You specialize in developing poisons, granting you proficiency with poisoner’s kits and the following benefits:

• When you create a poison, you can specify a creature type that poison is specifically made for. That poison ignores resistance and immunity to poison damage for that creature.

• You can apply poison to a weapon or piece of ammunition as a bonus action, instead of an action.

• During a long rest, you can perform 1 hour of work using a poisoner’s kit to create a number of doses of potent poison equal to your proficiency bonus, which last until you apply them to a weapon or finish your next long rest. Once applied to a weapon or piece of ammunition, the poison retains its potency for 1 minute or until you hit with the weapon or ammunition. When a creature takes damage from the coated weapon or ammunition, that creature must succeed on a Constitution saving throw (DC equal to 8 + twice your proficiency bonus) or take 1d8 poison damage and become poisoned until the end of your next turn. On success, they take half as much damage and aren’t poisoned.

When you use this feature to create poison, you can expend 15 gp per dose of poison to create a more deadly poison. When you do so, creatures that fail their Constitution saving throw against it take an extra 1d8 poison damage.
