You are now able to change your from Human (or whatever Physical Race Changes you had) to a new race or even a hybrid between various races. This selection of races is initially limited to the options available in both D&D and Pathfinder. You are able to change your race beyond this initial switch as well, to do so you must both have enough XP and meet the qualifications for the new race. You will never be unsatisfied with the results of your new race or hybrid.
