One of my PC's in my Pathfinder 1st edition game is a Ratfolk and has this item:
Mask, Stalkers
Preserved sections harvested from several different human faces cover this mask. When worn, the mask desaturates the wearer’s color, making him appear shadowy and granting a +5 competence bonus on Stealth checks. Once per day as a full-round action, the wearer can cause the mask’s features to take on the appearance of any creature of the wearer’s basic size and shape within 60 feet that he observes, allowing the wearer to adopt that creature’s appearance for 1 hour. This grants him a +10 bonus on Disguise checks made to appear as the creature. The mask also grants the wearer a +1 bonus on attack rolls and weapon damage rolls made against the creature he is disguised as, as the mask builds upon the wearer’s rage and jealousy of the target’s appearance.
Being category small as a Ratfolk, he wouldn't be able to take on the guise of a medium sized person, would that be how one would interpret the same basic shape and size statement.
Thanks for your aid.
