Prerequisite(s): Aberrant bloodline.
Benefit: You gain a tumor familiar, as the tumor familiar alchemist discovery, with an effective alchemist level equal to the level of the class that grants your aberrant bloodline for determining the tumor familiar’s abilities. If multiple classes grant you the aberrant bloodline, those class levels stack for determining your effective alchemist level.
