Poisoner

Master of Toxins. For as long as fantasy has been written, one of the main archetypes of the rogue has been that of the poisoner. Assassins wield poison coated blades, snipers lace bolt tips with viper venom, and spies pour small vials into goblets. This subclass aims to let you live out that archetype.

Building Tolerance

Your work with toxins has begun to build up your own bodies tolerance against them. You gain resistance to poison damage and proficiency in both Constitution Saving Throws and Poisoner's kits.

Toxic Coatings

Through your study of poisons, venoms, and toxins, you have concocted a special coating that you can coat your weapons with. When you take this subclass at 3rd level, whenever you use your sneak attack class feature you can change the damage of your sneak attack dice to Poison damage. When you do this, if you hit with the attack the target must make a Constitution saving throw with a DC of 10 plus the number of sneak attack dice you have or become Poisoned for 1 minute, repeating their saving throw at the end of each of their turns.

Pick Your Poison

Your mastery over toxic substances has allowed you to further develop your Toxic Coating. You now have access to the following additional poisons, and you can use each new poison once before taking a short rest to restock. You may only apply these poisons on an attack that can use Sneak attack, you must declare that you are using this feature before you make the attack, and you must chose to use your Toxic Coating feature when you do. Additionally, the poison damage dealt by your Toxic Coating feature ignores resistance to poison damage.
