From publisher blurb:
They Could Be Anyone!
Legendary Hybrids: Skinchanger is the latest volume in our series of class-focused player supplements, introducing a new series of hybrid classes like those in the Pathfinder Roleplaying Game Advanced Class Guide that blend the core elements of two different base classes into a unique synergy all their own. The skinchanger brings you a 20-level hybrid class that combines the druid's shapeshifting with the vigilante's flexibility and brilliantly devious ploys. They can transform into almost any shape and pass as anyone they have studied. Those who survive learning of these secretive operatives struggle endlessly with the fear that anyone they meet, no matter how trusted, might be a disguised skinchanger watching for the perfect opportunity to strike. Customize your shapeshifting hero with over 50 brand-new vigilante talents and skinchange options from anonymous persona, flexible grace, and celebrity lookalike to potent powers like metamorphic dodge, colossal form, impossible agility, and reality is unrealistic! Plus get favored class options, unique class feats like Form Finesse and Memorized Personae, and take on an awesome archetype like the shape-blending chimerist, the moon-mad lycanthrope aspirant, or the deadly shape thief!
