Cynth approached the first vendor that she saw that seemed as though they might be selling what she needed. "Please," she said, keeping her voice as steady as she could, "I need a compass and... four supply packs." She leaned heavily on the vendor's counter so that she could use her crutch-handling arm to search through her bags of things for her small collection of tokens. She surely had enough, right?
(For reference, Cynth's Charisma skill is at +2.)
