Choose a type of poison, such as injury, contact, ingested, or inhaled. All such poisons that you craft are more deadly than normal. Prerequisite: Craft (poisonmaking) 5+ ranks
Whenever you create a poison of the chosen type, the Fortitude DC to resist the poison's effects increases by +2. This adjustment applies to both the initial and secondary saving throws.
You may select this feat more than once. Each time you select the feat, it applies to a different type of poison.
