Grand Evolutionary Mutagen (Su)
Prerequisites: Alchemist 16, Greater Evolutionary Mutagen discovery.
Benefit: When the alchemist selects this discovery, he chooses one evolution from the eidolon’s list of 4-point evolutions. His mutagen grants this evolution instead of the normal mutagen effects, if he chooses to do so. This discovery can be selected more than once, but each time it is selected it provides a different 4-point evolution.
