Lingering Plague

This discovery is available to any alchemist who qualifies, though it is more common among ratfolk alchemists.

Prerequisites: Alchemist 8

Benefit: Any creature that must make a save against a disease caused by the alchemist's extract or other class ability must make a second save 1 round later to avoid doubling the duration of the disease effect. If the disease doesn't have a duration, this discovery reduces its onset time and frequencies by half.
