Brewmaster

A fighter who practices in the art of Brewmastery sounds like they could be easily mistaken for a bartender, but in truth the practice is far from leisurely. Brewmasters are warriors focused on tipping the scales of battle in their favor through chemical warfare. Rigorous tests made through consuming numerous concoctions have given them an unnatural hardiness, capable of empowering themselves with potent elixirs and serums, and bolstering their weapons with alchemical toxins and arcane mixtures. The Brewmaster is a fighter who focuses on preparation before each battle for maximum efficiency, closing the gaps in their team’s defenses and opening weak points on their enemies. A versatile combatant that works at any range and is able to support their allies in multiple ways.

Brewmaster's Proficiency

At 3rd level your experience with gathering medicinal herbs and testing variants of chemicals have given you proficiency in your choice of two different tools from either Alchemist’s Supplies, Herbalism Kits, Brewer’s Supplies, or Poisoner’s Kits, and you have resistance to poison damage and advantage against being poisoned.

Brewed Concoctions

At the start of your 3rd level, you’ve learned to create powerful benefits in the form of tinctures, salves, vapors, or oils that can be used on your weapons, your allies, or yourself.

You choose two concoctions from the ones featured, you gain your choice of one additional type of concoction at 5th, 9th, 13th, and 17th level. 

During a long rest you can choose the type of concoctions you wish to prepare for the day based on the ones featured below, up to a number equal to your proficiency bonus, these can be multiples of the same concoction and you can choose a new batch of concoctions after each long rest. These concoctions have a brief shelf life, causing them to expire after one day, and as part of a short rest you can replenish half of your stock rounded up of the brewed concoctions you prepared.

As a bonus action you can either consume the concoction or coat your weapon with it, each application provides different effects. You can also pass it to an allied creature that you can see within 30 feet of you which they can then choose to use as a reaction on your turn.

You use 8 + Your Proficiency + Your Constitution Modifier when determining saving throws made against your concoctions.

Toxic Overdose

Before a concoctions' duration ends, if a creature consumes more than one concoction at a time, or a creature is hit by another weapon coated in your concoctions while the other is still active, they must make a Constitution saving throw against your concoctions' DC which you have advantage against. On a success, a hostile creature takes no damage and the effects of any concoctions end. On a success after consuming another concoction, all active concoctions durations are reset to an hour. If this saving throw is failed, they take 2d12 poison damage, they gain the Poisoned condition for one minute, and all other effects are neutralized. At the end of each turn the creature can make a saving throw against this effect. On a success, the effect ends. While consuming a concoction, the saving throw DC against this effect is increased by 5 for each concoction still active.

Potent Potions

When using a bonus action to consume one of your concoctions, that creature gains 1d12 + your Constitution Modifier in temporary hit points that lasts for the concoctions' duration unless another concoction is already active. When you use a concoction on a weapon it gains the ability to deal critical hits on a 19 or 20 for the concoctions' entire duration.

At 10th level, you are able to destabilize your concoctions with a mutagenic catalyst in order to create powerful new effects with certain risks.

During this time any creature benefiting from this effect is considered vulnerable to poison damage and the poisoned condition.

You may also use this feature as an action to spend two of your concoctions to toss in a location of your choosing within 30 feet of you. Creatures within a 15 foot radius of where this compound lands must make a Dexterity saving throw. On a failed save it causes two of the following effects based on which concoctions were thrown:

Magical Mixtures

Starting at 15th level, your skills as a brewmaster have unearthed new uses from the brews you concoct by mixing them into powerful magical effects. As an action you can cast spells crafted from the type and number of concoctions you mix together, the combinations of concoctions you choose to create will determine the outcome of the spell based on the DM’s discretion. After which, you can memorize that mixture for whenever you choose to cast that spell again. Each concoction used is equal to a single spell slot, so mixing 3 of your concoctions would allow you to cast a spell up to the 3rd level. Here are some examples of mixes you might try below:

Emboldening Serum + Quickening Elixir + Quickening Elixir = Thunder Step

Beautifying Salve + Sharpening Oil + Invigorating Vapors = Tongues

Impeding Elixir + Dizzying Vapors + Weakening Tonic = Slow

Your Constitution is used for determining your spellcasting abilities.

Master of Concoctions

At 18th level you've unlocked your concoctions’ full potential, allowing you to defy death itself. If you have no more concoctions prepared before rolling initiative, you can choose to go last and start the round with one Brewed Concoction. The damage you deal from your concoctions is doubled and at the start of every turn you regain a number of hit points equal to your Constitution modifier for each concoction active. Lastly, when a concoction is consumed by a creature, while the concoctions' effects are active, if that creature’s hit points were to drop to 0, it instead only drops to 1 and the concoctions' effects end.
