Master Poisoner

Your expertise in toxicology grants you the following benefits:

• Increase your Dexterity or Intelligence score by 1, to a maximum of 20.
• You gain proficiency with the poisoner’s kit. You have advantage on ability checks associated with the poisoner’s kit.
• As an action, you can automatically detect the presence of any nonmagical poison within 5 feet of you that you can see or smell.
• Enhance Poison: You can dedicate 1 hour to improving an existing poison. This requires you to have a poisoner’s kit and to spend 10% of the poison’s initial value in special ingredients. Improving a poison increases its DC by your proficiency bonus. You can improve the same poison only once. When you fail a saving throw against a poison, you can use your reaction to reroll it. The result of the second roll replaces the first.
