The Definitive Alchemist

(v1.05 now available!  Change log below description)

A 5th edition conversion of a much-beloved class, complete with six fields of study to choose from and over a dozen ways to combine them to make the alchemist that is just right for you.  Whether you want to brew potions, transform your body, or just blow things up, this class contains options for any flavour of alchemist.

Any alchemist can throw a bomb, but Destruction specialists can turn this simple science into a terrifying art form, while those favouring the field of Mutagenics perform art and science with their own bodies, changing themselves to adapt to almost any situation.  Specialise in plagues and poisons with the field of Blight-making; cure maladies, protect your allies and restore health and life as a Blight-breaker; pervert life instead and blur the barrier between life and undeath with the field of Reanimation, or simply build your own friends where fragile biological ones fail you with the field of Mechanism.

With the ability to pursue any two of these disciplines, each alchemist you make can be unique and spectacular in their own personal way, offering a staggering opportunity for fresh and different characters.

Supplementing the class itself, this document also provides extended tables for the crafting of alchemical items, poisons and restoratives, along with suggestions and guidelines for creating more, and can serve as a useful list for alchemists, non-alchemists and DMs alike.

v1.05 Change Log

- Alchemy: Formula Use: Clarified that alchemist formulae still count as spells for most purposes, and as such are still susceptible to antimagic fields, dispel magic and counterspelling, etc.

- Field of Mechanism: Combat Prowess: Stalwart Defender no longer halves damage taken; being able to wear the attack for an ally was deemed strong enough on its own.

- Field of Mechanism: More Machines: Your secondary construct does not gain additional Ability Score increases like your primary construct. It is now limited to a maximum of two construct upgrades; one at 14th level when you first complete it, and a second at 19th level.

- Field of Reanimation: Deathwatch: As a 1st level ability, this can still foil feign death, as that is very much its speciality area, but it can't overcome other spells or more powerful deception magic or items.

- Discovery: Bone Puppet Bombs: Bone Puppet Bombs cannot be used to raise undead or constructs, and the animation lasts for 1 minute.

- Discovery: Chromatic Bombs: With regret, removed Radiant and Necrotic as damage type options from this discovery.

- Discovery: Healing Bombs: Added an extra qualifier, requiring that the formulae used must not have any effect that deals damage; no more blast applications of Armour of Agathys, sorry.

- Discovery: Master of Creation: Clarified, you only gain the free formula once; exchanging and re-taking the discovery will not grant you a double-dip.

- Construct Upgrades: Adamantine Body: The perks of this body upgrade warranted an additional penalty. The sheer weight of an adamantine body now also reduces your construct's speed by 5 feet.

- Construct Upgrades: Extended Vaporiser: clarified that the vaporiser works specifically with your alchemical bomb cantrip, and not any bomb you happen to make.

- Construct Upgrades: Flyby Enhancement: Modified so that the construct does not provoke an opportunity attack only if it enters and leaves the hostile creature's range on the same turn while flying. Elsewise, while flying, opportunity attacks it provokes are made at disadvantage.

- Construct Upgrades: Skill Improvement: integrating a tool when your construct gains proficiency or expertise now requires you to actually have a set of the tools to hand to integrate. Removed redundant note regarding expertise not stacking.

- Spells: Alchemical Bomb: For all it can do, a d8 was a bit too punchy. The cantrip damage die has been reduced by one step, from a d8 to a d6. The Destructive Bombs discovery has also had its bonus damage reduced from a d8 to a d6, in line with this change.

This class is quite complex, but don't let that put you off it. The author has worked very hard to try and create a version of the pathfinder alchemist for 5e DnD that actually feels like the class it was based on. Normally when people do adaptations [...]

It does a good job of capturing the feel of the pathfinder style of alchemists while staying in the design and style of 5e D&D. [...]

Rules Edition(s)
Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
