Poisoner (Homebrew Revision)

You can prepare and deliver deadly poisons, ranging from flesh melting acids and decay inducing liquids to the standard poisons, granting you the following benefits:

• When you make a damage roll that deals poison damage, it ignores resistance to poison damage. 
• You can apply poison to a weapon or piece of ammunition as a bonus action, instead of an action.
• You gain proficiency with the Poisoner's Kit if you don't already have it. With one hour of work using a poisoner's kit and expending 50 gp worth of materials, you can create a number of doses equal to your proficiency bonus. The type of dose is chosen when you make the doses, and can't be changed by any means. Once applied to a weapon or piece of ammunition, the poison, acid or liquid retains it's 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 equal to 8 + your proficiency bonus + your intelligence modifier. If the target fails the saving throw, they take 2d8 acid, poison or necrotic damage, depending on what dose was made, and suffer the condition caused by the dose. If they succeed the saving throw, they take half the damage and do not suffer any conditions.
  • Acid Dose: Upon failing the saving throw, the target suffers an acidic burn, taking 1d4 acid damage at the start of their turns. The target or someone within 5ft of them can take an action to wipe the acid off of them, ending this effect.
  • Necrotic Dose: Upon failing the saving throw, the target's body begins deteriorating. The target has disadvantage on ability checks, attack rolls and saving throws made using strength. At the end of their turns, they can roll a Constitution saving throw against your DC, ending this effect on a success.
  • Poison Dose: Upon failing the saving throw, the target becomes poisoned until the end of your next turn.
