-lived draughts that bolster allies, hinder foes, and turn preparation into a tactical advantage. Their craft rewards choosing the right formula, timing its use, and staying close enough to help.
Prepare doses before trouble, then spend combat turns choosing whether to help an ally, debilitate an enemy, or protect someone with Emergency Antidote.
Your strongest turns come from anticipating who will need what; you are a support specialist, not a front-line damage dealer. Check with your DM that your character can acquire suitable brewing materials during the campaign.
Most Alchemists apprentice in an apothecary, healer’s workshop, research college, or traveling company.
Initiation is practical: identify safe ingredients, prepare a reliable remedy, and demonstrate that the student can handle volatile substances without endangering others.
People welcome Alchemists when sickness or danger strikes, but may distrust unfamiliar vials and strange smells.
In towns with strict guild rules they are expected to prove their work is safe; in the wilderness they are often treated as indispensable problem-solvers.
