Nah. He was just a fighting man. As a primary influence on the original game, Conan's prowess was a function of high stats and canny play. Remember, when Gygax and Arneson invented the game, there wasn't even a thief class. Conan was a thief because he broke into tombs, palaces and treasures and stole things. He was a barbarian because he came from the hinterlands and disdained "soft" civilized folk. Only later did people try and formalize those traits with class abilities -- and things have been going down hill ever since.
