Prerequisites: Eidolon clas feature
Benefit: When the alchemist selects this discovery, he chooses one evolution from the eidolon’s list of 1-point evolutions. His mutagen grants this evolution instead of the normal mutagen effects, if he chooses to do so. The evolutionary mutagen must be injected into his eidolon as a standard action, and this causes discomfort, resulting in the eidolon being sickened for 1d4 rounds. This discovery can be selected more than once, but each time it is selected it provides a different 1-point evolution.
