Not mine, but a collaborativr effort: Young dryad loses physical body and is imprisoned in a robotic shell. She escapes and now all of her former magical druid powers are a combination of mechanical contraptions and just a dash of magic. She runs on magic energy, but her acid spray cantrip is truly a small vaporizer embedded in her palm. Really cool, but the Player stop playing that char vecause we restricted her wild shape to much :/ in hindsight, i really dont like my dming decisions regarding that char
