Poison Brewmaster

3rd-level Poisoner feature

You have become an adept in creating poisonous substances. You gain proficiency in Poisoner's Kit and both the time and the cost of making poisons is halved.

Additionally, poisons you create, and other similar noxious substances used by this subclass features are specially potent, and the DC is calculated as:

Poisons DC: 8 + your proficiency modifier + your Intelligence modifier.

Lethal dose

3rd-level Poisoner feature

You also gain an additional way to use your Sneak Attack; you don’t need advantage on the attack roll to use your Sneak Attack against a creature if that creature is poisoned and you don't have disadvantage on the attack roll. All the other rules for Sneak Attack still apply to you.

Additionally, whenever you make a sneak attack against a creature, you can try to poison it. The creature makes a Constitution Saving throw against your Poisons DC. On a failure, the creature is poisoned for a number of rounds equal to your Intelligence modifier. A creature that has been poisoned is immune to this effect for 1 hour.

Noxious vials

9th-level Poisoner feature

You develop a special array of poisons, which are very volatile and only you can use them. During a long rest, you can produce two of these poisons, they will loose their potency after 24 hours or once used or applied. You can only apply one poison to each weapon.

• Lethal cloud: As an action, you can throw this vial at a point within 40ft. to cast vitrolic sphere at 4th level. The spell DC is equal to your Poisons spell DC.
• Corrosive oil: As a bonus action, you can apply this oil to one of your weapons. For the next minute, you attacks deal an additional 1d6 acid damage. Constructs and undead receive 2d6 acid damage instead.
• Crippling poison: As a bonus action, you can apply this toxin to one of your weapons. For the next minute, whenever you poison a creature with lethal dose, the creature's speed is reduced by 10ft., and the creature is blinded beyond a 5ft. radius.
• Sapping fog: As an action, you can throw this vial at a point within 40ft. Creatures within a 10ft. radius of that point must make a constitution saving throw against your Poisons DC. On a failure, the creature looses one resistance at random. If the creature is not resistant to anything, it instead will loose a proficiency in a saving throw at random.

Contaminated

13th-level Poisoner feature

After so many test on your own body, you have developed a very high resistance to poisons. You gain resistance to poison damage and immunity to the poisoned condition.

Toxic Overload

17th-level Poisoner feature

You have developed your toxic masterpiece, a lethal injection that overloads the subject with a lethal substance.

Whenever you deal damage with your Sneak Attack, you can inject an overdose in poison instead of applying Lethal Dose. During 1 minute, at the end of each of the target's turns, they must make a Constitution saving throw against your Poisons DC. On a success, they take half of 2d8 poison damage. On a failure, the target takes 2d8 poison damage and is under the effects of slow until the end of their next turn. If the target fails this saving throw twice in a row, it will instead be stunned until the end of their next turn.

Once you inject this poison, you can't do so again until you complete a long rest, unless you expend one of your noxious vials to do so.
