Poisoner

You use various chemical and alchemical compounds to take out dangerous targets. You have recipes for each situation, and spend all of your free time experimenting, sometimes even on yourself.

Well prepared

At third level, you learn the art of crafting and using poisons.

Types of poisons

Poisons come in the following four types:

Contact: Contact poison can be smeared on an object and remains potent until it is touched or washed off. A creature that touches contact poison with exposed skin suffers its effects.
Ingested: A creature must swallow an entire dose of ingested poison to suffer its effects. The dose can be delivered in food or a liquid.
Inhaled: These poisons are powders or gases that take effect when inhaled. Blowing the powder or releasing the gas subjects creatures in a 5-foot cube to its effect. The resulting cloud dissipates immediately afterward. Holding one’s breath is ineffective against inhaled poisons, as they affect nasal membranes, tear ducts, and other parts of the body.
Injury: Injury poison can be applied to Weapons, Ammunition, trap Components, and other Objects that deal piercing or slashing damage.

Recipes

You learn three poison recipes. You learn one new recipe at 6th, 9th, 12th, and 15th, level. Additionally, whenever you gain a level, you can replace a recipe you know with another from this table.

Crafting poisons

You gain proficiency with the Poisoner's Kit. When you attempt to create a poison from the table below, you must spend the amount of time and components indicated in the recipe, and then must make an ability check with the Poisoner's Kit, using Intelligence. If you beat the recipe's crafting DC, the poison is added to your equipment.

If you attempt to make a poison you know the recipe of, you double your proficiency bonus for this ability check, and the crafting time and components are halved.

Poisonous Coating

You can coat weapons and pieces of ammunition with poisons if they have the Injury type. Doing so is a very delicate affair. It takes you ten minutes to coat one weapon, or up to twenty pieces of ammunition, and the poison is consumed in the process. The poison remains active for one hour, and then it dries and disappears. During this time, if you use the coated weapon or ammunition to deal slashing or piercing damage to a creature, that creature becomes subject to the effects described in the table above.

When you coat an item that is already coated in poison, the previous coating is removed to make space for the new coating. A single piece of equipment can only have one poisonous coating at a time.

Advanced Chemistry

At 9th level, whenever you attempt to make a poison you know the recipe of, you can spend additional components to alter the poison's effects. When you do, you are encouraged to come up with a unique name for your creation:

Name	Description	Additional Components
Invisible	The poison can also be delivered via ingestion	A vial of a werecreature's saliva
Venomous	The poison can also be delivered via injury	A vial of the blood of the creature this poison is supposed to target
Sporous	The poison can also be delivered via inhalation	100 GP worth of alchemical reactants
Thin	The poison can also be delivered via contact	A fey creature's lips
Potent	The save DC, if there is one, becomes 8 + your proficiency bonus + your INT modifier	Five eyes, all from the same creature
Diluted	You make twice as much poison	A flask of unholy water, cursed by the worshipper of an evil god
Enduring	If the victim fails the poison's saving throw, they stay poisoned for one minute after the poison's effects end	A tooth of someone who has died of old age
Reflux	If the victim fails the poison's saving throw, they have to make that saving throw again next turn or suffer 2d12 poison damage	A troll's heart
Long-lasting	If the poison's effect has a duration, that duration is doubled	Five living bees

Potent Alchemy

And 13th level, you include magical enchantments in your recipes, making them effective against a wider range of enemies.

If a creature is resistant to poison damage, poisons you make ignore that resistance. If that creature is immune to poison damage, poisons you make ignore this immunity, and deal half damage instead. If a creature is immune to the poisoned condition, poisons you make ignore this immunity, and the creature makes any saving throws against them with advantage instead.

Additionally, when you use a sneak attack with a weapon or a piece of ammunition coated in a poison you've made, the victim makes any saving throw against your poison with disadvantage. If they would have made that saving throw with advantage, they make a straight roll instead.

Combat Coating

At 17th level, you have spent so much time crafting and using poisons that you have naturally gotten a lot faster at it. As a bonus action, you can apply a new poisonous coating on a weapon you're wielding or on a piece of ammunition you're holding. However, applying the poisonous coating this quickly can be wasteful: the poison evaporates after one minute, instead of one hour.
