From publisher blurb:
Adapt. Evolve. Overcome.
Horradin are masters of an exotic art of temporary evolution; they are adaptable adventures that evolve to overcome any challenge! Less “mad alchemist” or arcane transmuter, horradins instead embody the power of magical creatures through the lens of forced adaptation. First developed from a study of molting insects, the magical art has advanced and taken on new aspects. By entering various ‘stages’ of a magically evolving form, a horradin is able to rapidly grow more powerful in combat or other dramatic situations.
Includes:
Full Base Class: The full horradin base class for Pathfinder 1st Edition! It is a d12, full BAB, martial class that focuses on adaptive evolution and reaching increasingly more powerful forms during combat!
5+ Evolutionary Branches: Try all of the various thematic forms of evolution! From the classic “insectoid” evolutions to the ki-blasting “power-up” style, the horradin covers a lot of ground!
10 Adaptations: Modify your evolutions to match your wants and needs! Grow extra arms, change skin color like a chameleon, gain new senses, or become venomous. These are incorporated into your various evolutions.
10+ Developments: If adaptations teach your horradin new ways to evolve, developments are new tactics and new ways to apply those evolutions!
