Glancing at his options, Sam spots a katana. Nice, lightweight, cool looking symbols down the length of the blade. It strikes him as the most badass option. However, as soon as he grabs the hilt, he finds his hand stuck to it, and burning, as the symbols on the blade glow blue, and send shimmering tendrils of light down the length of his arm, encircling his body. Muscles stretch, and bones creak as his body begins to reshape itself, becoming smaller over all, losing a full foot of height and a fair bit of fat. At least, from his stomach. His chest begins to itch as a pair of preposterously large breasts burst forth, and an uncomfortably sudden tension in his pants as if some hand inside his pelvis were reaching forward and tugging everything back farther suggested he was fully becoming a woman. As he gasped and groaned from the pain, his new sensually pitched voice certainly helped the theory along, and his hair grew out preposterously long, turning a vivid red.
Once the pain stopped, he, or she now, glanced around, taking a few experimental steps with his new center of balance, and saw the rest of the weapons had disappeared, like the dice, and there was no real choice but to wander out to the forest path that had replaced the modern street once laying outside the shop's door.
Having only the one simple path to follow, Sam started walking, trying to ignore the sensations of an empty crotch, and pendulous breasts bobbing along with every step. Annoyance and some curiosity only lasted so long however, as soon a massive werewolf burst out from the trees with a nasty snarl. Hopefully the cursed katana was at least effective here.
