Shapechange:

This mystical skill requires an initial 10 point cost be paid before the character can gain any ranks and his first shapechange ability.  For each rank of shapechange a character can choose one closely related family or order of creature that he may alter his body to resemble.  Examples would include the horse family, raptors, bats, etc.  The character would not be able to assume exotic or monstrous shapes, like dragons or slime molds,  until he has at least eight ranks of shapechange.  The character can assume any shape, but he is restricted in altered size to no less than 1/8 his height (or length) and no more than 2x his height (or length  Thus he could change into an elephant, but it would be a small elephant.  When in his altered form the character will be able to use any of the natural abilities of the creature whose form he has assumed.  If he is a fish, he can breath water, if he is an eagle he can fly.  The shapechaged character can not use any of the magical or special abilities of the creature.  If he shapechanged into a basilisk he could not petrify another with his gaze.  A shapechanged character retains all of his normal attribute scores, faculties, skills, and the ability to speak.
