Devious Painting Ⅲ

What all Devious Paintings have in common is special markings highlighting a particular location. Further investigation indicates that these locations all contain special items. However, when collecting these items, test subjects had a █% chance of randomly losing one of their own items, such as money, gloves, headphones, or even a personal quality or ability. One young artist who participated in the experiment reported losing his ability to draw. Other subjects, however, appeared to lose nothing. It has not yet been determined how this "exchange" mechanism works.
