Torturous Transformation
At 7th level, a vivisectionist adds anthropomorphic animal to his formula book as a 2nd-level extract. When he uses this extract, he injects it into an animal as part of a 2-hour surgical procedure. By using multiple doses of this extract as part of the surgery, he multiplies the duration by the number of extracts used.
At 9th level, a vivisectionist adds awaken and baleful polymorph to his formula book as 3rd-level extracts. When he uses the awaken or baleful polymorph extract, he injects it into the target (not a plant) as part of a 24-hour surgical procedure. He can make anthropomorphic animal permanent on a creature by spending 7,500 gp.
At 15th level, a vivisectionist adds regenerate to his formula book as a 5th-level extract.
