Study of Poisons

Study of Poisons is an Alchemist subclass.

Responsible for the more unsavory business conducted by alchemists, poisoners are often involved in shady business. They provide assassins and mercenaries with a myriad of toxic options to be used discreetly or in the heat of battle.

Toxic Waste

When you finish a long rest and brew potions, you can take all the toxic residue left behind by the alchemical processes and turn it into a small vial of deadly poison. It remains viable until the end of your next long rest and then goes inert. When you do so, choose one of the following options: 

Ingestion. You choose a poison that needs to be orally consumed to take effect. You can mix it with any of your potions, with another liquid, with food, and other means typical of this kind of poison. When a creature ingests the poison, they must succeed on a Constitution saving throw against your spell save DC. On a failure, the creature takes 4d8 poison damage and is poisoned for 8 hours, or half as much damage and no conditions on a success. 

Injection. You choose a poison that takes effect when coursing through the target's veins. The toxin is oily and thick, and can be used as a bonus action to coat a weapon or a single piece of ammunition and has enough for up to 4 applications. Once applied, it lasts until the end of your next long rest or until the weapon hits a creature. The next hit with the weapon deals an extra 1d8 poison damage and forces the target to succeed on a Constitution saving throw against your spell save DC or be poisoned for 1 minute. At the end of each of its turns, the target can make another Constitution saving throw, ending the poisoned condition on itself on a success.

Unsavory Knowledge

Also at 3rd level, you have earned knowledge on how to make a variety of concoctions that shady folks seek. You gain proficiency with the Poisoner's Kit, or expertise if you're already proficient with it.

Potent Poison

At 6th level, your Toxic Waste feature now uses d10's instead of d8's when rolling for damage. Additionally, any poison and potion that you make by any means, such as crafted items or potions made using your Potionmaking feature, now ignore resistance to poison damage, and you learn how to craft specific Poisons .

Master Poisoner

At 14th level, when you use your Toxic Waste feature, you can further process your poisons to change their effects:

Ingestion. You can replace the poisoned condition by the blinded or deafened conditions, or apply 2 levels of exhaustion instead.

Injection. You can replace the poisoned condition by the blinded, deafened, or stunned conditions, or deal an extra 2d10 poison damage instead.
