Educated swindler/Plague Doctor

Your expertise has led you to study the field of medicine, granting you the ability to create potent remedies and toxins. 

“The evil in the world comes almost always from ignorance, and goodwill can cause as much damage as ill-will if it is not enlightened. People are more often good than bad, though in fact that is not the question. But they are more or less ignorant and this is what one calls vice or virtue, the most appalling vice being the ignorance that thinks it knows everything and which consequently authorizes itself to kill. The murderer's soul is blind, and there is no true goodness or fine love without the greatest possible degree of clear-sightedness.”
― Albert Camus, The Plague

Humoral insight

Your expertise has led you to study the field of medicine, granting you the ability to create potent remedies and toxins. To make these concoctions you use reactant points. You have an amount of reactant points equal to your level in the rogue class. You regain all of your reactant points after a long rest.

You can create potions at the end of a long rest or by spending 1 hour. A potion requires a type and effect. The type chart details the types available. A potion may only have one type. The effect chart details the effects available. A potion can have any number of effects. Potions lasts until next long rest (can't stockpile).

When you choose this archetype at 3rd level, you gain proficiency in the use of the Poisoner's kit and proficiency in the use of Alchemist's supplies.

In addition, you gain advantage on checks to identify poison and potions.

Potions table

Type chart	Cost	Min level
Ingested	0	3
Injury	2	3
Contact	3	9
Inhale	5	13

Injury

Can be applied to weapons. The poison lasts for 1 minute after being applied. The poison can be applied to one weapon or two if they have the light property. 5 pieces of ammunition can be coated in the poison. You can use your bonus action to coat your weapon(s).

Inhale

A gas that targets any creature within a 10 feet radius. This radius can be increased by spending reactant points. For every 2 reactant points spent this way, its radius is increased by 5 feet. Inhale only works with negative effects. Inhale cant be used for coating of weapons/arrows or bolts.

Effectiveness

Your poison save DC is 8 + your proficiency modifier. Creatures targeted by potions with negative effects make a constitution saving throw against your poison save DC. If they fail they are affected by all negative effects of the potion until the end of their duration, or an effect such as lesser restoration removes it. You can increase this save for a particular poison by spending reactant points. For each point spent this way, increase the save of the poison by +1.
