Prerequisite(s): An alchemist must have the infusion discovery before selecting this discovery.
When the alchemist creates an infusion, he can mask a delayed poison within the mixture. A nostrum can contain only an ingested poison, and the save DC of the poison is reduced by 2. The poison takes effect a number of hours after being imbibed equal to the alchemist’s Intelligence bonus (minimum 0) decided by the alchemist at the creation of the nostrum. The poison within a nostrum can be detected as normal by spells such as detect poison and similar abilities. Until the nostrum is consumed or destroyed, it continues to occupy one of the alchemist’s daily extract slots.
