Poisoner

Your experience with the toxins and poisons of the world allows you to gain the following benefits:

• You gain proficiency in Poisoner's tools. 
• You have advantage on saving throws against mundane poison. 
• You can make an Investigation check with advantage to attempt to detect poison in food, drink or on a weapon. 
• You can take disadvantage on a roll to make poison in order to increase the potency, which adds your proficiency bonus to the damage it deals. This additional damage bypasses resistance to poison.
