Poisons

Given their insidious and deadly nature, poisons are illegal in most societies but are a favorite tool among assassins, drow, and other evil creatures.

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. You might decide that a partial dose has a reduced effect, such as allowing advantage on the saving throw or dealing only half damage on a failed save. 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 and remains potent until delivered through a wound or washed off. A creature that takes piercing or slashing damage from an object coated with the poison is exposed to its effects.

Crafting and Harvesting Poison:

During downtime between adventures, a character can use the crafting rules in the Player's Handbook to create basic poison if the character has proficiency with a poisoner's kit. At your discretion, the character can craft other kinds of poison. Not all poison ingredients are available for purchase, and tracking down certain ingredients might form the basis of an entire adventure. T
Crafted poisons:

Name	Type	Brew DC	Description
Basic poison	Injury	10	You can use the poison in this vial to coat one slashing or piercing weapon or up to three pieces of ammunition. Applying the poison takes an action. A creature hit by the poisoned weapon or ammunition must make a DC 10 Constitution saving throw or take 1d6 poison damage. Once applied, the poison retains potency for 1 minute before drying.
Better poison	Injury	15	You can use the poison in this vial to coat one slashing or piercing weapon or up to three pieces of ammunition. Applying the poison takes an action. A creature hit by the poisoned weapon or ammunition must make a DC 15 Constitution saving throw or take 3d6 poison damage. Once applied, the poison retains potency for 1 minute before drying.

A creature hit by the poisoned weapon or ammunition must make a DC 10 Constitution saving throw or take 5d6 poison damage. Once applied, the poison retains potency for 1 minute before drying.
Toxic Variant	Inhaled or injested	20	An expert poison variant can be modified to act upon inhalation or injestion, instead of damage, other effects can be selected: Weakening - A creature affected by the poison becomes poisoned for 1d4 minutes if it fails a DC 15 constitution saving throw. Sleeping - A creature affected by the poison gains a point of exhaustion if it fails a DC 15 constitution saving throw.

A character can instead attempt to harvest poison from a poisonous creature, such as a snake, wyvern, or carrion crawler. The creature must be incapacitated or dead, and the harvesting requires 1d6 minutes followed by a DC 20 Intelligence (Nature) check. (Proficiency with the poisoner's kit applies to this check if the character doesn't have proficiency in Nature.) On a successful check, the character harvests enough poison for a single dose. On a failed check, the character is unable to extract any poison.
