From publisher blurb:
Like a little mad science in your fantasy? What if Dr. Frankenstein or Dr. Moreau could manipulate the Weave? Where do the hybrid creatures and characters come from in your game? Introducing: the Biomancer.
Biomancers have learned to use the Weave to manipulate life itself, accessing a form of magic unavailable to most wizards. While other wizards can use Biomancy spells, they lose their proficiency bonus due to the strangeness of the magic.
This supplement includes 4 subclasses, 11 new spells, and 3 new backgrounds.
Some consider biomancy unnatural, but it’s the biomancers of Tanmaa who are responsible for many of the hybrid and augmented creatures who fill the Western Division of Caphora, and while biomancers have been blamed for some of the plagues that have struck the continent, they’re the first to be called when plague strikes to control it.
Most biomancers are found in the labs of Tanmaa, but some nobles hire them as extremely expensive personal physicians. Some biomancers are the products of their own labs who have learned, through observation and sometimes deliberate training, to use the very magic that created them.
Biomancers specialize in one of four forms of the craft: Somaturgy, Neuroturgy, Amalgamism, and Miasmism. They can use other biomancy spells but prefer their own tradition.
