Yes, but which halfling can I have as a cohort, henchman, or PC who physically looks human by being 5 ft. and 5 in. tall and with a human weight range? In other words, I want my character to be medium or man-sized so that I can be a nonhuman half-a-man who looks human. For ADandD 2nd edition, does a 5 ft. and 5 in. tall halfling who has a human weight range count as a created new race or does it count as a subrace--does a different subrace count as a created new race?
